Can i use any dot 4 brake fluid for motorcycle

Every bikes and autos use brake fluids as part of their braking strategies.

Do these brake fluids match and are one and the similar is the question.

Is motorcycle brake fluid completely completely different from vehicle? There’s no distinction throughout the motorcycle brake fluid and the auto brake fluid. The motorcycle and the automotive fluid are one and the similar. If every the auto and the motorcycle have the similar DOT scores, then they primarily use the similar brake fluid in them.

Enable us to deep dive into the specifics of the brake fluid utilized in these autos.

Is Motorcycle And Vehicle Brake Fluid The An identical

There’s no distinction throughout the motorcycle brake fluid and the auto brake fluid. The motorcycle and the automotive fluid are one and the similar.

Every the auto and the motorcycle use the similar brake fluids.

A DOT4 brake fluid utilized in a motorbike is strictly the similar DOT4 brake fluid utilized in a vehicle. There’s no distinction throughout the brake fluid the least bit.

All through the brake fluids, there are different types – DOT 3, DOT 4, DOT 5, DOT 5.1 and lots of others.

These sort of brake fluids have completely completely different boiling elements and usefulness.

Nonetheless, a DOT 4 actually helpful in a motorbike and a DOT 4 actually helpful in a vehicle will use the similar DOT 4 brake fluid.

There’s utterly no distinction between these brake fluids used throughout the vehicle and the motorcycle.

If every the auto and the motorcycle have the similar DOT scores, then they primarily use the similar brake fluid in them.

Utterly completely different Brake Fluid Varieties

The brake fluid is classed and rated by a amount preceded by DOT.

The ‘DOT’ proper right here refers to Division Of Transportation. And the amount represents completely completely different sort and boiling elements.

Bigger the DOT amount, elevated could be the boiling stage of the brake fluid.

In numerous phrases, a DOT 5 has the subsequent boiling stage than a DOT Three or a DOT 4.

The DOT 4 brake fluid is the broadly used fluid in bikes. Inside DOT 4 there are completely completely different sub varieties like – DOT 4 Plus, DOT 4 Low Viscosity, DOT 4 Racing and lots of others.

Whereas a DOT Three or a DOT 4 absorbs water, a DOT 5 does not. DOT Three and DOT 4 eat paint as correctly.

On the flip aspect, the upper traits of DOT 5 comes at a worth because it’s extraordinarily pricey – 4x events than DOT 3.

Listed beneath are just some thumb pointers to adjust to regarding brake fluids.

  • Do not mix brake fluid varieties. A DOT 5 is strictly not allowed to mix with each different fluids. Whereas DOT Three and DOT 4 are technically mixable, it is nonetheless NOT actually helpful since they will react badly and corrode the brake system.
  • Do NOT use DOT Three in your motorcycle since its boiling stage is simply too low. The brake system will not work accurately with DOT 3.
  • Choose the becoming brake fluid based mostly totally on the producer’s suggestion from bike proprietor’s information.
  • Change the brake fluid every 2 years. Absolutely drain the current fluid and alter with a model new one.

Can I Mix Outdated And New Brake Fluid

It is NOT actually helpful to mix the earlier and new brake fluid.

It is as a result of, the moisture and the water content material materials absorbed by the earlier brake fluid will nonetheless exist throughout the braking system in case you occur to mix the earlier and new brake fluids.

The contaminated particles which have infiltrated the fluid goes nowhere besides drained out. And the effectivity of the earlier brake fluid which has deteriorated acquired’t change and might proceed with the poor effectivity.

As long as the earlier and current brake fluid nonetheless stays throughout the system, the braking effectivity acquired’t be improved drastically. In addition to, after some time, the current earlier brake fluid will really deteriorate even extra in prime quality.

That’s why, the earlier and new brake fluid should not be mixed. The topping up is okay if the brake fluid won’t be too earlier. Nonetheless, it is on a regular basis advisable to not mix and drain the earlier fluid completely sooner than filling up with the model new one.

How Normally Must You Change The Brake Fluid In Bikes

The most effective change interval for brake fluid in a motorbike is 2 years.

That’s primarily on account of the brake fluid absorbs water and extra time the water content material materials throughout the brake fluid will start corroding the metallic elements associated to the braking system.

For an in depth description, check out our put up on frequency of brake fluid change.

Is All DOT4 Brake Fluid The An identical

The Dot 4 brake fluid in a motorbike and the DOT 4 brake fluid utilized in a vehicle or each different automobile – are all of the similar.

A DOT 4 brake fluid utilized in any automobile may be of the similar traits and boiling stage. There’s no distinction the least bit between the DOT 4 fluid used all through completely completely different automotive.

Inside DOT 4, there are completely completely different brake fluids like DOT 4 Plus, DOT 4 Low Viscosity, DOT 4 Racing and lots of others. These fluids are barely completely completely different though with differing boiling and hygroscopic traits.

How Do I Know What Type Of Brake Fluid I Have

In case your motorcycle brake fluid has not been modified since you can have bought it from the manufacture, it’s possible you’ll merely get to know the brake fluid sort by checking the proprietor information.

Throughout the bike’s proprietor information, go to the Specs half and scroll by means of to look at the brake fluid.

When you have got modified the brake fluid each by your self or your provider or service retailer, then you need to recall the brake fluid used or look at alongside along with your provider on which kind they’ve utilized in your motorcycle.

How Do You Know If Your Motorcycle Brake Fluid Is Harmful

For those who’re not able to apply brakes simply and are going by way of braking factors in your motorcycle, then the motorcycle brake fluid has degraded in prime quality and effectivity.

When the brake fluid is unhealthy and deteriorated in its prime quality, you need to change the fluid with a model new brake fluid.

A foul brake fluid can have absorbed water and contamination which has deteriorated its effectivity and efficiency.

So, change the fluid as rapidly as you uncover the brake fluid is unhealthy.


The motorcycle brake fluid is similar as vehicle. Every these vehicles use similar types of brake fluids.

Inside brake fluids there are different types – DOT 3, DOT 4, DOT 5 and lots of others.

Use the actually helpful brake fluid in your motorcycle and under no circumstances mix one brake fluid sort with one different.

Can i use any dot 4 brake fluid for motorcycle

When you end up utilizing at velocity it’s essential make sure that your brakes aren’t going to assist you to down and {{that a}} braking failure isn’t the penultimate experience of your life.

A essential part of a motorbike’s braking system is the brake fluid, nevertheless many bikers are unsure of the best way it really works and the importance of using the best brake fluid for his or her bike. A lack of understanding of brake fluids could have catastrophic outcomes for a rider, so proper right here we set out the information that every biker should know.

Background to Brake Fluid

Brake fluid, which is a hydraulic fluid, is answerable for transferring the elements of your bike’s braking system. With out this fluid, which operates beneath every extreme temperature and extreme pressure, your bike would not be succesful to stop when you brake. The pressure of the brake fluid causes the brake pads to squeeze down on the disc, which slows and finally stops the wheel rotating.

The early brake fluids contained castor oil-based hydraulic fluids and alcohols similar to butanol and ethanol. These fluids had been used sooner than brake fluid guidelines had been established, and it is the DOT 2 customary that offers for these oil-based brake fluid.

The DOT by which a number of sorts of brake fluid are acknowledged comes from The US Division of Transportation (DoT) that classifies brake fluid.

After castor oil-based brake fluids bought right here Glycol-based fluids which fall beneath the DOT 3, 4, and 5.1 necessities. Following these Glycol-based fluids bought right here Silicone-based fluids which usually fall beneath the DOT 5 necessities, although they aren’t as broadly used as a result of the Glycol primarily based brake fluids.

There are three vital measures used to set a fluid’s final DOT rating that clients ought to focus on:

  • Moisture resistance
  • Heat resistance
  • Viscosity

Your brake fluid’s talent (or lack of talent) to face up to heat harm and moisture has a serious impression on its effectivity, and consequently on the effectivity of your bike’s braking system.

Implications of DOT Rankings

The DOT number of a brake fluid gives you with an considered how the fluid will perform on the extreme temperatures generated by fastened arduous braking or in most likely essentially the most extreme climatic temperatures.

For a lot of bike use, it is solely DOT 4 and DOT 5.1 that you need to concern your self with, and it is most likely that may most likely be thought of one among these fluids that is actually helpful in your motorcycle.

As DOT 5.1 is additional hygroscopic than DOT 4 and as a result of this truth absorbs additional moisture, it must be modified additional sometimes. Nonetheless, the benefit of 5.1 with its elevated boiling stage, is that it could nicely experience elevated temperatures than DOT 4 sooner than it begins to affect braking effectivity. Although, an excellent prime quality DOT 4 fluid such as a result of the Super DOT4 which has a dry boiling stage which exceeds the 5.1 minimal shall be succesful to deal with the temperature ranges it would experience on a monitor day, for example. The Super DOT4, similar to the DOT 5.1 must be modified additional sometimes than DOT4 with the obvious worth vary implications.

DOT 5.1 maintains a lower viscosity in lower temperatures than DOT 4 all one of the best ways proper right down to spherical -40 ranges C, although that’s unlikely to be associated throughout the UK. Due to this, DOT4 is normally an relevant choice of brake fluid and requires altering a lot much less sometimes.

Frequency of Fluid Change

Hygroscopic brake fluids must be modified every 1-2yrs as a result of rising water content material materials due to moisture absorption. As a rule of thumb, the higher the DOT amount, the higher the absorption payment and as a result of this truth the additional sometimes the fluid have to be modified.

DOT 5 brake fluid won’t be hygroscopic and as a result of this truth does not need to get changed due to the rising water content material materials. As a rule, silicone fluid must be used solely to fill strategies that have not been beforehand filled with glycol-based fluid. A system that has used glycol-based fluid (DOT 3/4/5.1) will inevitably comprise moisture and glycol fluid disperses this moisture all by way of the system and includes corrosion inhibitors. Silicone fluid nevertheless does not allow moisture to enter the system, however moreover does not disperse any that is already throughout the system each. A system that has been crammed from dry with DOT 5 silicone fluid does not require the fluid to be modified at frequent intervals, nevertheless solely when the system has been disturbed by a ingredient restore or renewal. Silicone fluid utilization is highest in chilly climates due to its viscosity effectivity.

Brake fluids which have completely completely different DOT scores can’t on a regular basis be mixed. DOT 5, for example, should under no circumstances be mixed with the glycol ether constituent of DOT 3, 4 and 5.1 because the combination with a silicone fluid may set off corrosion due to trapped moisture. DOT 2 should under no circumstances be mixed with any of the other brake fluids. As DOT 3, DOT 4, and DOT 5.1 are all based mostly totally on glycol esters they’re usually mixed. Nonetheless, the bike producer will state which brake fluid to utilize throughout the information and whereas it is attainable to maneuver as a lot as the subsequent performing brake fluid i.e. from DOT 4 to 5.1, it’s essential under no circumstances switch down from the producer’s suggestion. Various fluid producers advocate in opposition to mixing producers and DOT classifications on account of some chemical substances will not be appropriate. It is advisable that sooner than you add any brake fluid, that you just simply look at any stickers or warnings in your bike for added knowledge

One different tip when altering your brake fluid is that it’s essential on a regular basis use new fluid from an unopened bottle in order that you can ensure that it won’t be contaminated with water. Moreover don’t forget that glycol ether-based brake fluid will harm the paintwork of your bike if it comes into contact. DOT-5, because it’s silicone primarily based, won’t harm paint, although whether or not it’s spilt onto the paintwork, touching-up or restore of the paint may very well be subtle. DOT 5 was utilized by Harley-Davidson until all their bikes had ABS brakes fitted at which stage, they specified DOT 4, the standard brake fluid instantly.

Research Further About Venhill

The vital factor issue to remember about brake fluid is that it deteriorates over time, sometimes on account of moisture absorption. Due to this, it is vital that you just simply change your brake fluid sooner than it deteriorates to some extent when it compromises the effectivity of the brake system and threatens your life.

To get most likely essentially the most out of your brakes and motorcycle mainly, browse our fluctuate of braided brake traces proper right here at Venhill along with all our completely different merchandise.

Can i use any dot 4 brake fluid for motorcycle

There’s no denying that brake fluid is a very essential part of a motorbike’s brake system make-up.

The fluid is what transfers the stress we apply on the lever into pressure, so making certain that we’ve now the best fluid and that it is correctly maintained is one factor that every rider should take heed to.

Brake fluid has its private effectivity life and there are moreover different types on the market to us.

This info will ingredient why and the best way sometimes we should all the time change it, along with look into among the many completely completely different brake fluid varieties on the market for us to utilize.

Why brake fluid have to be modified

Glycol-based brake fluid (the most common for autos and bikes) is hygroscopic. Due to this the fluid will aggressively take up moisture.

As rapidly as a result of the seal is broken on the bottle the brake fluid will begin to absorb moisture from the air. At the same time as quickly because it’s sealed in your system (though it’s under no circumstances actually sealed) it might proceed to absorb moisture from points like rubber seals and hoses.

Over time as more and more extra moisture is absorbed you may get a build-up of water throughout the system, and it is that water that changes the effectivity traits of the brake fluid.

Fluid in its pure state won’t be appreciably compressible, nevertheless when that fluid is vaporised by extreme temperatures the following vapour may very well be compressed. This means the fluid is then a lot much less able to convert stress into pressure.

It’s due to this that brake fluids have very extreme boiling elements to battle this, nevertheless when moisture is absorbed into the fluid the boiling stage drops dramatically.

DOT 4 brake fluid for example has a boiling stage of spherical 230 ranges centigrade, nevertheless as quickly because the fluid absorbs ample moisture to the aim the place it is then made up of just a few % water, the boiling stage can drop as loads as 80 ranges C.

Due to this it have to be modified.

How sometimes to change it

For road use, it is endorsed that your brake fluid be change every 1-2 years. This may larger than most likely be completed as part of your service schedule.

On the monitor however you do not want to have any probability of experiencing any sort of effectivity drops given the extent at which you rely upon the brakes, so altering it earlier wouldn’t be a horrible thought. Spherical yearly if no extra in case you occur to do quite a few monitor days.

People will comment it must be modified way more often because it experiences way more heat, nevertheless when purchasing for the proper fluids from the proper producers you shouldn’t experience any effectivity drops due to overheating.

The differing kinds (DOT fluids)

The brake fluids of instantly ought to meet set requirements in an effort to be match available on the market. These requirements come from organisations similar to SAE Worldwide, or the native authorities equal.

The USA for example sometimes adjust to the SAE necessities, nevertheless make amendments to compensate for the big variations in environments between states e.g. Florida vs Alaska. It is the US Division of Transportation that classifies the fluid, which is the place the time interval DOT comes from.

Being throughout the UK, the fluid supplied proper right here may be supplied as DOT fluid.

There are only a few different types similar to DOT 2 (castor oil-based), DOT 3, 4, 5.1 (Glycol-based) and DOT 5 brake fluid (silicone-based – not a very helpful racing brake fluid).

For motorcycle use though – considerably on the monitor – there are solely two varieties you need to concern your self with, and it will larger than most likely be one among many following fluids that is actually helpful in your motorcycle.

DOT 4 vs DOT 5.1

DOT 5.1 is additional hygroscopic than DOT 4 so it absorbs additional moisture. Attributable to this it have to be modified additional sometimes.

A benefit of 5.1 is that it has the subsequent boiling stage, meaning it could nicely experience elevated temperatures than DOT 4 sooner than it begins to experience any adversarial outcomes. Having said that, an excellent prime quality DOT 4 fluid should be succesful to deal with the temperature ranges it would experience on a monitor day.

DOT 5.1 will even protect a lower viscosity in lower temperatures, correct proper right down to spherical -40 ranges C. Though as soon as extra, this shouldn’t have any standing on UK monitor days.

Which is greatest?

5.1 will perform larger on the extremes of use, nevertheless on the diploma at which your motorcycle goes to hold out on a monitor day then I contemplate {{that a}} good prime quality DOT 4 brake fluid goes to hold out to solely the similar diploma.

It’s similar to the semi vs completely synthetic oil debate, a very goes to give you slight benefits in effectivity, nevertheless a semi synthetic is larger than okay for the job.

Neither is ‘larger’ and every make very good effectivity brake fluids, nevertheless one risk merely makes additional sense for monitor riders.

Can you mix them?

Moderately than flushing the system empty and refilling (meaning you’d should bleed the brakes), there’s no motive why it’s possible you’ll’t use your new sort of brake fluid to fill the reservoir as you pump out the earlier stuff – when going from DOT 4 to DOT 5.1 or vice versa, that is.

It’s best to however be sure you dispose of all the earlier fluid. Inserting 250ml+ into the system must be ample to see all the earlier stuff out.

Everytime you come to slam on the anchors after hammering your bike down the once more straight it’s essential be rattling sure your brakes are going to stop you. Having your brake fluid correctly maintained and in good state of affairs is a crucial issue to have in look at to allow that to happen.

There are clearly completely different hyperlinks throughout the braking system chain, nevertheless defending on excessive of your motorcycle brake fluid maintenance is one essential hyperlink to have doing its half.

    Polyglycol Primarily based DOT3 – Shade – Amber | One of many essential frequent finds accessible available on the market and have a specific for autos designed for the late 80s interval. Although appropriate with our CL7/9s should you can’t uncover the required chosen grade, this is not the best specification to be used from manufacturing unit suggestion pointers. DOT3 moreover absorbs moisture the quickest and has the underside boiling stage and can solely strictly be for road use.

    Polyglycol Primarily based DOT4 – Shade – Amber | The benchmark specs by almost all of vehicle producers, that’s moreover the actual grade to be used with Hondas/Acura autos irrespective of fashions. DOT4 is designed to absorb moisture slower than DOT3 and has the subsequent boiling stage. That’s every applicable for road use and monitor work. Whereas the OEM Honda DOT4 brake fluid is sufficient for weekend trackdays, meets and lots of others. Using racing specific DOT4 refined brake fluids will improve elevated temperature tolerance considerably beneath arduous braking circumstances.

    Silicone Primarily based DOT5 – Shade – Purple | Least frequent and likewise most likely essentially the most completely completely different from every grades above. DOT5 are primarily designed for autos not equipped with ABS fashions (Till in every other case producer specific)and this should not be used besides you’re utterly sure of what you’re doing. DOT5 does not take up moisture and holds the easiest boiling stage. This brake fluid won’t be appropriate with each courses above and can under no circumstances be mixed due to it’s chemical properties.

    Can i use any dot 4 brake fluid for motorcycle

    The primary distinction between DOT Three and DOT 4 brake fluid is their respective boiling elements.

    I believe I do know your subsequent question.

    Nevertheless first, some background. The U.S. Division of Transportation (DOT) classifies brake fluid into Four most vital courses:

    • DOT 3
    • DOT 4
    • DOT 5
    • DOT 5.1

    Their major variations are their moist & dry boiling elements and their composition.

    Dry Boiling Degree Moist Boiling Degree Composition
    DOT 3 205°C/401°F 140°C/284°F Glycol Ether
    DOT 4 230°C/446°F 155°C/311°F Glycol Ether/Borate Ester
    DOT 5 260°C/500°F 180°C/356°F Silicone
    DOT 5.1 260°C/500°F 180°C/356°F Glycol Ether/Borate Ester

    DOT Three is the most common sort utilized in autos and vans instantly. DOT 4, however, is gaining recognition due to widespread use of anti-lock braking strategies and traction administration, which revenue from DOT 4 fluid’s lower viscosity.

    Are DOT Three and DOT 4 Brake Fluid Applicable?

    Certain. DOT Three brake fluid is appropriate with DOT 4 brake fluid. Nonetheless, DOT 4 provides the subsequent boiling stage.

    DOT 5.1 is utilized in high-performance and heavy-duty features due to its extreme boiling stage. It’s appropriate with DOT Three and DOT 4 fluid.

    DOT 5 brake fluid is silicone, meaning it doesn’t take up water. It’s not appropriate with the other brake fluids and is used largely in fundamental autos that keep in storage for prolonged intervals and need a brake fluid that doesn’t take up water.

    Carry it to a Boiling Degree

    So, now we’re once more to boiling stage. What does it suggest? In the end, we’re not cooking these things.

    Properly, within the becoming working and ambient circumstances, you are cooking it.

    Aggressive braking may end up in intense heat, which could vaporize the brake fluid, leading to a spongy pedal.

    Aggressive braking may end up in intense heat, which could vaporize the brake fluid, leading to a spongy pedal.

    Braking generates intense heat between the brake pads and rotors. Maybe you’ve seen a race on TV the place the producers stick a GoPro beneath the auto to point the brakes truly glowing pink when the driving drive depresses the pedal.

    Intense heat can vaporize brake fluid, inflicting it to vary into compressible, which leads to a spongy feeling when you apply the brakes.

    That leaves gasoline throughout the traces, which is compressible, leading to a fragile pedal. In racing and performance-driving circles, that is named brake fade, and it’s one factor drivers actively have to stay away from. To drive as efficiently and safely as attainable, the driving drive need to be assured the brakes will perform on lap 10 as they did on lap one.

    Brake fade could come from the brake pad/rotor interface. The pads launch gasses, which reduces contact between the pads and rotors. That’s why high-end rotors are slotted and drilled – to launch gasses sooner, limiting fade.

    Brake Fade Isn’t Just for Racers

    Descending a steep hill, significantly when hauling a heavy load or towing a trailer, can generate tremendous heat in case you occur to expertise or pump the brakes.

    By the purpose you attain the underside, your pedal may go virtually to the bottom, making your coronary coronary heart payment go virtually by means of the roof.

    PRO TIP: Subsequent time, downshift proper right into a lower gear sooner than descending a steep incline.

    Must you want to toss your automobile spherical a curvy nation road for considerably treatment, standing on the brakes going into corners can create sufficient heat to set off brake fade, too. Must you get considerably too zealous, it is attainable you may end up going correct by means of a nook and into the woods.

    The fluid’s boiling stage signifies the temperature at which the brake fluid vaporizes. The higher the DOT classification, the higher the boiling stage, thus the upper the fluid is at resisting heat. That’s why racers use DOT 4, not DOT 3, brake fluid.

    Boiling Degree is Separated Into Dry & Moist Boiling Components

    The dry boiling stage is set using latest fluid straight from a model new container. The fluid’s moist boiling stage is set using fluid that’s been contaminated with 3.7% water, thus it’s on a regular basis lower than the dry boiling stage. Why would check out administrators contaminate good fluid? Because of it’s a reflection of what happens within the true world.

    Brake fluid is hygroscopic, meaning it absorbs water (in addition to silicone-based DOT 5 brake fluid). DOT Three fluid, for example, can take up as a lot as 2% water yearly. Moisture can enter the system when you take away the reservoir cap in order so as to add fluid, by means of worn seals and even by means of the rubber brake traces themselves. Thus the fluid’s moist boiling stage is the amount that additional exactly represents what’s truly taking place in your automobile.

    Since brake fluid can placed on out, it’s vital you alter it periodically. In every other case, not solely will your brakes turn into spongy and unsafe, the moisture will slowly corrode metallic elements.

    rule of thumb is to change the brake fluid every completely different 12 months in passenger autos, and never lower than yearly in racing autos. The AAA says 88% of motorists overlook brake maintenance, so that you just’re not alone in case you occur to haven’t modified brake fluid in awhile, like since you bought your automobile.

    It’s not too late to start, though. And when you do, check out our line of brake fluids in your automobile.
