Quick Answer: What brake fluid do I use in a motorcycle?

For most motorbike use, it is only DOT 4 and DOT 5.1 that you need to concern yourself with, and it is likely that it will be one of these fluids that is recommended for your motorcycle. As DOT 5.1 is more hygroscopic than DOT 4 and therefore absorbs more moisture, it will need to be changed more often.

What kind of brake fluid does a motorcycle use?

A DOT4 brake fluid used in a motorcycle is exactly the same DOT4 brake fluid used in a car. There is no difference in the brake fluid at all. Within the brake fluids, there are different types – DOT 3, DOT 4, DOT 5, DOT 5.1 etc. These type of brake fluids have different boiling points and usability.

Can you use car brake fluid in a motorbike?

Is automotive and motorcycle brake fluid the same? Yes. You can use automotive brake fluid in a motorcycle.

Can I use DOT 5 brake fluid in my motorcycle?

DOT 5 brake fluid is stipulated for nearly all motorcycles from Harley-Davidson and Buell roughly from model years 1976 to 2004/2005 with original braking systems.

Can I use DOT 4 instead of DOT 3?

Yes, DOT 3 brake fluid is compatible with DOT 4 brake fluid. However, DOT 4 offers a higher boiling point. … It’s compatible with DOT 3 and DOT 4 fluid. DOT 5 brake fluid is silicone, meaning it doesn’t absorb water.

Can I use DOT 4 for bike brakes?

most brakes use Dot 4 which is the same as most cars. Shimano use mineral oil ( a bit like Citroen LHM oil in the link below) which is not compatible and you can’t use Dot 4 in shimano brakes or mineral oil in brakes that use dot 4. Some brakes may say dot 5.1 but this is compatible with dot 4.

What is the difference between DOT 4 and DOT 5.1 brake fluid?

DOT 5.1 fluids are a development of DOT 4 having not only higher boiling points (and retaining them even better than DOT 4 in service) but also having a much improved viscosity (thickness) at low temperatures.

Can I use any brake fluid for my bike?

There are two types of brake fluid used in mountain bike brakes today. DOT fluid and mineral oil. Which one you use is not up for discussion, you should only use the fluid your brake was designed to use. Introducing the wrong fluid into your brake will have adverse effects on your brakes performance.

Is all DOT 4 brake fluid the same?

Since DOT 4 and 5.1 are both glycol-based brake fluids they are compatible with each other, which means they can be readily mixed without harming your brake system. It is important never to mistake DOT 5.1 (glycol-based) with DOT 5 which is silicone-based and should never be mixed with any other DOT fluid.

Can you use DOT 4 instead of mineral oil?

No, mineral oil and DOT brake fluid are different and are NOT compatible.

Which brake fluid should I use?

By far, DOT 3 is the most popular. It’s been in use for a very long time. Fresh DOT 3 has a boiling point of 401 degrees Fahrenheit; fully degraded, it drops to 284 degrees Fahrenheit. This makes your brake fluid much more likely to boil.

What is DOT 5.1 brake fluid?

BRAKE FLUID DOT 5.1 is a brake fluid for hydraulic brake and clutch systems with a boiling point of at least 260 °C and an extremely high wet boiling point of at least 180 °C. Because of the low viscosity at low temperatures, particularly suitable for additional systems, such as ABS and ASR.

What is DOT brake fluid motorcycle?

For most motorbike use, it is only DOT 4 and DOT 5.1 that you need to concern yourself with, and it is likely that it will be one of these fluids that is recommended for your motorcycle. As DOT 5.1 is more hygroscopic than DOT 4 and therefore absorbs more moisture, it will need to be changed more often.

What happens if you use the wrong DOT brake fluid?

Using the wrong fluid can cause poor lubrication, overheating, and possibly transmission failure. A mechanic might not be able to reverse the damage, even by flushing the transmission. Mistakenly adding motor oil or brake fluid can also destroy your transmission.

What happens if I mix DOT 3 and DOT 4 brake fluid?

Originally Answered: Is it possible to mix DOT 3 and Dot 4 brake fluid in your car? Yes. DOT 3 and DOT 4 are both glycol ether based, and will mix just fine. DOT 4 has a higher boiling point, so depending on the application, it may be necessary to use that instead of DOT 3.

What is DOT 5 used for?

DOT5 is a silicone-based fluid that was developed for use where moisture or water was almost certain to be a factor in the braking system, such as military applications. While DOT5 has a higher boiling point (500F dry/356F wet) than DOT3 or DOT4, DOT5 exhibits more compressibility than glycol ether brake fluid.
