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.

What brake fluid does a Harley-Davidson take?

Harley-Davidson used DOT 5 until a decade ago but specifies DOT 4 now that all their bikes have ABS. Okay, back to the common glycol-based fluids then. The difference between DOT 3, 4, and 5.1 comes down to boiling point, and the higher the boiling point, the more abuse and heat the fluid can take.

Can I use DOT 4 instead of DOT 5?

Can You Mix DOT 5 and DOT 4? No, DOT 4 is glycol-based, making it fundamentally incompatible with DOT 5 brake fluid. If your fluids do get mixed, you’ll need to flush the entire system multiple times to remedy the situation.

What type of brake fluid do motorcycles use?

The DOT 4 brake fluid is the widely used fluid in motorcycles. Within DOT 4 there are different sub types like – DOT 4 Plus, DOT 4 Low Viscosity, DOT 4 Racing etc. While a DOT 3 or a DOT 4 absorbs water, a DOT 5 does not.

Should I use DOT 5 brake fluid?

As a rule, vehicles equipped with anti-lock brakes (ABS) should not use DOT 5 brake fluid . DOT 5 brake fluid is silicone based. DOT 3 (standard) and DOT 4 (heavy-duty) are glycol-based. ... DOT 5 brake fluid does not become contaminated with moisture over time as conventional DOT 3 and 4 brake fluids do.

Can I put DOT 3 in a DOT 4 system?

Are DOT 3 and DOT 4 brake fluid compatible? Yes , DOT 3 brake fluid is compatible with DOT 4 brake fluid. However, DOT 4 offers a higher boiling point. DOT 5.1 is used in high-performance and heavy-duty applications due to its high boiling point.

Can I use DOT 3 instead of DOT 4 motorcycle?

DOT 4 is adequate and does a good job. The reason for not using DOT 3 is that if the brakes get hot enough, the fluid will boil and cause your brakes to fade. DOT 4 will not have any more or less braking power than DOT 3. There’s most likely air still in the lines.

Which is better DOT 3 or DOT 4?

The primary differences between the two include the following: DOT 3 brake fluid will absorb less water than DOT 4 from the air over time, meaning you’ll need to have your fluid changed less frequently. DOT 4 brake fluid has higher dry and wet boiling points, making it safer for higher temperatures.

Can DOT 5 replace DOT 3?

DOT 5 can be used as an upgrade or replacement for both DOT 3 and 4 , but should not be mixed with any of the other fluids. The procedures to convert your DOT 3 or 4 systems to the silicone-based DOT 5 are similar to the Dot 4 conversion procedure mentioned above.

Can I use DOT 3 in a DOT 5 system?

All DOT 3, 4 and 5.1 brake fluids are compatible with each other and with all systems. All polyethylene glycol-based fluids will not harm healthy rubber parts.

Can DOT 4 and 5.1 be mixed?

Yes, brake fluids conforming to DOT 3, Dot 4 and DOT 5.1 can safely be mixed although the performance of the higher specifica on products will be diluted. Silicone (DOT 5) and mineral-based brake fluids should never be mixed with any other types.

What happens if you mix DOT 3 and DOT 5 brake fluid?

They are incompatible and if mixed, brake failure may occur. Moreover, there are serious compatibility issues when using DOT5 in a system that was engineered to use DOT3 or DOT4. Also, users should take care not to mix DOT3 and DOT4 fluids as there may be brake system compatibility issues.

Can you mix old and new brake fluid?

Brake fluid is prone to absorbing water, which is one of the reasons you replace it. You CANNOT reuse fluid, and you CANNOT mix old with new.

What are two advantages of DOT 5 brake fluid?

DOT 5 Strengths:

2) Doesn’t absorb moisture . 3) Doesn’t remove paint. 4) The viscosity is more stable over the extremes of temperature. 5) With the exception of some formulations used in external boots, silicone brake fluid is compatible with all standard brake components.

Is it OK to mix brake fluid brands?

It will not do any damage to your vehicle when mixing brands. The thing you should keep in mind is that you need to put the same DOTX in your car if you refill. DOT4 will perform a little better than DOT3 as it is more resistant agains higher temperatures.
