What is the best brake fluid for track?

Brake fluid is one of the most important components of the braking system. The purpose of brake fluid is to exert pressure on the piston of the calipers to bring the subsequently mounted pads into contact with the rotors converting hydraulic energy to friction, heat and noise which slows down your car. Here we review 58 different brake fluids.

This is not a ranking chart since Dry Boiling and Wet Boiling might be of different importance to people. For daily drivers look at wet boiling points and for race car drivers who will bleed after every race look at Dry Boiling. Each fluid a maximum operating temperature; if this number is exceeded, your fluid will boil and braking pressure will cease to exist.

Brake Fluid Review

Below is a list of the top automobile DOT 4 fluids separated by manufacturer, model, wet boiling point, dry boiling point, mixing compatibility and price. BuildJournal does not recommend DOT 5 nor DOT 3 brake fluids. Check out Stoptech’s explanation on the different types of DOT.

How Fluid Deteriorates Over Time

If moisture and/or water is introduced into the fluid, you can expect the maximum temperature the fluid can withstand to drop since water boils at a lower temperature than the fluid itself. So it is important to maintain your fluid at optimal life. No brake line is perfect nor packaging so the life of fluid is always dwindling with moisture seeping in from various places. Once your fluid boils, it no longer has the properties that exerts enough pressure on the pistons. You will only want to use a DOT 4 rated fluid which has the correct characteristics for a performance car.

*DOT stands for department of transportation and often provides specifications and safety regulations for car part manufacturers to adhere by.

Wet Boiling Point – Temperature that fluid boils with moisture.

  • The wet boiling point is more important than the dry boiling point as the latter is often tested in a lab under fresh fluid and ideal conditions.  You want to look at how it performs with moisture, since without a doubt moisture is going to be introduced into your fluid over time. You can think of this measure as an average performance rating of your fluid.

Dry Boiling Point – Temperature that fluid boils without moisture.

  • Occasionally, some fluids are known to hold their dry boiling point longer than usual. This is usually due to lower hygroscopicity rating of their fluid.

Mixing – Compatibility with other products.

  • Some fluids you can mix with others. Usually the boiling point will revert to the fluid with the worst characteristics. Sometimes fluid does not mix well with others and you should avoid mixing to prevent a failure.

Brake Fluid Recycling

We take if very seriously to recycle and properly dispose your old (and new) brake fluid. We encourage everyone to take the time to do so. There is a great article on YourMechanic.com on how to properly dispose brake fluid.
