Racing Brake Fluids
Can you use any kind of brake fluid in a race car?
The brake fluid you choose must be compatible with your race car's brake system and be able to handle the high temperatures on the track. Choose a high-performance brake fluid for your race car with a rating of DOT 4 or higher for maximum heat resistance.
How often should you change the brake fluid in your race car?
How often you change the brake fluid in your race car depends on how you run it. If you run short tracks with a lot of hard braking, change it after every race. For long tracks, a change after every couple of races is sufficient.
What are the minimum dry and wet boiling points of racing brake fluid?
The minimum dry and wet boiling points vary by the DOT of the racing brake fluid. DOT 4 brake fluid carries a minimum dry boiling point of 446°F (230°C) and a wet boiling point of 311°F (155°C). The minimum dry boiling point of both DOT 5 and DOT 5.1 brake fluid is 500°F (260°C) with a wet boiling point of 356°F (180°C). Some manufacturers engineer their brake fluids with higher boiling points; check the brand label for specifics.
