HKS Brake Fluid Racing Pro Brake Fluid (500ml)

Brake fluid is hygroscopic: it absorbs water from the air. An opened container loses its properties within a few months, and water in the system causes the fluid to boil under stress, resulting in the pedal going to the floor. Use a new container and flush the entire system.

Do not mix fluid families: silicone-based DOT 5 is not compatible with glycol-based DOT 4 or DOT 5.1.
