Brake fluid is the lifeblood of automotive brake systems. It must transmit high pressures through brake lines to actuate brakes on all four wheels without leakage through the seals.

Automotive brake fluid contamination can cause brake malfunction such as brake lockup, increased stopping distance or no braking at all. Brake fluid is alcohol-based and designed to resist heat and absorb whatever moisture enters the brake system.

The rubber seals in the brake system are designed to handle brake fluid but not other types of 1,000 pounds per square inch. Consequently, any damage to seals from contamination can be catastrophic.
