Bleeding Procedures: Notes

CAUTION: Use only clean brake fluid. Ensure no dirt or other foreign matter contaminates brake fluid. DO NOT mix different brands of brake fluid, as they may not be compatible. DO NOT spill brake fluid on car, as it will damage paint. If brake fluid contacts paint, immediately flush with water.
CAUTION: Brake fluid is hygroscopic and consequently, takes on moisture from the air through vent hole in brake fluid tank. This could drop brake fluid boiling point from 464° F (240° C) to 320-356° F (160-180° C). Always check gasket in cap.
NOTE: Brake fluid must be replaced every 2 years.
