Bleeding Procedures

CAUTION: Use only clean DOT 3 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. Avoid spilling brake fluid on car, as it will damage paint. If brake fluid contacts paint, immediately flush with water.

NOTE: Check fluid level in master cylinder frequently during bleeding procedure.

Reservoir on master cylinder must be full at start of bleeding procedure. Refill reservoir after bleeding each wheel. Bleed brake system in proper sequence. See BRAKELINE BLEEDING SEQUENCE . Have an assistant slowly pump brake pedal several times then apply steady pressure. Loosen brake bleed screw to allow air to escape from system.
Tighten bleed screw securely. Repeat procedure until air bubbles no longer appear in fluid. Road test vehicle and check brake performance.
