Bleeding Procedure: Notes
WARNING:
Hydraulic brake booster fluid is under high pressure, and may cause personal injury. When repairing hydraulic brake booster or ABS/TRAC/VSC system, bleed air out of hydraulic brake booster system.
CAUTION:
Brake fluid will damage painted surfaces. If brake fluid contacts a painted surface, wipe off immediately and clean with alcohol. Use only DOT 3 brake fluid from a sealed container. DO NOT mix brake fluid with any other type.
- Prior to bleeding brake system, bleed hydraulic brake booster. See HYDRAULIC BRAKE BOOSTER . Ensure reservoir is full. Raise and support vehicle. Remove wheels. Connect a vinyl hose to caliper bleeder plug and insert other end of tube in a clear container 1/4 full of brake fluid. Have assistant depress brake pedal several times then hold firm pressure on pedal. Loosen bleeder plug and bleed caliper. When fluid flow stops, tighten bleeder plug and have assistant release brake pedal. Repeat this procedure until no air bubbles are present in fluid. Repeat procedure for remaining calipers. Tighten bleeder plug to 97 INCH lbs. (11 N.m).
- With ignition switch in OFF position, depress brake pedal more than 40 times. As pressure in supply system is released, pedal reaction force becomes heavy and pedal stoke becomes shorter. Remove reservoir cap and add brake fluid as necessary.
