Brake Bleeding: Service and Repair
Master Cylinder Bleeding
CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is spilled onto a painted or plastic surface immediately wash it off
with water.
When a new brake master cylinder has been installed or the brake system emptied or partially emptied, air may be trapped in the master cylinder. Use
the following procedure to remove air from brake master cylinder.
1. Locate the two bleed screws on the engine side of master cylinder.
CAUTION: Use only bleed screws on engine side of brake master cylinder. Hydro-booster bleed screw located near the dash on the
hydro-booster casting is for the booster cavity filled with power steering fluid, not brake fluid.
2. Attach drain tube to bleed screw brake master cylinder closet to booster. Submerge end of drain tube in container partially filled with clear brake
fluid. Loosen bleed screw approximately three-quarters of a turn.
3. Have assistant push brake pedal down slowly through full travel, close outlet fitting; then return brake pedal slowly to full released position. Wait
five seconds; then repeat operation until air bubbles cease to appear.
4. Repeat Steps 2 and 3 for bleeder screw farthest from hydro-booster.
