Brake Bleeding: Service and Repair
Hydraulic Brake System Bleeding (Manual)
1. Remove the booster reserve by applying the brakes several times with the engine OFF until all the reserve is depleted.
Important: If the master cylinder is known or suspected to have air in the bore, then it must be bled before any wheel cylinder or caliper
is bled.
2. Fill the master cylinder reservoir with brake fluid. Keep the master cylinder at least 1/2 full of fluid during the bleeding operation.
