Caution: Hydraulic brake systems use two distinct and incompatible fluids. Power steering fluid is used in the hydraulic brake booster system. Brake fluid is used in the master cylinder and brake pipes. Use extreme care when selecting brake system fluids, or seal damage can result. Refer to General Information to select the correct fluid.

Preliminary Procedures

1. Apply the park brake.
2. Deplete the power reserve in the brake booster by applying the brake pedal several times until the pedal becomes firm.
3. Without disconnecting the brake pipes, remove and position the brake master cylinder aside and support with heavy mechanics wire or equivalent. Refer to Master Cylinder Replacement.
