Preliminary Procedures Apply the park brake. Deplete the power reserve in the brake booster by applying the brake pedal several times until the pedal becomes firm. Without disconnecting the brake pipes, remove and position the brake master cylinder aside and support with heavy mechanics wire or equivalent.
