• Press the brake pedal several times to deplete the vacuum in the brake booster.
• Be careful when handling the master cylinder. Do not hold it at the piston, or the piston may separate from the body. If the piston separates from the body, then the master cylinder must be replaced. Do not reinsert the piston back into the master cylinder body.
