WARNING: The power brake booster must not be carried by the accumulator, nor should it ever be dropped on the accumulator. The snap
ring on the accumulator must be checked for proper seating before the power brake booster is used. The accumulator contains high-pressure
nitrogen gas and can be dangerous if mishandled. Failure to follow these instructions may result in personal injury.
WARNING: If the accumulator is to be disposed of, it must not be exposed to excessive heat, fire or incineration. Before discarding the
accumulator, drill a 1.6 mm (1/16 inch) diameter hole in the end of the accumulator can to relieve the gas pressure. Always wear safety
glasses when performing this operation. Failure to follow these instructions may result in personal injury.
1. CAUTION: Do not activate the brake booster with the brake master cylinder removed.
With the engine off, apply the brake pedal several times to deplete the brake booster accumulator reserve.
2. Disconnect the power steering pressure hoses.
3. Using the special tool, install new Teflon seals on the power steering pressure fittings.
