REMOVAL AND INSTALLATION
Brake Booster —
Hydro-Boost
Removal WARNING: The power brake booster should not be carried by the accumulator, nor
should it ever be dropped on the accumulator. Check the snap ring on the accumulator for
correct seating before the power brake booster is used. The accumulator contains high-
pressure nitrogen gas and can be dangerous if mishandled.
WARNING: If the accumulator is to be disposed of, it must not be exposed to excessive
heat. 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.
1. With the engine off, depress the brake pedal (2455) several times to discharge the accumulator.
2. Disconnect the battery ground cable (14301). For additional information, refer to Section 414 -
01 .
3. Disconnect the fluid level sensor connector.
4. Disconnect the brake tubes.
