Removal Procedure
Warning
The accumulator contains compressed gas. Always use the proper tools and follow the recommended procedures or personal injury may result. Do not
apply heat to accumulator. Do not attempt to repair an inoperative accumulator. Always replace an inoperative accumulator with a new one. Dispose of
an inoperative accumulator by drilling a 1.5 mm (1/16 in) diameter hole through the end of the accumulator can, opposite the O-ring.
Warning
Push rod removal is not recommended. Improper staking of the push rod to the Hydroboost reaction piston can result in a loss of brakes. If the rod or
seals require service, the entire unit must be replaced.
1. Depress brake pedal at least ten times to relieve pressure in the accumulator.
2. Remove the master cylinder from the hydraulic booster. Do not remove the brake pipes. Set the master cylinder aside in the engine compartment.
