Accumulator, Hydro-Boost Only
1. Start and run the engine.
2. Stop the engine.
3. Apply the brakes. The accumulator in the Hydro-Boost power brake booster should retain enough pressure for at least two power assisted brake operations.
If no power assist is felt, replace the Hydro-Boost power brake booster and retest the system. Refer to: Power Brake Assist / Hydraulic Brake Booster, Service and Repair
If power assist is felt, the accumulator is operating correctly at this time.
