Power Brake Assist: Testing and Inspection

Accumulator - Hydro-Boost(R)
1. Start the engine and allow it to run for at least 5 minutes.
2. Stop the engine.
3. Apply the brakes. The accumulator in the Hydro-Boost(R) brake booster should retain enough pressure for at least 2 power assisted brake operations.
^ If no power assist is felt, install a new Hydro-Boost(R) brake booster.
^ If power assist is felt, the accumulator is operating correctly at this time.
