Accumulator, Hydro-Boost Only





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
