Brake Fluid Accumulator: Testing and Inspection
Accumulator
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 2 power-assisted brake
operations. If no power assist is felt, install a new Hydro-Boost power brake booster and retest the system.
