- Start and run the engine.
- Stop the engine.
- 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, install a new Hydro-Boost® power brake booster and retest the system.
