Symptoms of a Failing Power Brake Booster:

• Stiff brake pedal that is extremely hard to push
• Longer stopping distance
• Engine stalls when brakes are applied

Prior to replacing your Power Brake Booster:

• Ensure the Vaccum Hose is properly connected and not loose
• Check the Vaccum Hose for a blockage or leak
• Inspect the Check Valve for cracks, looseness or damage

Testing your Power Brake Booster:

• With the engine off, pump the brakes 5-6 times
• Turn the engine on while pushing down lightly on the brake pedal
• If your brake booster is working, the pedal will sink down about ¼”
• If your brake booster is not working, nothing will happen or the brake pedal will push back against your foot
