CARDONE Remanufactured Power Brake Boosters offer reliable stopping performance. Each unit is reverse engineered, where original design weaknesses are identified, corrected and where applicable upgraded to provide a more durable part than the original unit. Every unit is remanufactured to meet or exceed OEM performance, providing a quality product both you and your vehicle can rely on.

  • 100% O.E. parts are installed on every unit for like-new performance and reliability
  • All units are 100% vacuum tested to ensure reliable performance
  • Exclusive rust-prohibitive finishing process extends unit life
  • Master cylinder output rods are pre-adjusted (when included) for easier and faster installation
  • New mounting nuts and washers ensure proper, hassle-free installation

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
  • If your brake booster is not working, nothing will happen or the brake pedal will push back against your foot
