CARDONE Reman Power Brake Booster P/N:54-74705

Push the pedal with less effort and firmer control using the A1 CARDONE brake booster, remanufactured vacuum power brake booster P/N 54-74705. It drops in as a direct-fit replacement for the 2003-2006 Ford Expedition and 2003-2006 Lincoln Navigator (see the Buyer's Guide tab for engine-level fitment). A brake booster uses engine vacuum to multiply the force your foot applies at the pedal, so if a leaking diaphragm or failed check valve in the original is behind a hard, high pedal, this reman unit replaces it.

Each CARDONE unit is reverse-engineered from decades of engineering experience, with original design weaknesses identified, corrected, and where applicable upgraded for added durability, then remanufactured to meet or exceed O.E. performance.

• Like-new internals: 100% O.E.-quality seals, diaphragms, and check valves are installed on every unit for reliable operation.
• Corrosion protection: an exclusive rust-prohibitive finishing process helps extend unit life.
• Faster install: master cylinder output rods are pre-adjusted when included, for easier setup.
• 100% tested: every unit is fully tested and backed by a guaranteed fit and function.

A worn booster may show a hard-to-press pedal, hissing under braking, or a stalling engine when you brake — signs this unit may need replacing.
