Remanufactured Power Brake Booster

Your power brake booster sits between the brake pedal and the master cylinder, using engine vacuum (or in some applications, hydraulic pressure from the power-steering system) to multiply the force you apply at the pedal. The result: a 200-lb hydraulic squeeze at the calipers from a 20-lb push at the pedal. Common failure symptoms include a hard pedal that requires excessive force to stop the vehicle, a hissing sound from under the dashboard, the engine stalling when you press the brakes hard, and a brake pedal that slowly sinks under steady foot pressure.

This unit is a new, OE-quality replacement booster. The diaphragm, return spring, internal valve, and pushrod are all factory-fresh components built to original-equipment specification. Each booster ships pressure-tested for vacuum hold and leak-free operation. Direct bolt-in for the vehicles listed in the fitment table — no modifications required.

Every Score Auto Parts component is covered by a 1-year warranty against defects in materials and workmanship from the date of purchase. Warranty is void if the part is installed on a vehicle not listed in the fitment table, or modified after purchase.

Returns accepted within 30 days for unopened, uninstalled parts. Core deposits are refunded upon receipt of your old part in rebuildable condition.
