Brake Booster Replacement Cost
Brake Booster Replacement Estimate (National Average)
We recommend using an OEM factory quality brake booster replacement part and verifying that the brake master cylinder is not leaking any brake fluid. Leaking brake fluid can work its way into the brake booster housing and cause the new brake booster to fail prematurely.
When a brake booster is defective, the effort required to stop the vehicle may increase significantly and the vehicle may idle roughly. Also, there may be a loss of vacuum, which is necessary to operate other systems such as heating, ventilation, air conditioning, and cruise control.
The Check Engine Light may illuminate with a P0171 or P0174 code, which indicates that the fuel system is running too lean due to a vacuum leak in the brake booster.
Excessive brake pedal stopping effort is not always caused by a defective brake booster. It can also be caused by engine vacuum leaks, glazed brake rotors and drums, very hard brake pads and shoes, or sticking, rusty disc brake calipers and drum brake components.
