Product Details

As you depress the brake pedal, your pedal linkage causes a shaft to move forward in response to your foot, and as this shaft moves forward, it interacts with the brake booster and master cylinder. The brake booster contains a diaphragm that separates its interior into two parts, with both in a partial vacuum. As the brake pedal is depressed, it causes a valve inside the booster to open, which in turn allows air into one side of the booster. This difference in pressure on one side helps to push the piston inside the brake master cylinder forward in response to the brake pedal, which in turn slows and stops your vehicle. If your brakes are feeling soft then it may be a good idea to replace your brake booster.
