ACDelco GM Original Equipment Power Brake Boosters with Brake Master Cylinders are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These components work together to help the driver stop the vehicle. The brake booster uses a stored vacuum to overcome the high fluid pressure in the braking system, and allows the driver to not put as much pressure on the brake pedal to brake. The Master Cylinder stores brake fluid that is pushed through the lines and that forces the brake pads against the disc when pressure is forced on the brake pedal. ACDelco GM Original Equipment parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional.
