About this product

GM Genuine Parts Brake Boosters with Brake Master Cylinders are designed, engineered, and tested to rigorous standards, and are backed by General Motors. The brake booster and the brake master cylinder work together to help the driver stop the vehicle. The master cylinder stores brake fluid that is pushed through the lines and forces the brake pads against the disc when the brakes are engaged, helping to slow the vehicle. GM Genuine Parts are the true OE parts installed during the production or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
