A brake booster is a vacuum assist system that helps you push the brake pedal so that you can stop the vehicle. If you need to use more than normal pedal pressure to stop the vehicle and you need a longer distance to do so, your power brake booster is likely failing. Shop for your brake booster for GMC Sierra online and choose Same Day Store Pickup (in most cases) or Free Shipping when you purchase $75 or more. Our consistent staff helps you choose a Sierra power brake booster and the Loan-a-Tool Program has specialty automotive tools you can borrow.
