Overview

The ACDelco Power Brake Booster is a GM Original Equipment part designed, engineered, and tested to rigorous standards. These boosters multiply brake pedal force, applying additional force to the master cylinder for increased braking power. As true OE parts, they are either installed during GM vehicle production or validated by General Motors.

Engineered and tested to rigorous GM standards, this booster acts as a force multiplier, transmitting additional force to the master cylinder to enhance your braking capabilities. This vacuum-activated booster features a single diaphragm and a 10.53-inch diameter. As a genuine ACDelco GM Original Equipment part, it ensures compatibility and the same quality, reliability, and durability as the component originally installed in your vehicle. Some ACDelco GM Original Equipment parts may have previously been known as GM Genuine Parts (OE) or ACDelco Professional. This power brake booster is compatible with a range of Cadillac, Chevrolet, and GMC models from 2014-2020, including specific trims and engine options such as the 6.2L V8 engines in the Cadillac Escalade and Chevrolet Tahoe, as well as the 5.3L V8 engines in the Chevrolet Silverado 1500 and GMC Sierra 1500. The manufacturer provides a minimum 12-month warranty for this part. Currently, this product is listed as 'No Longer Available For Purchase' on TascaParts.com.
