Summit Racing™ Power Brake Boosters

A Summit Racing™ power brake booster is the perfect addition to your street rod or custom application. The boosters use vacuum from the engine, or a standalone pump, to assist in slowing down the vehicle as you depress the brakes. This makes the brake pedal much easier to press and improves the braking response of the vehicle. These power brake boosters are available in multiple diameters, in single or dual-diaphragm designs to best fit your application. Choose between the brake booster only; or the brake booster and brake pedal rod extension kit, which makes installation even easier.

The Right Stuff Delco-Moraine Correct Brake Boosters

GM bolted 11 in. Delco-Moraine brake boosters to a bunch of its cars and trucks from 1967 to the early 1970s. Some cars came with "Delco-Moraine" stamped upside down on the front of the booster housing, while others were stamped the "proper" way. Still others were not stamped at all. No one can say with certainty which is "correct" for a specific car or model year, so The Right Stuff decided to make two versions of the Delco-Moraine booster--one with the upside-down stamp, one with the stamp right-side up. Pick the version you think was factory-correct for your car. Either way, you're getting a booster that looks and functions as The General intended. These boosters are officially licensed by General Motors, so they're factory-correct from the cadmium plating to the orientation of the Delco-Moraine stamp. And since the boosters are all-new, you'll have a reliable source of vacuum assist for your power brakes.
