Product Description
The HBS Electric Hydraulic Power Brake Booster Assembly combines an electric power brake booster and master cylinder to deliver reliable braking performance for vehicles with low engine vacuum, such as those with turbochargers, superchargers, or large lift camshafts. This assembly operates using a 12V electric pump, which can be mounted remotely and draws only 14 amps at maximum pressure, making it quieter than most performance fuel pumps.
Its compact design (7″ L x 5″ W x 8″ H) allows easy installation in classic cars, muscle cars, and street rods where space is limited. The system includes a hydraulic accumulator ball that stores pressure for smooth brake actuation and provides backup assistance in case of electrical failure. With a 1 3/16″ bore master cylinder, it generates 1600-1800 psi during regular operation and over 2000 psi at maximum output, ensuring compatibility with multi-piston calipers. HBS offers OEM/ODM services, low MOQ, and free samples for brake parts wholesalers and distributors seeking high-quality electric brake booster kits.
