The Brake Booster is installed in Chevrolet Corvette automobiles to supplement the braking systems hence reduce the amount of force required by the driver. Sitting in between the brake pedal and the master cylinder it uses vacuum or hydraulic system to increase the force exerted while braking. There are vacuum-operated boosters which utilizes the engine vacuum to produce this pressure difference, and hydraulic boosters that utilizes the hydraulic fluid from the power steering or an electric pump to produce pressure difference. Chevrolet Corvette over the years have fitted different styles of brake boosters which include single and Dual Diaphragm and varying in diameter and polished or not. Usually, boosters with a larger diameter give more help, but there is also dual diaphragm boosters, which can offer comparable assistances in the confined space of an engine box. This versatility makes it possible for Corvette owners who may be working on a restoration or just updating a Corvette for today's use to apply the braking systems that will suit each vehicle appropriately.
