Brake Booster is internal auto part of Chevrolet Astro, which helps to decrease the pressure for operating brakes of automobile. The brake booster makes use of a vacuum chamber that assists in increasing the hydraulic pressure out of the master cylinder and transferring it to the brake booster as per the force applied by means of the driver on the brake pedal. The boosters installed in Astro vehicles are primarily of two categories, they include vacuum operated boosters and hydraulic boosters. While vacuum boosters work with the differences of pressures between that of the engine vacuum and atmospheric pressures, hydraulic boosters work under fluid pressures for the application of the brake. These boosters are reasonably dependable but may sometimes merely stop working, hence having to be replaced. There are also after-market performance brake boosters and power brake conversion kits for more effective and easier to use braking mechanism.
