Brake Master Cylinder

A brake master cylinder is a hydraulic cylinder that converts pressure (by a vehicles driver applying pressure to a brake pedal) into hydraulic pressure on the brake calipers or wheel cylinders. There are other forms of a brake master cylinder, such as a clutch slave cylinder - this device applies pressure to the clutch by the driver applying pressure to the clutch pedal. A master cylinder is usually made up of a fluid reservoir container, pistons, and the brake lines / hoses. When the brake pedal is depressed, the pistons move and apply pressure in the brake master cylinder or clutch slave cylinder. This pressure compresses the fluid evenly through brake line / hose and into the brake calipers / clutch. Additionally, engine vacuum is used to assist in applying pressure to the system though a brake booster. If a brake line were to fail, the master cylinder would redirect hydraulic pressure to the remaining lines, thereby eliminating failure of the brakes. Quality brake master cylinders for European and Asain vehicles - such as Audi BMW, Mercedes, Porsche, Volvo, Volkswagen, Honda, Acura, Nissan and more.
