Arguably one of the most vital components in vehicles, a master cylinder is an integral part of the brake system. It plays the role of converting the force applied by the driver's foot on the brake pedal into proportional hydraulic pressure required to slow down or stop the vehicle. Modern brake system features two separate circuits, each controlling two wheels, providing a certain level of safety in case of failure of one circuit. Brake fluid is contained in a reservoir located under the hood. BMWs offer a high level of safety, however, failures of the brake system may happen anyway, as no machine has immunity from such malfunctions. But if you make regular maintenance properly, you reduce this risk to a minimum.
Substantially, the master cylinder is a cast iron or aluminum cylinder that houses a system of pistons and springs. When the brake pedal is pressed, a linkage transmits force to the pistons that compress brake fluid, which in turn transfers pressure required to perform braking. Sealing of the system is paramount, as even a small leak can result in a poor braking action, with dangerous and dramatic consequences. Browse our online catalog to choose from high-quality and reasonably priced BMW 3-Series brake master cylinders, reservoirs, and related components such as grommets, caps, and seals.
