Master Cylinders

A1 Cardone Master Cylinders

Master cylinders are control devices that convert brake peddle pressure into hydraulic pressure. The master cylinder controls wheel cylinders located at the other end of the system in the brake calipers and/or drum brakes. The wheel cylinders push brake pads towards the surface of either the drum or disc rotor, causing friction and ultimately bringing the wheel to a stop.

Piston bore wear and piston seal failure are the most common problems that occur in master cylinders. The most common symptom of a failing master cylinder is a brake pedal that slowly sinks under pressure. The cure for this is to replace the master cylinder.
