Many British road cars in the 1950s through the 80s were equipped with Girling master cylinders as original equipment. These high-quality units were quickly adopted by race car constructors. Girling masters are still preferred for new construction because of their compact size and unmatched reliability.
These genuine Girling master cylinders are designed to accept a remote fluid reservoir (sold separately). The outet port faces the rear of the car, which is ideal for cars with limited space in front of the master cylinder. The lengths of the pushrod (included) vary but are usually 3.75 to 4.00" long as measured from the mounting flange. These single-circuit masters can be used for either clutch or brakes. Sold individually.
