Aluminum Integral Master Cylinder with Small Reservoir 0.65 inch Bore
These master cylinders have been designed by OBP as a less-expensive alternative to the Girling brand. They have a small (1 3/4″ diameter) fluid reservoir built into the front of the casting. The outlet port faces the rear of the car, which is ideal for cars with limited space in front of the master cylinder. All sizes come complete with a pushrod. The pushrod measures 3.3″ long overall (approximately 3″ exposed from the mounting flange). These single-circuit masters have can be used for either clutch or brakes. The EPDM seals are formulated to work with any DOT-rated brake fluid (not for use with hydraulic oil). Sold individually.

Cylinder Length (measured from mounting face): 3.95″ (4.2″ including cap)
