Bendix Mini-Master Cylinder

Functions of the Bendix Mini-Master cylinder are basically the same as a conventional master cylinder although components differ.

When cylinder is in released position, primary and secondary actuators are in contact with compensating valve stems which project into cylinder bore.

This keeps valves off their seat and opens communication between cylinder bore and reservoir. The initial forward movement of piston permits compensating valves to seat. This closes communication between pressure chambers in cylinder bore and reservoir. As piston travels further, pressure build up is transmitted to calipers and wheel cylinders.
