Bendix/Delco-Moraine Dual Piston

Bendix and Delco-Moraine cast iron tandem dual piston master cylinders are single casting type with front and rear pistons and a separate reservoir and outlet for each piston.

Primary piston is operated by push rod connected to brake pedal. Secondary piston is operated by primary piston. In a combination disc and drum system, reservoir which feeds disc brakes is larger to compensate for larger displacement of disc caliper cylinder.
