Product Description
The Bendix 11993 Hydraulic Brake Master Cylinder is a heavy-duty mini master cylinder designed for medium-duty trucks and buses equipped with hydraulic braking systems.
The 11993 features a 1.75-inch bore and an 80 cubic-inch fluid reservoir. It converts brake pedal and booster force into hydraulic pressure for the service brake system and uses a dual-outlet design with a 9/16"-18 primary port and 1/2"-20 secondary port. This configuration does not use an internal residual check valve.
The 11993 was used on a variety of older GM/Chevrolet/GMC and International/Navistar medium-duty vehicles. Current interchange data connects it to Raybestos MC39528 and MC116702, Dorman M39528, Centric 130.82002, and Cardone 13-8001.
