Product Description
The 12000X Remanufactured Hydraulic Brake Master Cylinder is designed for medium- and heavy-duty commercial vehicles equipped with hydraulic braking systems using Bendix/Delco Hy-Power or Dual Power brake assist.
This master cylinder features a 1-3/4-inch bore and converts booster and pedal force into hydraulic pressure for the vehicle’s service brake system. The 12000X was used in a variety of older Chevrolet/GMC forward-control, conventional, and school-bus chassis, as well as International/Navistar commercial truck configurations.
Because several commercial master cylinders from this period have similar housings but different bore sizes, port configurations, reservoirs, and brake-system combinations, verify the original part number, bore size, hydraulic connections, and mounting arrangement before ordering.
