1-Inch Bore Cast Iron Master Cylinder

The Right Stuff DBMC05 is a cast iron master cylinder specifically engineered for vehicles equipped with disc brakes on both the front and rear (disc/disc) systems. This new master cylinder, featuring a 1-inch bore size, ensures robust hydraulic pressure for effective braking. It is designed as a direct replacement with a 9/16"-18 IFF outlet fitting and a dual bail, dual reservoir design. Constructed from durable cast iron, this master cylinder is built to withstand the demanding environment of a braking system and provide reliable performance for years. The Right Stuff emphasizes that their master cylinders are completely new units, eliminating the need for a core charge, which simplifies the purchasing and installation process. This master cylinder is designed for fitment across a range of GM vehicles from the late 1960s through the early 1970s, including models like the 1967-1969 Chevy Camaro, 1967-1972 Chevy Chevelle, and 1967-1970 Chevy C10/GM Trucks. It is also noted to be compatible with specific 1985-1986 Chevrolet C10 models with the 4.3L 262Cu. In. GM V6 GAS engine. However, it is explicitly stated that the DBMC05 does not fit a 1983 CJ7.
