Aluminum Tandem Master Cylinder Kit with Bracket and Combination Valve – 1 Inch Bore – Chrome Powder Coat

Complete tandem master cylinder kit designed to simplify installation and setup of custom or upgraded brake systems. This package combines Wilwood’s aluminum tandem chamber master cylinder with a combination proportioning valve, mounting bracket, stainless steel fluid tubes, and mounting hardware to create a clean, bolt-on solution.

The tandem master cylinder uses dual hydraulic circuits and modern internal design for consistent brake pressure and precise fluid control. The slotted mounting flange allows straightforward installation on many common OE bolt patterns, including Chrysler, Corvette, GM, and Ford Mustang. The 1.00 inch bore size is suitable for both manual and power brake applications.

The included combination proportioning valve maintains full isolation between front and rear brake circuits while simplifying brake bias adjustment and brake light switch integration. Stainless steel fluid tubes are precision bent with preinstalled plated steel tube nuts for easy connection between the master cylinder and valve. Components are finished for durability and long-term corrosion resistance.
