Details

These Aluminum Tandem Chamber Master Cylinder kit from Wilwood comes with a Combination Proportioning Valve, mounting bracket, fluid tubes and mounting hardware. The Tandem Master Cylinder represents the latest in refinements in brake pressure actuation and fluid control. The slotted flange mounting makes it a simple bolt on for many OE mounts including the popular Chrysler, Corvette, GM, and Ford Mustang bolt patterns and is compatible with manual or power brake system applications. Master cylinders are available with a 1-1/8” bore size and they come in your choice of standard, ball burnished, or black E-coat finishes.

The combination proportioning valve substantially simplifies wiring and brake proportioning adjustments on vehicles with custom brake systems. The combination block maintains full isolation between front and rear fluid circuits and is specifically designed to accompany the Tandem Chamber Master Cylinder. The combo valve and bracket are black E-coated for a performance look and long lasting durability. Stainless steel fluid tubes are precision bent with preinstalled stainless tube nuts for a simple bolt-on installation between the Combination Proportioning Valve and the Wilwood Tandem Master Cylinder. Stainless steel button head fasteners thread into the bracket for a simple installation and years of durable, rust-free performance. Simply connect the fluid lines, bleed the system, and you're finished.
