Alum Tandem M/C Kit w/ Brkt & Prop Valve 15/16

The Alum Tandem M/C Kit w/ Brkt & Prop Valve 15/16 from Wilwood is a complete master cylinder assembly designed for drivers building high-performance brake systems or upgrading aging hydraulic setups on street rods, race cars, and custom vehicles. This tandem master cylinder kit addresses the need for dual-circuit brake redundancy—a safety feature that isolates front and rear brake circuits so that a single line failure doesn't compromise complete braking.

Built from lightweight aluminum construction, the Wilwood tandem master cylinder reduces unsprung mass compared to cast iron alternatives, benefiting both handling responsiveness and fuel economy in weight-conscious builds. The 15/16-inch bore diameter is a proven midrange specification suited specifically for street and moderate-duty applications, offering smooth modulation without excessive pedal travel. The kit includes a mounting bracket and proportioning valve, allowing you to balance brake bias between front and rear circuits—critical for preventing lock-up and ensuring balanced deceleration across varying vehicle weights and load distributions.

Wilwood's engineering ensures precise tolerances and responsive valve actuation, translating foot pressure into predictable brake feel. This tandem master cylinder assembly is ideal for fabricating custom chassis or upgrading your street machine's stopping power, making it a versatile choice for various applications.
