Wilwood HV Tandem Master Cylinder Kit with Combination Proportioning Valve and Mounting Hardware - 1 1/8 Inch Bore in Black
Description

The Wilwood HV Tandem Master Cylinder Kit offers a high-performance solution for custom brake systems, combining the popular aluminum tandem chamber master cylinder with a precision-proportioning valve, mounting bracket, stainless steel fluid lines, and hardware for a seamless installation. Designed for ease of use, this kit features a slotted flange mounting pattern compatible with many OE applications, including Chrysler, Corvette, GM, and Ford Mustang bolt patterns, making it suitable for both manual and power brake systems. The 1-1/8 inch bore size provides optimal pressure for a variety of vehicle setups, and the aluminum construction ensures durability and lightweight performance.
The included combination proportioning valve simplifies brake system wiring and adjustment, maintaining full isolation between the front and rear circuits to enhance braking efficiency and safety. Its black E-coat finish not only offers a sleek, performance-oriented appearance but also provides corrosion resistance for long-lasting durability. The stainless steel fluid tubes are pre-bent and include plated steel nuts, enabling quick, secure connections between the master cylinder and proportioning valve, while stainless steel button head fasteners ensure a rust-free, sturdy mount.
Installation is straightforward: connect the fluid lines, bleed the system, and you're ready for road testing. This kit is designed to be a direct bolt-on upgrade or replacement for many classic and modern vehicles, providing improved brake pressure control and reliability. Whether upgrading a performance vehicle or restoring a classic car, the Wilwood HV Tandem Master Cylinder kit offers a high-quality, durable solution that enhances overall braking performance and system longevity.
