The Wilwood HV Tandem Master Cylinder Kit is a high-performance brake system component designed for custom and performance vehicle applications. This kit includes a tandem master cylinder with a 15/16-inch bore, a left-hand mounting bracket, and an integral proportioning valve—all the essential elements needed to upgrade or replace an existing brake master cylinder system.
The tandem design provides independent pressure control for front and rear brake circuits, a critical safety feature in modern brake systems. The proportioning valve regulates brake pressure distribution between circuits to optimize stopping power and prevent wheel lock-up. With the left-hand bracket mounting configuration and pushrod compatibility, this kit is engineered for straightforward installation in many custom brake applications. Wilwood's tandem master cylinders are trusted in performance and restoration projects where reliable brake modulation and system control are paramount.
