Bracket Kit Prop Valve Diecast Master Cylinder

The Bracket Kit Prop Valve Diecast Master Cylinder from Wilwood is a critical hydraulic component designed for custom and high-performance brake system builds. This bracket kit serves as the structural foundation for proportioning valve integration, allowing you to mount a prop valve directly to your diecast master cylinder assembly. Whether you're upgrading a street rod, restoring a classic muscle car, or engineering a track-focused brake package, this kit eliminates the need for external mounting solutions and delivers a clean, factory-style installation that maximizes underhood real estate.

Manufactured from precision diecast materials, the bracket kit features engineered geometry that securely indexes the proportioning valve to the master cylinder body without machining or drilling modifications. The compact design—measuring just 5.35 by 6.15 inches—fits within tight engine compartments while maintaining full access to adjustment and bleed ports. Wilwood's diecast construction provides rigidity necessary for repeat brake cycling and vibration resistance, while the lightweight profile (0.48 lbs) adds negligible mass to your braking system. This integration approach simplifies plumbing runs and reduces pressure line lengths, improving brake feel and response time across front-to-rear brake bias tuning.

Mechanics and enthusiasts building dual-reservoir or bias-adjustable brake systems will find this bracket kit essential for organizing modern proportioning valve setups on classic platforms. It's compatible with Wilwood diecast master cylinders and works in conjunction with prop valves for independent front and rear brake line pressure management—a necessity when upgrading disc brakes to lighter, performance-oriented platforms. Installation requires no welding; simply bolt the bracket to the master cylinder and secure your prop valve assembly. This kit is ideal for hot rod builders, vintage race car preppers, and anyone standardizing on Wilwood's integrated brake architecture for reliability and adjustability.
