Wilwood 260-13190 Adjustable Proportioning Valve with Tandem Master Cylinder Mounting Bracket

The Wilwood 260-13190 proportioning valve kit is designed to help fine-tune rear brake pressure for improved braking balance and vehicle control. It includes a tandem master cylinder mounting bracket and an adjustable valve with a convenient knob-style pressure adjustment, making it well suited for performance street vehicles, race cars, and custom brake system installations.
The valve features 3/8-24 inverted flare female inlet and outlet ports for compatibility with commonly used brake lines and fittings. Its adjustable pressure range from 150 to 1,200 psi allows the braking system to be tailored to the vehicle, tire combination, driving conditions, and desired front-to-rear bias. Proper adjustment can help reduce premature rear-wheel lockup while maintaining effective braking performance.
Constructed from lightweight aluminum, the Wilwood proportioning valve is built for dependable service and straightforward installation. The included tandem master cylinder mounting bracket provides a practical mounting solution for compatible applications, while the compact kit design helps simplify brake system upgrades and custom builds. Always verify master cylinder, brake line, fitting, and vehicle compatibility before installation, and follow proper brake bleeding and adjustment procedures.
