Proportioning Valves and Accessories

Classic Performance Products offers a range of brake proportioning valves and accessories, ensuring the correct brake fluid pressure for your vehicle’s front and rear wheels. Available in both fixed and adjustable options, these valves are essential for drum-to-disc brake upgrades. Features include a warning light switch for detecting pressure loss and the ability to be wired into your system. Our valves handle four key functions: ... proportioning pressure, a 10 psi residual check valve, a metering valve for the rear brakes, and a brake warning light. Ideal for maintaining balanced brake performance and preventing rear drum brakes from locking up too easily, these valves are a crucial component for your classic car or truck's braking system.
