Combination Valve Disc/ Disc

The Combination Valve Disc/Disc from Allstar Performance is a critical brake system component engineered for dual-disc brake configurations. Designed for automotive enthusiasts and professional builders, this brass combination valve serves as the proportioning and metering hub in modern braking systems, where independent front and rear disc brake circuits demand precise fluid pressure control. This valve is essential for vehicles transitioning from drum brakes to full disc setups or for those requiring optimized brake balance during performance upgrades.

Constructed from durable brass in natural finish, the Combination Valve Disc/Disc combines proportioning, metering, and residual pressure functions in a single compact assembly. The dual-disc configuration allows independent control of front and rear disc brake pressure, preventing rear-wheel lockup and distributing braking force according to weight transfer dynamics. The brass construction resists corrosion and thermal stress while maintaining precise valve tolerances that regulate hydraulic pressure across both circuits. This integrated design eliminates the need for multiple separate valves, reducing plumbing complexity and potential leak points in the brake system.

This valve benefits street rods, custom vehicles, and performance builds requiring full disc brake systems with balanced front-to-rear pressure distribution. Installation typically occurs on the master cylinder outlet or proportioning block in the brake line circuit. Compatibility depends on matching the valve's port configurations and residual pressure ratings to your specific master cylinder output and brake caliper requirements; consult your brake system schematic or builder's guide to confirm fitment. The compact 5.5 x 1.15 x 9.05-inch footprint allows flexible mounting in tight engine bays common to restoration and custom builds.
