Proportioning Valve
This solid brass proportioning valve is crafted for disc/drum brake systems and ensures the perfect brake bias between your front and rear brakes. It’s ideal for hot rods, classic trucks, and swapped vehicles, helping prevent rear-wheel lockup during hard braking.
Key Features:
- Solid brass construction for durability and corrosion resistance
- Designed for disc front / drum rear systems – automatic pressure adjustment to rear brakes
- Standard ports: ½″-20 master cylinder inlet and 7⁄16″-24 master cylinder inlet, with outlets sized for front (3⁄8″–24) and rear (9⁄16″–18) lines
- Universal fit – works with most dual-reservoir master cylinders
- Ideal for GM, Ford, Mopar street rods and truck builds
How It Works:
Under normal driving, the valve sends full pressure to all brakes. When pressure exceeds rear brake capability, it reduces fluid flow to the rear to prevent lockup—maintaining a safe, balanced stop .
What’s Included:
- (1) Brass proportioning valve (PV2 style)
- Pre-threaded ports for easy integration
- Mounting bracket and warning switch sold separately
Install Tip: Mount it close to the master cylinder and use correct fittings for your lines. This valve helps significantly improve stability under hard braking.
