Heavy Duty Solid Brass Brake Proportioning Valve For Disc Front Drum Rear Systems Adapts To Dual Reservoir Master Cylinders Built Tough For Chevy And Buick Trucks Delivers Hella Durable Knockout Stopping Power You Can Trust Every Single Mile

Solid brass proportioning valve for mixed front rear braking
✔️ Replaces most dual reservoir master cylinders Chevy Buick kits

This solid brass hydraulic component balances brake pressure across mixed front disc and rear drum axle configurations. Mechanics install it alongside dual reservoir master cylinders to prevent wheel lockup during hard stops. Drivers relying on vintage work trucks or performance builds get reliable stopping distance without overfilling the rear circuits.

✅ Accepts input lines of one half inch and seven sixteenth inch diameter
✅ Machined from corrosion resistant solid brass metal for long life
✅ Direct swap fitment matches factory chassis mounting holes perfectly
✅ Finished with a durable gold plating that resists road grime buildup

💡 What triggers the need for supplemental pressure regulation on mixed brake setups?

Balancing hydraulic force ensures tires grip pavement instead of sliding on rubber when you mash the pedal.
- Adjusts rear circuit fluid flow to match front disc friction characteristics
- Maintains consistent pedal travel while protecting rear axle components from heat fade
- Eliminates uneven weight transfer issues during sudden deceleration events
- Keeps suspension geometry stable under heavy towing or hauling loads
