Residual Pressure Valve 10Lb For Drum Brakes 1965-1973

Product Description

10lb. Residual Pressure Valve for 1965-1973 Mustangs with Drum Brakes.

These valves are used in a drum brake system to prevent air from being ingested into the hydraulic system when you release the brake pedal. Typical wheel cylinder seals only seal when there is pressure behind them. Rapid release of the brake pedal creates a vacuum in the system which causes the seals to relax and air is ingested into the wheel cylinders. Maintaining 10 PSI in the system at all times prevents this.

Does this proportioning valve replace original for drum brake 1967 big block

Asked by: Sebrof
This is not a proportioning valve and this will not replace the proportioning valve. This is a residual pressure valve that can be added to the brake lines after the proportioning valve.
