Wilwood Residual Pressure Valve 10 PSI Drum Brakes

This is the red one, built specifically for drum brake systems. It maintains a steady 10 psi in the brake lines to keep those shoes close to the drums, giving you a firmer pedal and faster response every time you stomp it.

Perfect for setups where the master cylinder sits lower than the wheels or when you’re just sick of mushy pedal feel. Keeps fluid in the lines, air out, and confidence high.

Color-coded. Track-proven. Zero nonsense.

Plumb it. Forget it. Stop like you mean it.
