Speedway Disc Brake Residual Valve, 2 PSI, Purple
Speedway Disc Brake Residual Valve, 2 PSI, Purple
x
            

Ever had problems with a spongy pedal or slow, unresponsive brakes? If so, you may need a residual pressure valve installed in your brake line. A residual valve acts like a one-way or check valve to maintain brake system pressure to eliminate the problems of a spongy pedal. This 2 PSI residual valve is installed inline between the master cylinder and disc brake calipers to keep 2 PSI of residual pressure at the caliper after the brake pedal is released. This ensures that you will have a high, firm pedal next time you press the brake pedal.

If your master cylinder is located below the floorboard, installing a 2 PSI residual valve is highly recommended. If your master cylinder is mounted on the firewall, a residual valve is generally not needed because gravity will provide a natural residual pressure within the brake line.

Our residual pressure valve features a distinctive purple anodized finish with 1/8" NPT port at each end. Use 2 PSI residual valves for disc brake applications only.

Wilwood High Volume Aluminum Master Cylinder
Wilwood High Volume Aluminum Master Cylinder
x
            

Wilwood high-volume aluminum master cylinders have the highest fluid capacity of any integral reservoir design. With a total capacity of 8.2 ounces, there is at least 26% more fluid than most competitive brands. More fluid volume means cooler temperatures and additional insurance for extreme conditions where high pad wear can compromise fluid levels during long events. With 1-7/16" of piston travel, there is plenty of margin when used with large four or six piston calipers.

An internal slosh baffle guarantees a constant fluid supply to the bore chamber during hard cornering, acceleration and braking. This unique baffle also eliminates aeration into the reservoir from return fluid that can occur during brake release and bleeding procedures.

  • Die-cast from high-grade aluminum
  • Heavy-duty internal piston springs provide fast retraction for immediate release and positive fluid transfer without the need for cumbersome external pushrod springs
  • Pedal feel is improved, piston retraction is guaranteed, fluid recovery is quicker and the bleeding process is simplified
  • Formed steel lids, heavyweight bail wires and bellows type gaskets keep the fluid in and the moisture out with correct pressure balancing during fluid displacement
  • 1/8"-27 NPT fluid port
