  • 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’s Billet Dynalite Single utilizes close tolerance design and manufacturing techniques which results in the most rigid, lightweight and attractive caliper in the evolution of the Dynalite Single Series. Starting at 1.58 pounds, the Billet Dynalite Single is perfect for compact high performance braking as required in Open Wheel, Drag, Modified, Kart, Motorcycle and Off Road applications.

    • Lightweight, compact design with two stainless steel 1-3/4" pistons
    • Use with .38" rotors
    • Has 3-1/4" mount centers
    • Uses "Single Quick-Change" style pads

  • 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

    The Dyna Pro Single (DPS) billet caliper is the newest generation of calipers available as an upgrade or replacement for applications previously using the Dynalite Single (DLS) series. DPS calipers combine superior strength with performance enhancements to make these the best "Dyna" series calipers ever.

    The DPS is loaded with exclusive Wilwood performance enhancements. The calipers feature Quick-E-Clip pad retainers that support a 6812 type brake pad from the top. In addition to past pad service without caliper removal, the feature provides substantially stronger retention over the single Quick-Clip pin and 7012 type pads used in the previous DLS models.

    • Quick-E-Clip pad retainers supports brake pad from top
    • Heavy wall stainless steel pistons
    • Stainless steel SRS bridge plates eliminate pad rattle and dampen vibration
    • Internal fluid passages
    • Four corner bleed screws allow mounting in any front, rear, left, or right side position

    Wilwood 260-8419 Knob Style Proportioning Valve
    x
                

    This device lets you adjust the front-to-rear braking balance by proportionally decreasing the rear (or in some cases the front) brake line pressure. Can also be used to adjust individual front wheel braking in dirt track applications. Valve weighs only 5.2 ounces and has two .25" side mounting holes spaced 1.00" apart.

    • Allows easy adjustment of front to rear brake bias
    • Universal design works on all race cars
    • 100 to 1500 psi range, up to 57% pressure reduction
    • Accepts 1/8"-27 NPT fittings

    Compensates for weight transfer to the front wheels during braking. All factory brake systems allow for this in some fashion. An APV allows you to "fine tune" a street or race brake system and thus prevents severe rear brake lockup under moderate-to-heavy braking.

    Racer Note: Master cylinder bores are built with close tolerances. Stroking the master cylinder dry can cause damage to the internal rubber seals causing leaks, soft pedal, and lack of pressure. Never clean a master cylinder with carburetor cleaner or similar products as they will cause seal damage.

    Racer Note: When rebuilding brake master cylinders and calipers, always lubricate internal parts with brake assembly fluid before installation.
    This will keep seals and o-rings from becoming damaged by dry cylinder walls and pistons.

    The Forged Billet Dynalite is widely used in Road Race, Late Model Dirt, and Open Wheel motorsports. The latest applied developments and innovations in caliper design and manufacturing processes have resulted in substantial improvements in strength and performance over all comparable models.

    Forged Dynalites are the strongest calipers in the class, with weights starting at 2.80 pounds. Without even considering the overall greater strength and reliability of the forging, the reduced deflection tendencies and the resulting decrease in fluid volume displacement translate to increased clamping efficiency with less pedal travel. The bottom line is a taller pedal and better stopping power.

    • Pistion Count: 4
    • Area (in²): 4.80
    • Piston Type: Stainless
    • Fits .75" - 0.81" wide by 10" - 13.06" diameter rotors
