Info

The W4A/ST forged four piston caliper delivers heavy duty stopping power for the road or track. The caliper incorporates race technology into a body design with widespread adaptability. Radial mounting, two options for piston volume, and a rotor diameter ranging from 12.19" to 14.25" give this caliper the versatility necessary to suit all types of heavy weight braking requirements. The W4A/ST body is the product of FEA computer design and stress flow forging technology. FEA technology allows the designer to test the prototype in a computer environment to determine the optimal structural design within the dimensional parameters of the component. Stress flow forging produces a part with the internal grain structure of the metal aligned in the direction of the flow of the body contour. The results are a caliper with superior clamping efficiency and ultimate strength against fatigue, stresses, and distortion under load. This caliper generates big brake clamping force with six differential bore stainless steel pistons. Stainless steel is used for its high resistance to corrosion and low thermal conductivity that reduces the heat transfer from the pads. The differential bore pattern balances pad loading to help maintain even pad wear. High temperature bore seals provide long service life and maintain their resilience to provide positive piston retraction on release. Two options for overall piston volume make it simple to match the calipers with master cylinder output and rear caliper size for correct bias proportioning. The performance of the W4A/ST is enhanced with SRS bridge plates, snap-ring locked pad retainer pins, recessed two-piece bleed screw assemblies and dampen mounted fluid transfer tubes. SRS bridge plates eliminate all bridge wear caused by pad gouging. The spring-loaded action of the plates also eliminates pad rattle. Snap ring clips lock the pad pins in place to provide positive retention and allow easy service without caliper removal. The bleed screws are recess mounted for protection against impact and debris. The fluid tubes are dampen mounted to protect them from fatigue or damage from vibration or debris. Calipers are anodized in high luster black to protect from corrosion and maintain their high-tech appearance. The W4A/ST is also available with a gloss red finish or other custom Wilwood color by order. Radial mount adapter brackets are used in Wilwood brake kits to provide a secure and precise method of attaching the W4A/ST caliper to the factory mount bosses on the original spindle.

  • We get a lot of questions about brake kits so Tim gives a brief overview of disc brake setups.
  • If you're changing your brake pads before you hit your first race, it's important to burnish or bed-in your new pads. Check out our quick tech-tip on bedding brakes and how to minimize pad wear and get the best performance out of your brakes.
  • After getting the control arms and drop spindles installed last time, we are dying to see what it looks like on the ground. Today we are working with the Speedway Deluxe Disc Brake Kit. Josh and Joe are on a roll!
