W6A Radial Mount-Quick-Silver

Quick-Silver series W6AR nickel plated forged billet six piston calipers deliver heavy duty stopping power and reliability for the road or track. W6AR calipers incorporate race technology into a radial mount body design with widespread adaptability and an expanded rotor compatibility range from 12.19” to 15.00”, including update options for all W6AR Big Brake kits. Stainless steel pistons, high-temp seals, SRS bridge plates, and two-piece bleed screw assemblies are standard in all calipers. Two high performance street, and four high-temp race only brake pad compounds in the 6617 pad type, allow precise tuning of the brake response, friction requirements and temperature range for all types of high performance and competition applications.

The W6A 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.

The performance of the W6A 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.
