When compared to open bridge calipers that use tube or stand spacers between the body halves, the closed end bridge design is measurably stronger with less separation or deflection under load. Additional strength and resistance to deflection comes from the four high-strength steel end bridge bolts.A fifth center bridge bolt provides even more overall strength and easy access to the pads without the need to remove the caliper from the mount. A unique six-piston differential bore configuration provides balanced loading for even pad wear in sustained high heat environments. The standard SL6 calipers feature one-piece stainless steel pistons.
Stainless is used for its slow heat transfer properties and high resistance to corrosion. The SL6/ST models feature Wilwood's exclusive Thermlock® pistons. This multi-part piston design creates a highly efficient thermal barrier to further reduce heat transfer from the pads to the caliper body, seals, and fluid. Cooler temperatures translate to longer service life and less chance for heat induced pedal fade. In addition, each SL6 is equipped with SRS bridge plates.
SRS plates eliminate all bridge wear caused by pad gouging and extend the service life of the caliper. The spring-loaded action of the SRS plates also eliminates pad rattle and dampens the harmonic vibrations that contribute to pad squeal. Two piece bleed screws and dampened fluid tubes are recess mounted to shield them from track debris and other potential damage sources.
High temperature, square faced bore seals provide the largest possible sealing area and controlled piston retraction on release. The full range of Wilwood pad compounds is available to match the brake response and heat range of any competition or sports driving application.
Calipers in this group feature a reduced width outboard body to provide additional clearance between the caliper face and the wheel or hub. These calipers were originally built for use with wide 5 hubs, but have found their way to other close fit wheel and hub applications. The caliper bridge radius will clear rotors from 11.75" to 13.00" in overall diameter. Each caliper in this group uses 7420 type 20mm thick pads.
