CALIPER PISTON WW200-7551

Wilwood GN6 & SL4 Caliper Front and Rear Brake Caliper 

Thermlock® pistons provide the most effective thermal barrier available for minimizing heat transfer from the brake pads to the caliper body, seals and fluid. This innovative multi-part design incorporates a stainless steel shield and coated aluminum shell configuration that effectively retards heat transfer by at least 25 percent. This reduction in operating temperature eliminates seal crystallization and localized fluid boiling, which decreases distortion in the caliper body and piston bores, extending overall service life. This technology was originally developed for the extreme temperatures and sustained high heat in NASCAR and professional road racing brake systems. Thermlock® pistons are standard equipment in all Wilwood Racing caliper models, and are available as service replacements or upgrades in most current and older Wilwood calipers
