Wilwood 120-8727-BK Powerlite 4-Piston Radial Mount Brake Caliper

The Wilwood Powerlite four-piston radial mount caliper delivers exceptional performance in a lightweight, compact package starting at just 2.26 pounds. Engineered for superior strength and durability in high-temperature situations, this caliper is easily adapted to a wide range of sports, rally, and off-road driving applications.

Advanced Stress-Flow Forging Technology:

Strength comes from a combination of advanced manufacturing process and intelligent design. The stress-flow forging process re-aligns the metal's grain structure within the contour of the caliper body, eliminating the internal stresses and grain structure interruptions that occur when machining from straight block billet. The FEA-generated radial transition design eliminates steps and shoulders in the critical area between the piston housing body and the caliper bridges, incorporating a radius that substantially increases resistance to deflection and caliper separation under load.

Quick-Clip Pad Retention System:

The Powerlite utilizes the new 7912 type brake pad that is supported from the top by Quick-Clip pad retainers. This innovative design eliminates the need for a pad support step in the bottom of the caliper, adding additional clearance for mounting closer to the hub on small wheel and rotor applications. The Quick-Clips also allow easy pad access without caliper removal for faster service.
