Wilwood Powerlite Caliper 1.38in Pistons .790in/.860in Disc - Red

Note for Pistons, Rings, Rotors, Rods and engine internals

Unless otherwise specified, some brands supply brake rotors, pistons, strut mounts, rods and rings separately. In some cases, titles may indicate plural, or 'set' - eg the term “ring set” often refers to the rings for a single piston only.

CALIPER,POWERLITE,1.38/1.38,.79/.86

Powerlite 4-piston radial mount calipers combine pure race technology with a new generation of Wilwood performance enhancements. Their sleek profile, superior strength, and durability in higher temperature applications are easily adapted to a wide range of sports, rally, and off-road driving applications. The strength of the Powerlites is a combination of process and design. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper body. This eliminates the stresses and interruptions to the internal grain structure that occur when machining a straight block billet. Their FEA-generated radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridges. Incorporating a radius in this critical area substantially increases resistance to deflection and caliper separation under load. Structural deflection and volume displacement tests have proven the efficiency of this innovative design. Without even considering the overall greater strength and reliability of the billet forging, the reduction in overall deflection and fluid volume displacement translate into increased clamping efficiency with less pedal travel. The bottom line is a firm pedal with outstanding stopping power.
