Powerlite Radial Mount 4-Piston Caliper – Red Powder Coat

The Powerlite Radial Mount caliper is engineered for sports, rally, and off-road driving enthusiasts seeking lightweight performance and reliable stopping power. Weighing just 2.8 lbs, this caliper features a forged aluminum body for superior strength and durability under high temperatures.

The four stainless steel pistons provide a total piston area of 3.00 in², ensuring consistent clamping force. The caliper is designed with a stress-flow forging process, aligning the metal's grain structure for improved resistance to deflection and separation under load. The FEA-optimized radial transition design eliminates steps and shoulders between the piston housing and caliper bridges, further increasing rigidity.

The Powerlite uses the 7912-type brake pad, supported by Quick-clip pad retainers for easy pad changes without caliper removal. The pad area is 5 in² with a volume of 1.8 in³, compatible with rotor diameters from 9.45" (240 mm) to 11.75" (298.5 mm) and rotor widths from 0.79" to 0.86". The caliper fits most 13.00" (330.2 mm) wheel applications.
