Wilwood 120-8724 Powerlite Four Piston Radial Mount Brake Caliper

The Wilwood Powerlite four-piston radial mount disc brake caliper combines exceptional strength with lightweight construction, starting at just 2.26 pounds. Engineered for superior performance in higher temperature situations, this caliper features a sleek, low-profile design that adapts easily to a wide range of sports, rally, and off-road driving applications.

Advanced Engineering and Construction:

• Stress-Flow Forged Body: The forging process re-aligns the metal's grain structure within the caliper body contour, eliminating internal stresses and grain interruptions that occur with traditional billet machining
• FEA-Generated Radial Transition Design: Eliminates steps and shoulders between the piston housing and caliper bridges, incorporating a radius that substantially increases resistance to deflection and caliper separation under load
• Type 7912 Brake Pad Design: Features top-supported pads with Quick-Clip retainers, eliminating the need for a bottom pad support step and providing additional clearance for mounting closer to the hub on small wheel applications

Key Features and Benefits:

• Compatible with rotor diameters between 9.45" (240mm) and 11.75" (298.5mm)
• Fits easily inside many 13.00" (330.2mm) wheel applications
• Quick-Clip retainers allow easy pad access without caliper removal
• SRS stainless steel bridge plates eliminate bridge wear from pad gouging and prevent pad rattle
• Spring-loaded SRS plates dampen vibration harmonics that contribute to brake squeal
• Internal fluid passages eliminate external tube requirements
• Four corner bleed screws enable simple air evacuation and allow mounting in four different positions

Installation and Adjustment:

• Radial mounting design simplifies service and provides two planes of adjustment for precise disc alignment
• Bracket kits available to replace most lug mount calipers (sold separately)
• Bracket kits include radial mount bracket, studs, locknuts, and caliper alignment shims

Brake pad compounds are available for the full range of sport and competition applications, making the Powerlite caliper a versatile choice for performance braking systems.
