Wilwood 120-8726 Powerlite Radial Mount Brake Caliper - 4-Piston

The Wilwood Powerlite four-piston radial mount caliper delivers exceptional performance in a lightweight, durable package. Starting at just 2.26 pounds, this caliper features a sleek profile and superior strength, making it ideal for sports, rally, and off-road driving applications where high temperatures and demanding conditions are common.

Advanced Engineering and Construction:

• Stress-Flow Forged Design: The forging process re-aligns the metal's grain structure within the caliper body contour, eliminating internal stresses and interruptions that occur with straight block billet machining
• FEA-Optimized Radial Transition: Computer-generated design eliminates steps and shoulders between the piston housing and caliper bridges, substantially increasing resistance to deflection and separation under load
• Compact Profile: Designed to fit inside many 13.00-inch wheel applications with optimized clearance for mounting closer to the hub

Brake Pad System:

• Uses Wilwood Type 7912 brake pads with top-mounted Quick-Clip retainers for easy access without caliper removal
• Eliminates traditional pad support step in the caliper bottom, providing additional mounting clearance
• Pad radius compatible with rotor diameters from 9.45 inches (240mm) to 11.75 inches (298.5mm)
• Multiple compound options available for sport and competition applications

Premium Features:

• SRS Stainless Steel Bridge Plates: Eliminates bridge wear from pad gouging while the spring-loading action prevents pad rattle and dampens vibration harmonics that cause brake squeal
• Internal Fluid Passages: Clean, streamlined design eliminates the need for external brake lines
• Four-Corner Bleeder Screws: Allows simple and effective air evacuation and enables caliper mounting in any of four positions
• Radial Mounting System: Simplifies service and provides two planes of adjustment for precise disc alignment when used with bracket kits

Bracket kits are available for installation in place of most lug-mount calipers and include the radial mount bracket, mounting studs, locknuts, and caliper alignment shims.
