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

The Wilwood 120-8727 Powerlite Radial Mount Brake Caliper is a four-piston disc brake caliper built for sports, rally, and off-road driving applications. It has a sleek profile and is lightweight, strong, and durable in higher-temperature situations. The Powerlite line starts at 2.26 pounds.

Key Features:

• Stress-flow forged body: Forging re-aligns the metal's grain structure to follow the contour of the caliper body. This avoids the interruptions to the internal grain that occur when machining a straight block billet.
• Radial transition design: The FEA-generated design removes steps and shoulders between the piston housing body and the caliper bridges. The radius in this area increases resistance to deflection and caliper separation under load.
• 7912 type brake pads: The pads are supported from the top by Quick-clip pad retainers. This removes the need for a pad support step in the bottom of the caliper and gives extra clearance for mounting closer to the hub on small wheel and rotor applications.
• Rotor and wheel range: The pad radius matches rotor diameters from 9.45" (240.0 mm) to 11.75" (298.5 mm). The caliper fits inside many 13.00" (330.2 mm) wheel applications.
• Easy pad access: The Quick-Clips let you reach the pads without removing the caliper. Pad compounds are available for the full range of sport and competition use.
• SRS stainless steel bridge plates: These eliminate bridge wear caused by pad gouging. Their spring-loading action also reduces pad rattle and dampens vibration harmonics that contribute to squeal under braking.
• Internal fluid passages: No external tubes are needed.
• Four corner bleed screws: They allow simple, effective air evacuation and let one caliper be mounted in any of four positions.

Radial mounting simplifies service. Wilwood bracket kits install the calipers in place of most lug mount calipers and provide two planes of adjustment for precise alignment over the disc. These bracket kits include the radial mount bracket, studs, locknuts, and caliper alignment shims.
