Wilwood Powerlite 4-Piston Brake Caliper, Gray Anodized, Part Number 120-8729

The Wilwood Powerlite brake caliper, part number 120-8729, is a compact, high-performance braking component designed for applications using an 11.00-inch outside-diameter rotor with a 0.860-inch rotor thickness. Its four-piston aluminum construction provides consistent clamping force and responsive braking performance while helping reduce unsprung weight compared with heavier caliper designs. The gray anodized finish adds corrosion resistance and a clean, professional appearance suitable for performance street, racing, and specialty vehicle builds.
The Powerlite caliper features a 5.08-inch radial mount configuration for secure installation and compatibility with properly matched braking systems. Its 1.38-inch pistons are engineered to deliver balanced pad pressure across the rotor, helping promote even pad wear and predictable pedal response. Because brake system compatibility depends on rotor specifications, mounting position, wheel clearance, and hydraulic requirements, verify the complete application before installation.
Wilwood part number 120-8729 is supplied as an individual brake caliper and is intended for use with compatible Wilwood components and properly selected brake hardware. Professional installation is recommended to ensure correct alignment, fastener torque, brake hose routing, fluid selection, and system bleeding. Whether used for a performance upgrade or a custom braking application, this Powerlite caliper offers a durable aluminum design and reliable four-piston braking capability in a compact package.
