Product details
A 0.81-inch rotor-width specification and 1.38/1.38-inch piston bores identify this Wilwood Dynalite-M brake caliper. The anodized finish is applied to the exact component described below; match the mounting bracket before replacement. The four-piston Dynalite-M has a forged body shaped to improve outboard clearance and is used in Wilwood Classic Style assemblies. Match the exact mounting geometry and rotor sweep rather than treating every Dynalite model as interchangeable. The Wilwood disc brake range is designed and manufactured for motorsport, street-performance and specialized applications. It includes brake lines, fittings, valves and master cylinders together with calipers and brake rotors. Wilwood Engineering was founded in 1977 by Bill Wood and is based in Camarillo, California; its components must be matched to the complete braking system.

Fitment & Compatibility
This caliper requires the measured 0.81-inch rotor-width configuration and the matching lug bracket on 5.25-inch centers. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Confirm the 1/8-27 NPT hydraulic inlet, pad outline and total piston area with the rest of the brake system before assembly.
