Performance Machine Complete 2-Piston Springer Brake Caliper and Bracket Kit
The Performance Machine Complete 2-Piston Springer Brake Caliper and Bracket Kit is the definitive solution for riders who need high-performance stopping power without sacrificing custom style or space. Unlike competitors who often sell components separately, this is a 100% complete kit that includes the caliper, the specialized mounting bracket, and the anchor rod assembly. Engineered around the ultra-slim 125×2 series caliper, this setup provides a narrow-body profile that is specifically designed to fit in the tightest spatial envelopes, solving the common “spoke-to-leg” clearance issues found on narrow-glide springer front ends.
This universal kit is fully ambidextrous, allowing for seamless installation on either the left or right side of the hub. Precision CNC-machined from high-strength billet aluminum, the assembly uses a floating mount system that ensures the caliper stays perfectly aligned with the rotor throughout the suspension travel. Whether you are building a vintage-style bobber or a high-end custom chopper, this Performance Machine kit delivers a firm, predictable lever feel and the legendary “show-bike” finish the industry expects.

Installation and Fitment Notes
This kit is designed for use with 3/4 inch axles. Critical Technical Note: The included anchor rod utilizes 5/16 inch mounting hardware. Since many springer front end legs utilize a 3/8 inch mounting boss on the rear leg, a 3/8 inch to 5/16 inch stud adapter (sold separately) is typically required to properly secure the torque arm. This is a universal custom kit; it is not a direct “bolt-on” for OEM Harley-Davidson Springer models and will require custom spacing for factory applications.
