Overview

The Allstar Performance ALL42102 Metric Weld-On Caliper Bracket is built for rear GM metric caliper systems. It anchors the caliper to a 3 in diameter axle housing with precision and strength, supporting consistent braking behavior across street and light track use.

Durability and precision

Crafted from 1/4 in thick steel, this weld-on bracket resists flex and maintains caliper alignment under load. The robust construction helps maintain pad engagement and rotor clearance, contributing to predictable braking response and reliable service life in varied driving conditions.

Key specifications at a glance

  • Brackets fit 3 in diameter axle housings
  • Designed to work with 11.75 in diameter rotors

With GM metric caliper compatibility, this part slots into common rear brake configurations, offering a straightforward path for retrofits or upgrades while preserving existing rotor sizes where possible.

Materials, finish, and fit

  • Material: steel, natural finish
  • Finish: natural steel texture for ease of inspection and potential finishing

The weld-on design is intended for shop use with typical welding equipment. Proper welding and bolt pattern verification are essential for safe, long-term mounting. The bracket’s geometry is designed to align with the caliper mounting surface and rotor plane when paired with compatible components.

Real-world use scenarios

Ideal for retrofitting GM metric rear brake setups in classic builds, performance street cars, or small-bore race projects that utilize a 3 in axle tube. By locating the caliper at a consistent position relative to the rotor, it can help maintain even pad wear and balanced braking across wheels.

What you get

  • Rear brake caliper bracket, weld-on, steel, natural finish

Installation notes

Check caliper bolt patterns and ensure a clean weld during installation. While the bracket itself is compact, plan for proper alignment checks as part of your brake system assembly and testing routine.
