Caliper Bracket Metric Clamp On

The Caliper Bracket Metric Clamp On (ALL 42185) is a heavy-duty rear brake caliper mounting solution engineered for GM-platform vehicles using metric brake systems. This component addresses a critical need in brake system assembly and upgrade work, serving mechanics, fabricators, and performance enthusiasts who require precise caliper positioning on 3-inch OD axle tubes. Whether rebuilding factory brake systems or upgrading to modern metric calipers, this bracket provides the structural foundation for safe, reliable braking performance.

Manufactured from steel and finished in durable black paint, the Caliper Bracket Metric Clamp On delivers the rigidity and corrosion resistance required for sustained brake duty. The clamp-on design eliminates welding, allowing installation without permanent frame modification—a critical advantage in restoration and retrofit applications where original geometry must be preserved. The bracket's geometry is optimized to work specifically with GM metric calipers, ensuring proper alignment and pad-to-rotor contact geometry that is essential for brake safety and longevity. At 2.96 lbs, the component adds minimal unsprung weight while maintaining the steel construction necessary for heat dissipation and structural integrity under sustained braking loads.

This bracket is ideal for technicians and builders working on GM vehicles equipped with 3-inch OD axle tubes transitioning to metric brake systems. Installation requires access to the axle tube and basic hand tools; the clamp-on mounting method ensures repeatability and adjustability. Proper torque specification and positioning against the axle tube are critical to prevent caliper drift during operation. Compatibility is limited to GM metric calipers and axles matching the specified 3-inch OD dimension, making verification before purchase essential to ensure correct fit and function.
