GM LH Metric Caliper

The GM LH Metric Caliper by AFCO Racing Products is a driver-side brake caliper engineered for General Motors vehicles equipped with metric brake systems. Designed for serious boaters and anglers who rely on properly maintained trailer brakes—or for any enthusiast maintaining a high-performance marine or automotive application—this caliper ensures consistent, reliable stopping power when it matters most. Whether you're launching at the ramp in challenging conditions or towing valuable equipment, brake system integrity directly impacts safety and control.

This metric caliper features a single-piston design with a 2.500-inch bore, delivering predictable hydraulic braking force across a range of operating conditions. Constructed from cast iron with a gray finish, it accommodates rotors up to 1.25 inches thick and mounts via a 5.500-inch floating bracket system, allowing thermal expansion and maintaining even pad wear. The one-piston configuration reduces complexity while maintaining the stopping capacity required for trailers and lighter performance vehicles, making it a practical replacement for worn or damaged units.

Owners of GM metric brake systems—particularly those towing boats, utility trailers, or vintage vehicles—will find this replacement caliper essential for maintaining factory brake performance. Installation requires matching it to the correct rotor thickness and confirming compatibility with your vehicle's brake line routing and caliper mounting points. At 6.93 pounds, it is a direct replacement component best installed by experienced technicians or those familiar with brake system service, ensuring proper bleeding and pad seating before returning to the water or road.
