Upgrade Your GM Metric Disc Brake System with Our Powder Coated Calipers

GM’s Metric chassis (AKA 78-88 A- and G-Body, including Monte Carlo, Cutlass, and others) has become legendary. From using their chassis for circle track racing to many of their systems being integrated into aftermarket performance parts that allow people to easily find service parts at their closest auto parts store, GM’s Metric chassis lives on some three plus decades after the last one rolled off the assembly line!

The GM Metric chassis front and rear disc brake system components are a perfect example of what we mean. These pieces, like rotors and calipers are used for many an aftermarket disc brake conversion kit, allowing the consumer to easily find caliper slide bolts, brake pads, and more for a quick repair to get their ride back on the road. Speedway Motors offers numerous brake kits with GM Metric calipers as part of the kit for example. Traditionally, these GM Metric calipers have been a natural finish, but for those looking to create a statement with large window aftermarket wheels, we now offer these GM Metric calipers in both black and red powder coated finishes.

Direct Replacement Fitment for Your GM Metric Disc Brake System

Our powder coated GM Metric brake calipers are made from the same heavy-duty cast iron material as the originals and feature a large 2-3/8-inch piston for strong and consistent braking performance. The slide bolt mounting center-to-center distance of 5.45-inches is maintained to ensure trouble-free installation on your GM Metric pattern disc brake caliper mounting brackets. This allows you to upgrade your front disc brake kits with a GM Metric caliper in black or red powder coat for appearance purposes. These calipers can also be used for rear disc brake conversions designed for the GM Metric disc brake caliper that does not utilize an integral parking brake system.

Compatible with standard 11-inch to 11-3/4-inch diameter 1.00-inch-thick disc brake rotors, these GM Metric brake calipers will directly replace your current bare finish GM Metric calipers. For applications using .810-inch-thick rotors our disc brake pad spacer will ensure proper fitment. The caliper’s floating design requires a flexible brake hose connection, and we make that connection easy with a 7/16-20 SAE threaded fluid port that includes new crush washers for stress-free installation. If your brake lines aren’t already a 7/16-20 banjo end you may require new brake hoses. For those running AN -3 brake hoses our banjo bolt kit will get you all set up with the right connections. The bleeder screw maintains the OEM GM Metric 10-1.5MM spec, making it easy to find replacement bleeder screws.

Finished In a Deep Black or Bright Red Powder Coat Finish

Lastly, we can’t forget about one of the best reasons for upgrading your GM Metric calipers! We have added robust protection and the performance-oriented appearance of powder coating for your GM Metric-based disc brake system. Available in black or red gloss powder coat, you can add that great performance look behind those big-window custom wheels you have. Adding that little bit of color makes your disc brake system stand out. It certainly doesn’t hurt that the powder coated surface helps keep your GM Metric caliper upgrade looking good for many years to come through all manner of road dirt, rain, and other nastiness when driving. They easily clean up and look like new with your favorite wheel cleaning product that removes dirt and brake dust!

These calipers are sold individually by side and we recommend new caliper slide bolts that eliminate the factory style slide bolt bushing and provide less caliper flex. The included caliper piston and seal can take the abuse of racing (these calipers are powder coated versions of our IMCA approved GM Metric calipers, and as such can be used for those IMCA racing classes where allowed), which means you can run race ready or street-friendly D154 brake pads depending on your application needs. We offer a wide selection of D154 disc brake pads for racing and street use.
