Having rules that specify specific parts, weights, dimensions, and more means everyone, theoretically, is running the same car with the same performance, making the race more about driver skill and race strategy. It is a great, cost effective, way to go racing while being competitive and having some fun. One such spec item the IMCA mandates for many of their racing classes, including Modifieds, Hobby Stock, and others, is the use of the ’78-’88 GM Metric caliper. Having the same caliper body and piston size as an approved IMCA part means everyone has the same braking system capability. The issue has been finding a good GM Metric caliper though. Parts store remans are iffy at best, often being remanufactured with substandard parts, and requiring core charges or turning in your old calipers. We opted to craft a brand new reproduction steel brake caliper that meets all the class rules for IMCA approval but can also be used on the street with any aftermarket brake system that specs these GM Metric calipers for their brake kit. Brand New Casting with Low Drag Piston Seal and Street Friendly Dust Seals When we designed our IMCA approved GM Metric disc brake caliper we realized the majority of the sales would come from racers, but we also wanted to ensure that this disc brake caliper could be used in road going applications, as this brake caliper is very popular in rear disc brake conversions and for custom installations using , either application specific or universal clamp-on or weld on options. To that end, we fitted the 2-3/8-inch diameter piston with a low drag piston seal that retracts the piston slightly, pulling the brake pads away from the rotor for better fuel economy. Furthermore, standard piston dust seals are included in our brake caliper casting for extremely low maintenance requirements. These disc brake pistons are designed to fit best with 1-inch wide disc brake rotors but will work with .810-inch rotors as well when fitted with our . When designing these new Metric calipers, we did change the fluid port to the much more common 7/16-20 thread. This opens up your brake hose and banjo bolt/fitting options immensely for custom applications. Our 16-inch is a great option that will work for most applications, but we offer several different in various lengths for your project needs. We do not include brake caliper slide bolts and highly recommend our (two per caliper) that does not use the factory slide bolt bushings in the caliper. These GM Metric calipers use readily available replacement or performance found under the FMSI D154 pad shape reference number.
