GMA ENGINEERING BY BDL delivers a billet‑aluminum brake caliper that is anodized to provide a durable, high‑quality finish on the raw metal black‑contrast surfaces. The package includes hanger brackets and brake pads, and the calipers are manufactured in the United States.
These calipers are designed for use with a 5/8‑inch bore master cylinder and are not recommended for use with imported stainless‑steel rotors. They are incompatible with the old‑style Wagner and Kelsey‑Hayes rear applications, which feature a 3/4‑inch bore master cylinder and will not operate correctly with this caliper.
