GMA ENGINEERING BY BDL Rear Caliper - 87-99 ST - Classic Chrome GMA-202STC

If you're running classic H-D applications with undersized master cylinders, OEM rear calipers will leave you with inconsistent braking and safety compromises. The GMA Engineering rear caliper delivers the hydraulic pressure balance your bike demands, with a two-piston design engineered specifically for rigid frames and modern stopping power. Built in the U.S.A. with anodized finishes that resist corrosion, this is a direct upgrade path for riders serious about braking reliability.

This caliper requires a 5/8" bore master cylinder and pairs with 11.5" rotors—making fitment critical before purchase. Avoid older Wagner or Kelsey-Hayes cast aluminum units; they're incompatible with modern hydraulic demands and will compromise your stopping ability.
