Front brakes
The front brakes on the GM Brazil GMT400 Silverado and Tahoe evidently were a dual-piston (54mm) caliper system, which used a caliper bracket / caliper assembly.
Upon casual observation, they don't look like a bolt-on replacement for our calipers.
Their dual-54mm calipers would have the same piston area as our 76mm/3" JB6 caliper.
The front brakes are illustrated in the attached document, snipped from the GM Brazil GMT400 factory service manual.
The calipers can be found used and reman in Brazil, e.g., here:
FWIW, the GM FSM doesn't show specs about the brakes, e.g., rotor diameter, thickness, drum diameter, etc. What specs I've found came from third-parties.
