well sh!t, i've never heard of the JBx designation ... i've never heard of a 3-5/32 caliper for the half-ton bracket. how the hell have i gone this long reading THAT many articles on gm brakes, and never seen that before??
that's a 7.82 piston area
the JB7 mounts to the same bracket with the same pads as the JB6 ... just larger piston?
