My '97 K2500 7.4L (8600 GVW) has JD7 brakes.
I'll have those rear brakes apart as soon as I get the intake gaskets installed on the K1500. Again.
In '97, at least, there's JB8 single-rear-wheel, and JB8 dual-rear-wheel. The difference is in the front rotors--same diameter, but about 1/4" thicker on the DRW. That may mean that the calipers are also wider to accommodate the thicker rotors.
Didn't the dually calipers have a bigger piston anyway?
