Some discussion here:
The rear rotor/pad stuff is similar to the front.
1.Raise and support the vehicle.
2.Disconnect the rear RH and LH parking brake cables (2, 5) from the parking brake equalizer .
3.Remove the rear wheels.
4.Remove the rotor .
5.Remove the shoe to shoe return springs (2, 5).
6.Remove the adjuster (3).
7.Remove the shoe hold-down clips (1) and pins.
8.Spread the shoes and remove the parking brake cable from the actuator lever (6), and remove the shoes.
9.Remove and transfer the parking brake actuator (6), and the spring behind the shoes (4) near the parking brake actuator (6) to the new shoes.
Parking brake adjust:
1.Be sure the parking brake lever is fully released.
2.Remove the plug (1) from each access hole in the brake support plates.
3.Insert an adjusting tool through the support plate access hole and engage the tool in the teeth of the adjusting screw star wheel.
4.Rotate the adjuster screw star wheel (move tool handle upward) until slight drag can be felt when the star wheel is rotated.
5.Back off the adjuster screw star wheel until brake drag is eliminated.
6.Repeat adjustment at the opposite wheel. Be sure adjustment is equal at both wheels.
7.Install the support plate access hole plugs (1).
9.Remove the supports and lower the vehicle.
10.Depress the park brake lever and make sure the park brakes hold the vehicle stationary.
11.Release the park brake lever.
I would think that if the parking shoes are holding up the hub removal you should be able to back off the adjustment start wheel. I haven't done this so I dunno how hard it is. My WJ was a real PITA, but it had a different lever and the cable disconnect was under a plate under the rear carpet....
