1994 Jeep Laredo sticky or grabbing rear brakes

First thing to check are the shoes, is the smaller shoe towards the front on both side? There is a primary and secondary shoe on each side. Then check the wheel cylinders for leaking or frozen pistons, peek under the dust boots, I use a small pick, and just pull the rubber away from the piston. Then propper brake adjustment is done, then the parking brake is adjusted, some people adjust up the rears by tightening the parking brake, NO GOOD! Make sure the shoes rest on all stops and anchor points! If not loosen the parking brake adjustment until they do. This is a view of the right rear.
