I have 21K miles on my truck right now. Since it was brand new the rear drum brakes have squeaked when cold driving and just before coming to a full stop. I took it to the dealer and they said that the pads are perfect and it's just the nature of the beast. I've lived with that until now.
A couple of days ago I rotated the tires. I had jack stands under both sides of the rear axle and put the parking brake on. With the parking brake on hard the drivers side wheel was rock solid and didn't move. On the passengers side the wheel has about a 1/2 inch turn play. The other side stays perfect still. You can rotate the wheel 1/2 inch or so both ways before it hits something and stops. It acts like the pads are tight but move between the mounting post or caliper. Maybe the caliper is loose inside.
I am going to stop and get a couple of bolts to free up the stuck drums tonight and check it out. Has anyone had this problem?
What really chaps my hide is that the dealer said the brake pads were OK. No way have those drums ever come off. They are frozen solid. They never looked unless they have some special ultrasonic or x-ray, device that can "see" inside the drum without removing it.
