I'm hoping that I can get a little guidance about some brake issues that I've been dealing with for the last couple of months. I haven't done much brake work and have been trying to rely on a couple of local shops who have finally told me to stop bringing my Jeep in and suggested that I go to a Jeep dealer. I've spent a lot of time looking at other's posts and can't seem to find an answer specific to my problem. Here's the story:
Last year I bought a 99 Wrangler Sahara. About 5 months ago I brought it in to a local shop because one of the rears were leaking fluid. They put in new brake kits on both sides and cyllinders. Ever since then I've had issues with the right rear locking up. It is fine when I first start driving but after a few miles the right rear wheel will start getting really hot and locking up even with light pressure on the brake pedal. They tried adjusting it, then putting in a new proportioning valve and then finally changing out the whole brake job with new components. Nothing fixed the problem. I took the Jeep to a local Firestone for a free brake inspection. They talked me into putting in new cyllinders, another proportioning valve and new drums (they said the old ones could possibly have been contaminated). They also (supposedly) checked the brake lines and said that fluid is flowing to and from the master cyllinder without restriction. Firestone also put on new shoes which failed to fix the problem.
I pulled off the drums the other day and took some pictures. The right rear had a lot of drag on it so I backed off the adjustment and cleaned off everything with brake cleaner (it was totally caked with brake dust). The brakes worked better than they have in five months, for about 50 miles, then they started grabbing and heating up again (only the right rear, as usual). I backed off the adjustment again and everything was okay for a while, but now they're back to grabbing, squealing and heating up again.
I'm getting ready to leave for Afghanistan in January and really want to get this fixed so my wife has a decent vehicle to drive while I'm gone. Any guidance you guys could give would be really appreciated. I'm putting some pictures up so maybe you could see something that's blatantly wrong.
