Chosen Solution
I have replaced calipers and hoses on both rear sides several times, I’ve replaced the ABS box but the caliper on the rear drivers side is still sticking and is getting over 100° hotter than the other brakes from just a nine mile trip with a few stops but mostly its continuous driving between 45-60 MPH. I have a small child that I have to drive out of state for medical reasons and can no longer get rides from others so I need to get this fixed. Obviously it has front and rear disc brakes. Its four wheel drive with a 4.0 engine. Any help?
If you have problems only with the rear it could be a bad proportioning valve that is only working one way. If you have no joy here then check for pinched or crushed brake lines . It could also be a bad master cylinder that will not allow revers flow of brake fluid .However this would cause both rear brakes to size at the same time. It will also be a good idea to change the brake fluid if you’ve heated the brakes beyond there normal operating temp . Once its overheated it can begin caramelizing . My thought on this though is that you have a bad proportioning valve. Hope this helps
