anyone out there with an 05 or 06 truck have rear brake issues. when my brakes warm up my rear calipers seem not to release completely, and i have a lovely brake squeel when i drive off. let the truck cool down and it goes away. it was just at the dealer yesterday and they say there is nothing wrong that they can see. This truck it turning into a nightmare. the only thing that seems to work right is the engine belive it or not(6.0L). any opinions???
