Ok, so I am thinking that it is the left rear caliper dragging. I think a piston might be getting stuck, because the squeal starts after a few hard/high speed-to zero braking maneuvers. This tells me that the pads are stuck in contact with the rotor and are probably glazing up, and when i stop hard the glaze is being rubbed off and the pads are makin contact with the rotors. Also, the left rear rotor is more gouged and grooved than any other, which means that its contact is being 'more' severe--you can really feel the ridges, is this going to mean that I will need new rotors too?
Ok so now, what should I do to free the piston? Anything easy? Would it be easier to just take the whole truck into a brake place and have them install new rotors, pads, and make sure the calipers are working properly? I do not have the time nor the facilities to really take apart my own calipers, and if I was going to bring it to a shop anyway, should I just fork over the extra money for new rotors (if the scarring on the left rear is too bad) and a caliper rebuild? Any help would be nice, I am mechanically inclined, but there is only so much I can do in my apartment parking lot before I just give up the money and throw the truck at an 'expert' (at charging $$ that is)....
