Ok now this isn't my first brake change by a long shot but I need a little help from anyone who knows these new Gen III trucks.
Well I replaced the rotors all around, the parking brake shoes and springs and pad's. All wheels work great except the left rear wheel is griding. Now I isolated that it's not the parking brakes. I test drove it and it was great for about 1 mile, then it started grinding. Now when I say grinding it's I mean grinding, I can rotate the wheel but there is plenty of resistance. I suspected a bad caliper, so I tested it and it seemed fine but I figured I would replace it just to double check and no help. The pads are Raybestos as are the rotors. If it was both rear brakes doing this I would thik that it might be the return port cloged on the MC but with onle 1 rear hanging I doubt it. Also before anyone mentions lubing everything up I already did that.
Now back to the test drive, like I said I drove it for a mile before it made this noise, I drove it back home slowly and heated things up pretty well. On my hand help radio shack temperature meter it got to just about 300 degrees, not hot enough to warp the rotor, (I check that with a dial indicator) but the pad might be somewhat glazed.
Now before I go and dress the pads, pulling rotors to double check mesurements (unlikely to be bad tolorances) and swapping rotors to see if the problem follows the rotors what ideas do any of you have. Any ideas would be appreciated.
