I have a 2005 Chevy Colorado I bought in 2008 with the 4 banger engine and 5-speed manual. Runs great but has had a problem since I got it. When it is below freezing, the right rear brake seems to lock up or get stuck when releasing the parking/e-brake. The left rear is fine. The trouble is when I try to get going in the snow or ice, that right rear tire won’t move until I give it enough gas and then it spins too fast and causes me to just spin in the ice/snow and go nowhere. The dealer said there was a technical bulletin and grinded off every other tooth on a gear that is supposed to adjust the brake when going in reverse. Or so I was told. That solved nothing. Every other shop I have asked about it says there is nothing wrong that they can see and the pads are fine. I just haven’t had them look when it is happening. Dumb of me, I know. The wheel got so hot once when I drove it this way I damn near burned my hand checking it out. I gave up on it for a long time, but now I am sick of it. What do you think?
