so i decided to try to change my rear brakes by myself last monday. i have done a few different vehicles with some friends and thought i would be fine. that was my first mistake. i was only able to get one of the calipers off of the rotor, and when i attempted to push the piston back in to get the brake pads installed, i could not get it to budge. I had a 6" clamp that i bought at autozone in order to do this task. it would not turn. I actually bent the arm that you turn to tighten the clamp. I figured something was wrong. So, I decided to put the caliper back on without the brake pads, and have it towed to the local shop. I called the tow truck, and the guy said he had to move my car. I warned him that there were no brake pads on the vehicle in the rear. I was very hesitant, and asked if it would be ok and he said, "it should be fine". so he backed up my car, and put it on the truck. a few hours later, i got a call from the shop stating that i was going to have to buy 2 new calipers because apparently, when the guy hit the brakes, it blew the piston off of the caliper. thus, he said he could get them at cheapest, $220 a piece. with labor and all...$660 oh, and i forgot to mention, i payed the guy $60 to tow my car so that i could get raped. thanks a lot dickhead.
