The other day I backed my 00 vette out of the garage to let run for a while. I let my car idle for about 20 minutes , I then went to put it back in the garage. When I pushed down on the brake pedal , it was so hard , i put the car in gear and noticed the front right caliber was locked up. I shut the car off and left it alone for about an hour. I restarted it and everything was back to normal and I was able to pull the car back into the garage with no problem. :WTF could it be abs or what.
