Hello, my name is Bobby. Were they really hot and dragging or was the smoking primarily what you were concerned with?

They were not releasing....the caliper with pads went on rotor loose but i assume when i pumped breaks for test drive they locked up....we took caliper back off and mashed breaks and caliper closed more but wont go in

If you cannot compress the piston in the caliper then you need to open the bleeder and see if it will compress. If it does not then the calipers are bad. If it does then make sure that you did not kink the hoses. If you did not then you may have a master cylinder issue. It is common for the master to fail if you compressed the pistons and debris went into the master cylinder. One other thing that can happen would be that the brake pads are too thick. This happens on a lot of aftermarket pads, especially if they came from Autozone.

If the caliper was loose and then stayed applied after you pressed on the brake then you need to narrow down what is going on. Make sure there are no kinks in the lines. Then to isolate it you need to pump up the brakes and see if the rears stay applied. If they do go and crack open and close both master cylinders lines really fast. You do not want to let air in. If that releases the rear brakes then you need a master cylinder. If not then you have a restriction someplace in the rear lines. Hopefully it is not in the ABS module.
