I purchased '93 Accord wagon, the left rear caliper was stuck and made the wheel very hot. I replace the caliper and pads, it makes a rubbing noise, most noticeable when backing up. Also the ABS light comes on soon after you get going. Is the rotor warped?

 

If the wheel got hot there is a good chance the rotor warped.
You can roll along slowly, and lightly pull on the parking brake [or lightly step on brakes] to see if it gives a "on/off" feeling.
As far as the rubbing or scraping noise....maybe the brake pad squealer tab is dragging ?
It would be best to jack up that wheel and spin it backwards to find the noise.

 

Wow...there is someone I haven't seen in a while......"hondadude", I hope things are going ok.

Sorry to the OP, just haven't seen/heard from hondadude in a while.
