Had a mechanic replace my rear pads. After 1 week or so...I noticed a brake smell after driving it. I touched both rims and they were both warm/semi hot. After another week...it went away. This lasted 2 weeks and the brakes started grabbing again...When I was driving one day...I tried to pull the ebrake up and down real hard to see if it would help release the grab but it made it worst...the brakes were really grabbing/locking now and then I had to pull over. The brakes were locked up and the car would not move. I sat there for an hour to let it cool and tried to go again and it released to the normal grab and I got it home. Can someone tell me what to check for? Could it be the E brake need adjusting? Its a 87 starion ESI.
