I have a 1999 Dodge Carvan that was wrecked in the front. My insurance totaled it. I bought it and drove it 12 miles home with no problem. I then drove it 7 miles to a body shop to get the radiator, bumper, grill, and headlights repaired. After the hood and fans were replaced the shop called to have me drive the van home. I made it about a block before I traced the transmission fluid back to the shop. They put some more into the transmission and it does shift fine. However, the brake pedal is hard as a rock and the brakes are engaged to the point that it will cause the pads to smoke. I tried to release the calipers and one is stuck. What would cause the brake fluid not to release the pads? Of course the body shop says it isn't their fault. I don't understand why the van drove fine before the shop and after the body work it is having brake problem. Thanks for any help or advice.
