I drove down the street and the brakes were dragging the entire time like i was smashing the pedal to the floor. When i got to the store brakes were smoking and when i tried to leave i couldnt move fwd or backward. They are locked on, so what can i do in a store parking lot w/ a slammed car to relieve the pressure on the pistons? Its a 93 teg w/ No ABS. Is the problem more serious like the master cyln. or booster failure? Need to go to work tomorrow please help quick as u can.

 

Probably either a stuck caliper or wheel cylinder. That is if it is just one brake. You may be able to get the wheel off and get it unstuck, if that is the cause.

 

tow it, flat bed. before you ruin somehting else
