Tire Fire

I drive a 1992 lincoln towncar I just recently had the drivers side head gasket replaced and a new cam put in. Well when I was driving it home the ABS light came on and wouldnt go off the next day while I was driving down the road smoke started to come from the drives side hood area. I got out of the car and looked to see what it was. My drivers side tire was on fire. A guy came out of a nearby store and extinguised it for me. Well when we treid to push the car out of the street in neutral the car wouldnt move the brakes were locked. The car starts and runs fine now the brakes dont work they just go all the way to the floor. I checked my brake fluid level and it is full, anyone know what may of happened and is it fixable?
