Chevrolet Other

I was driving my 1984 Chevy Blazer K-5 Silverado a few days ago and heard a loud pop and all of a sudden the car pulled hard right. I kept driving turning the wheel almost to 10 oclock to make it go straight, I smelled something burning and smoking while driving. There was lots of smoke comming from the right front fender well. When I hit the brakes to stop, the car pulled hard left. After a few lights the brake pedal was really soft and I could push it to the floor before the truck would stop. There was no pressure on the brakes. I didnt see any fluids leaking whatsoever. Does anyone know what might be wrong?
