Eclipse - Mitsubishi :: Smell Of Burning Brake Pads

Ok, so my brake pads are actually not smelling like "victory" right now. what these symptoms might mean?

Background: 1996 Mitsubishi Eclipse. I think this might have all started when I hit the brakes pretty hard one day, hard enough to normally skid a car but the car has ABS, so it did not skid. Didn't notice these signs immediately after, but they have happening for weeks now and here they are:

Front driver's side tire bumps, sounds like a jack hammer but slower. Can get bad enough where I feel the steering wheel jarring so I have to hold on with both hands (I don't have power steering.) At first I suspected bad tire maybe, but the tire is fine.

First few times it did that, it smelled like burned brake pads. Only saw this once at night but the rotor got so hot that when I pulled over to look, it was glowing orange. It do longer smells like brake pads, but it still shakes.

The shaking and hammering stops and starts form one day to the next. I drive on the highway, then maybe 20 minutes I have to pull over and drive on the road. If I let it rest an hour, it might go away.

It happens randomly at different speeds. One day it does it at highway speeds, the next day, 40 and some other day at 20mph. I jacked up the car and got both front tires off the ground. Then I started the car and put it drive:

a.) the left side would not rotate!
b.) gave it gas, the tranny shifted gears, got up all the way to 35 "mph" on the speedometer, and still the left tire would not rotate.

The tire can rotate with enough applied force using a crow bar. Nothing terribly strong...18" bar, I would say 20lbs torque. By the way the 30 amp? ABS fuse in the hood is not there, never has been. I lowered the car and it drove. But it still acts up from time to time.

edit: it doesn't shake so much now as it does hammer. But I really don't feel the car tire hammering or bumping, I can hear it. Metal to metal, like a little gremlin is hammering the inside of the hood or something.
