Just came back from a trip to Colorado (from FL) and my brakes rumble when coming to a stop.
I step on the pedal about mid way and that's when they like to make the most noise and slight vibration (more of a rumble) in all four wheels.

Before I went on this trip my ABS light would come on sporadically, then shut itself off when I turned the car off. It would not come back immediately after turning the car on, only after driving for a bit, or it would not even come on.

I pulled the codes and cleared them one day from every module way before all this began happening trying to diagnose a check engine light that was consistently on. I cleared the ABS module (it had codes in it but I didn't write them down) and at this point the light had never come on before. It was only after I cleared the codes that the light began coming on. I also had the break system bled (in preparation for Colorado trip) before this all began happening.

I will pull the codes from the ABS at some point today and see what's going on.

My question is: are my rotors all warped all of a sudden, or is this an ABS issue? I'll look up and post my ABS error codes as soon as I acquire them.

Thanks everybody.
