Tried to drive to work the other day and the car wouldn't move basically, I drove for about 2feet and notice all 4 corner brake pads was forced against the rotors.

Seems like my caliper piston for all 4 corner isn't disengaging. I took off all 4 wheels and pushed it back in, re-pumped the brakes but the brake pedal which felt fine at the beginning..than it seems to tighten and won't loosen up (not sure how to explain?) The brake pedal barely has any play. I can't even turn the wheel freely by hand, front or rears with ebrake down. Can't figure out what's the problem. The caliper piston's doesn't seem to be seized.

Its probably the master cylinder is bad or the ABS pump. Needs more troubleshooting

I have seen this problem before, usually occurs when some one puts oil (not brake fluid) in the brake master cylinder. Every part with rubber would have to be replaced: master cylinder, abs unit, all brake lines, and all calipers. Take to shop and have brake fluid tested.

How would I go about in trouble shooting these?

I sure hope not. This sounds like a disaster...

Found out what the problem was. Seems when I replaced my brake light switch I didn't leave a gap between the switch when installing. Took it back off and left a little gap and it's back to normal again. Thank goodness I didn't go as far as replacing my mbc/abs module.
