You may have a bad wheel sensor or broken ABS sensor wire.
Go to Auto Zone or Parts source and they can scan the computer on your can for free.
If the computer detected any one of the sensor going bad or is bad, it may be in the memory and you'll know if it is the ABS sensor or the ABS module it self.
Good luck and hope this can save you some money. I had the same problem and it was my wheel bearing going bad which messed up my ABS sensor.

you will need to take the two bolts out of the strut that connects to the spindle backing plate.this will let the backing plate pull out enough to pull the cv axle out.

a quick test is to disconnect the sensor connector hook up and ohm meter to the sensor connector on the hub side not the engine side and spin the hub if the resistance rises and falls you're most likely ok if the resistance reads 0 or infinite you have found the bad sensor..this won't always be the case but it's a good start in the right direction

Its the abs sensor, if you encounter an ice patch or snow you won't even be able to stop because the pedal will will push back and make the rip grind noise. If you pull the ABS fuse out, you won't have ABS but you can stop and you won't have the grind noise and back pressure for now. Its safer to not have ABS when the sensor is faulty.
