Have the ABS scanned. It is most likely a wheel speed sensor/circuit problem but a scanner is needed for testing!

Do you hear ABS activation at times when stopping and turning the steering wheel? Sounds like a growling noise and the brake pedal kicks back a little. IF turning when this happens, most likely a connector problem. If it does this at any time most likely a sensor problem. Scanner will conform which wheel the problem is at.

I think it does kick back the pedal a little. Ill drive and test it and you said it might be a wheel speed sensor or connector. What kind of connector are you referring to?

Wire connector or plug.
