Re: light brake pedal pulse
This may sound crazy at first read but I have experienced it first hand. A wheel bearing starting to go out will start to shed very fine metal "dust". That metal will work its way into the wheel sensor area and cause false readings. Obviously that may not be your problem but it is a place to checkout. You won't be able to simply pull the sensor and wipe off and say your done. Pull the wheel and inspect the wheel bearing with your eyes and feel it by spinning with your fingers.
