Occasionally my antilock brakes engage when I am stopping on dry roads. The pedal briefly pulsates as the car is coming to a complete stop. The pads and rotors all new, and the car is not pulling.

I am guessing that maybe one of the sensors is going bad. Any ideas?

 

Could be one or 2 tires found a slick spot on the road.

 

The sensors are integral to the hubs, have you changed hubs lately?
when the brakes where changed were the ABS connections disconnected and reconnected?
