Have a 2011 Suzuki Equator 4WD (AKA Nissan Frontier). Had to brake hard from ~45MPH a few weeks ago to miss some turkeys in the road. Felt like ABS engaged. Now, from time to time I get a random pulsing or slipping feeling in the brakes. Lasts less than half a second, but could happen multiple times if I'm braking for awhile (like slowing for a highway off ramp). All four rotors and pads were replaced (and brakes bled) a few months ago. It's not a warped rotor, as it doesn't happen all of the time.
