Well a new wheel speed sensor didn't change anything at all. I even cleaned the socket the sensor slides into. I also was due for a front brake pad change, so I replaced the front pads and rotors, and made sure the two pad retaining pins were in place. No difference, I still have a very slight brake pedal pulsation only when turning right (like into a parking space) and only at speeds less than say, 5 m.p.h. What gives?
