This may seem an oddball answer to your brake pedal pulsing problem, but if
you have a torque wrench try taking off your front tires then installing
them by tightening them in a criss-cross pattern to 1/3 the total torque,
then 2/3 in the same pattern, then up to full torque. A guy with an air
wrench who cranks one lug nut to full torque (or past it), then another,
etc., will warp the rotor . . . .
