Question

I have a 96 Subaru Legacy Outback 4 W/D. I am having brake problems that I cannot resolve. I just did a complete brake job - turned all rotors, replaced pads with Raybestus Quiet Stop premiums, and replaced the front wheel bearings. Now when I apply the brakes as the vehicle slows down the brakes make noise, the brake pedal shudders/pulses down almost as though the ABS system is kicking in on a skid. The sound is a rubbing noise to the motion of the wheels, then after stopping and resuming in motion there is a much lighter rubbing sound for a short time period. Sometimes if I pump the brakes when this happens the problem will stop but resume when the brakes are applied next. Several times the ABS light has lit on the dash and when this happens the brake system operates normally and perfectly without any noise or pulsing/shuddering.
I have removed the pads and returned the rotors a second time as well as roughed up the pads and reinstalled and still have the same problem. The noise seems to coming only from the front end brakes, not the rears.
Does anyone know what is possibly wrong or what I need to do to correct it??? Please advise?? thanks
