Mark, I was trying to see how you can apply stick-on pads to the rotating part of your motor, until I realized that you were talking about the brake rotors which had the brake pads oscillating and squealing. Apparently that is a known problem, as almost every brand of car has some solution to keep their brakes quiet, either a plate that goes on the pads or some other solution to avoid resonance.

The anti squeal shims fixed the rotor squealing problem. They're part number 9500-4 by SBS (Scandinavian Brake Systems) stock #1702-0033. You cut to size & peal,stick them on the back of the pads. I also chamfered 1/8" 45 degree on the 4 sides of the pads per Samba recommendations and with an abrasive pad put swirls on the rotor both sides. I used high-temp grease on the pads edges (did all this stuff before too but still squealed like a stuck pig). So I think the stick on pads did it. The Impulse 9" is showing noi wear on the brushes/comm after fixing the brush rigging (& timing set to neutral).
