I dont know of anyone here who got anything out of freeing up the bobbins for pulsing myself included like Smiley said. Search"Front brake pulsing" on this site or elsewhere. The common fix is geting EBC double sintered brake pads which are metallic and don't leave a residue when hot at a stop. Careful with brake fluid, its acetone and eats paint really well. I prefer rubbing alcohol and some fine emory paper wrapped around a small block of wood.
