I'm by no means a brake expert, but I am a machinist, specifically grinding. When a workpiece starts squealing, it's time to dress the grinding wheel because it's 'loaded up'. Could this same phenomenon be happening to the pads?
You'll have to be more specific for the non-machinists (like me). What's involved in dressing the grinding wheel?
Doh! Sorry for not 'splainin' myself.
Dressing a grinding wheel is a method of running a diamond across the surface, typically following a cam to keep it true. The diamond cuts a small amount off of the face of the wheel, giving it a fresh surface.
Take the brake pads out and lay a sheet of emery on a flat surface, like plate glass*, and slide the pad over it a few times with light pressure. Scuff 'em just enough to remove the glossy shine and make the surface fuzzy again. Be sure to spray them off with brake parts cleaner before reinstalling them. Braking should improve, too.
* Not a galss plate, mind you. SWMBO would be pissed, not to mention a glass plate isn't very flat.
