I have rear brakes that squeal, and I'm stumped. 1998 Acura SLX. Generally excellent condition and well-maintained. This fall I noticed the rear brakes squealing on stopping. I checked the pads a few thousand before and they had plenty of friction material. I ordered some Raybestos Premium Ceramic pads "Quiet Stop". I installed them and I found one set of pads wearing unevenly fore-aft, and a very stuck caliper bolt. Rotors look fine. Calipers seemed fine. The Raybestos pad had a metal backing plate on them that precluded fitting the stamped steel shims back along with them, so I just added a generous amount of Disc Brake Quiet (the orange goo) to the piston and the pad, let it set up, and re-assembled. I cleaned and lubed the caliper pins and used anti-seize. Wheels spun ok after assembly w/o dragging/sticking. Braking performance is great; one of the pad sets was clearly sticking and dragging, also robbing some mpg I think. Drag is gone. I followed a standard break-in/bed-in procedure with the pads per instructions (rolling slow downs multiple times before full stops). I still get a squeal on stopping, though much less than before. I jacked up the rear and spun the wheels - no drag on either side (front either for that matter). I flushed and bled the brakes, too - performance gain but no change in squeal. Squeal maybe worse after bleeding. I'm baffled as to why. Should I: a) open them back up and try to get the shims in now that the pads have worn a bit? b) something else...? 2nd question - I noticed on the back of the pads, while all were identical, two of them had a clip riveted in one corner, sort of to pull them with? Not all four did, only two. Are those supposed to be inboard, outboard, or...? Like the little clips on the two of the four pads in this picture: http://www.autotrucktoys.com/ram/Mopar-Dodge-Ram-OE-Replacement-Brake-Pads-PRD35698.aspx Haven't encountered that before on a vehicle. Are they supposed to go in a certain position? The instructions from Raybestos did not illustrate them or mention them; I checked.
