calipers have very little to do with squeaking/squealing... the pads and discs do.
what brand, and TYPE(resin/organic?, semi metallic? Metallic?) of pads are you installing/replacing?
same info on the disc used, please.(Brand? Center lock? 6 bolt?)
also.. once contaminated, the pads MUST be replaced... no amount of chemicals will get the oil, etc. out of them.
yes, i've tried.
the most effective treatments were resurfacing the discs with 120 EMERY Paper (NOT Carpenter sandpaper), and refinishing the pads on the side of my grinding wheel, after soaking in electrical contact cleaner, then sun drying.. they still went back to squealing a day or two later.... sigh.
something i have not tried yet, on bicycle brakes..."disc quiet" pad coating... you apply it to the back of the pads... it's similar to silicone gasket stuff, RTV, but really high temp... available at any auto parts outlet.
