Usually caused by lack of backing gaskets and little lubrication of guides and guidepins. Usually lubricant like CoppaEase or similar applied to backs of pads and guides/guidepins.
All the best, Peter.
700/900/90 Register Keeper, Volvo Owners Club (UK).It's not even a couple of months old after I serviced and replaced front brakes (rotors/pads) and began to squeal. Checked it and didn't notice any unusual problems besides guide pins are a little tight so I loosen 'em a bit. Any idea what these may caused. Thanks for help.

how can your guide pins be too tight ?I used grind a lead in edge on my drum brakes and on some pads years ago but we have three volvos and they never squeal .You can try putting a chamfer on them or a thin sliver of copper between the pad and the piston cut to the shape the pad so it absorbs the harmonic vibrations or squeal maybe they need a good deglaze with a little carborundum fine grit .
