And clean the pads before reinstalling.

Place a rubber band around the rear portion of your brake pad; it will hang loosely with only one thickness between the pad and the rim. Adjust the pads to the rim, and tighten. This will give you about the right amount of toe-in. Wipe your rims with denatured alcohol, and clean your brake pads with sandpaper or a flat file. If that does not stop your squeal, it will at least help you to stop better.
