Brake Squeal Helpno excuses

What kind of maintenance is necessary to reduce/eliminate the whining sound of the brakes after they have worn in for some time? Thanks in advance for any suggestions.

it could be a couple things. i could be dirty rims. you can clean them with a little soap and water, or stick a small piece of sandpaper between the brake pad and the rim, hold down the brakes hard and spin the rear wheel. be careful and make sure the sandpaper doesn't rub against the tire or you'll regret it.
also the pads could be out of alignment. you know when you take a piece of chalk and push it up on the chalkboard it squeaks? well brake pads are affected by the same phenamona. just check the yaw of the brake pads. usually though, caliper brakes don't have this problem nor do v-brakes.

NO - DONT use sandpaper, that will gouge the rim. Use fine steelwool or scotchbrite. Also, lightly 'file' the surface of the brake pads because they are glazed over with road crap. Toe the brake pads in 1mm. = no more squeal.
