The noise is an harmonic effect and does not diminish braking effectiveness. Still, it sucks.
Oil the brake shoe mounting hardware (curved spacers' edges and threads). Slack the brake shoe
holder nut, work the brake lever a few times until the shoe sits straight against the rim. Hold the
lever tight and fasten the brake shoe tight to the brake. Repeat for the other side and test ride
If still, clean the rim thoroughly and scuff any glaze off the pads. Hand cleaner or kitchen
cleanser with a fingernail brush and hot water over a sink is not too awful. Test ride for noise.
If still, repeat the brake shoe mounting but with a slip of cardboard (such as a flap from an
inner tube box) under the back edge of the shoe. VBrake shoes should theoretically be flush but,
since some arms have a lot of play, you may need to anticipate that with some "toe", making the
front hit first.
Some brakes just are noisy and cannot be made quiet but for most the above will be effective. If you
cannot quiet them, try another brand of brake.
