@ascentale@sfba.social @rasterweb@mastodon.social @bikenite@fedigroups.social #BikeNite A3. Squeaky disc brakes are generally caused by mechanical vibration of the pads or other components of the brake system, and sanding the rotors is unlikely to help, although sanding the pads might, *if* the pads are glazed. Caution: brake dust is toxic.
Some brake pad compounds are more prone to noise than others, and constant, tentative use, or prolonged light use can tend to glaze the pads.

@ascentale@sfba.social @rasterweb@mastodon.social @bikenite@fedigroups.social First, make sure all parts are clean, undamaged, properly installed, aligned, torqued to specs, and adjusted for proper clearance. Then, if necessary, bed the brakes in with several short hard stops in succession. This isn't always necessary, but it can improve brake system performance. Usually, simply riding and braking normally is sufficient, with the understanding that initial braking performance may be reduced until they bed in well. (cont)
