Rim brakes are howling , what do I do? Have rim brakes on my two month old road bike , and they are starting to howl when used. Cleaned the tires and rims but that didn't solve the problem
the problem usually is that the contact between the pads and the rim is too parallel; a secret is too give the pads a tiny angle, so that the front part of the part would touch half a MM before the rear part.

Try it, it will work. I understand it might sound strange to understand, so if you have any question just ask.
