I recently bought a new bike with disc brakes. In fact, I bought it just for the disc brakes. I wanted to avoid having to buy rims every 12-18 months, and I also got tired of squealing rim brakes in this wet climate. (And I wanted a new bike just because I was feeling self-indulgent.) I'm pretty happy with the disc brakes overall: they require much less cleaning/maintenance, and they have great stopping power even when soaking wet. However, they still make noise. They make faint scraping sounds when totally dry, and they do make a squeaking noise when wet or when I'm riding at low speeds. It's an improvement over rim brakes, but they're not the totally silent brakes I was hoping for when I bought this fairly expensive bike. Is this normal for disc brakes? Is there something wrong with them? Am I being unrealistic?
