I am a new cyclist in Bonn, Germany. Someone gave me a free bike that is very nice, but the rear brakes squeal like crazy, and the weird thing is that when it rains and they are wet, they don't squeal at all, which is the opposite of what I have read, since often people's brakes only squeal when they are wet. What could this mean? Any ideas of how to solve this problem, other than pouring water on my brakes on purpose? Lol! The brakes are new and they work fine, just to give you more information. Also adding that they are rim brakes.
I know a lot of people don't care about squealing brakes, but I mean we're talking, if rode my bike past 11 pm I could wake up entire apartment buildings! And I seem to be the only person in Bonn with this problem, so I'm not going to lie, it's embarrassing. I definitely get looks too! I could just get a new bike but I guess I'm wondering if there is possibly a simple solution. I already asked a bike repair shop and they didn't think anything could be done, but that was also before I had this piece of information that they don't squeal when wet.
They are rim brakes.
