I am having trouble with the disc brakes on my 6 week old Rocky Mountain Metropolis YVR bike. They are Tektro Novela 160. The brakes Screech and squeal extremely loudly. To give context to this; to say my brakes squeal is to say Canadians kind of like hockey or New Zealanders sort of like Rugby. The noise hurts my ears and animals run from it with terror in their eyes (ears?).
I have had it back to the bike store where I bought it and they have tried to deal with this 4 times. They have cleaned them , and adjusted them untill they say the brakes should be fine. They say the sound should go away after awhile. I say it never should have been there in the first place and I shouldn't need to run down hills with my brakes on to get this noise to stop. That didn't work anyway, I tried.
What can I do? Are there replacement shoes with softer compounds? Do I buy a boat anchor and stop using my brakes? What?
Here are photos of the brakes.
