Squeaing new Shimano disc brakes
I am new to this forum and pretty new to biking. I mean, I was biking when I was I child and decided to switch to bike for commuting at the age of 39.
I bought myself a city bike, with aluminum body and hydraulic disk brakes. You can see the bike here: http://tinyurl.com/kk59fx
It has Shimano hydraulic disk brakes (Shimano Deore M485 Centerlock)
I have two issues with these brakes:
1 - front brake is much stronger than the rear one. I do not mean more efficient from a dynamical point of view, but simply brakes the wheel stronger than the rear one. Is it normal? I went back to shop which sold me the bike, but they say it is normal and that rear brake will get stronger with time. I don't know if I can believe that. Any advice?
2 - rear brake, in addition to braking less efficiently than the front one, also squeals. The squeal is absent while braking at high speeds, but appears at lower speeds and gets louder and louder just before stopping. Now, that is really annoying. I feel like a fool. I payed 1600$ for a bike and at every traffic light grab attention with my squealing. It is almost a brand new bike. It has 60 km on it. Is it normal? Is it possible to fix it.
OK, these are my questions. I will highly appreciate any advice. At the age of 39 I can not chase the teenagers around the house for an advice, and I don't have much confidence in shop personnel. Thanks God for internet and forums.
