I purchased my 900 last July, and all is well with the exception of my rear brakes, and rotor. I noticed today that my rear brake rotor is grooved and the rear brakes have been pretty squeaky. Is this covered under my one year warranty, or is this considered wear and tear. I took it in for my 600 service and told them that the brakes seemed to be rubbing, and they said they adjusted them and that all is fine. Any thoughts would be appreciated.
