Just noticed the "hot" spots on my rear brake rotors the other day. They are visible all the way around the rotor in the same pattern. I bought the bike new last spring. Put 700 miles on it last year and took it to the dealer for the 600 mile check up/oil change and then garaged it for the winter. I've had it out a few times this spring (150 miles). The back brakes WORK fine. I'm wondering if anyone has seen or can explain the hot spots on the rotors. I can't be certain they were not there prior to the service, but I'm suspicious... Any ideas?
