First let me say this could very simply be just new owner paranoia kicking in so bear with me. At this point I have a whole 800 miles on a new 2011. Long story short I am taking it in a few days to do the 600 miles service. I noticed today that the rear caliper is significantly hotter than the fronts can still touch but barely. What led me to this was a faint noise coming from the rear end that isn't the brakes dragging or anything similar to that, more of a hollow constant most noticeable in the 35-40 range like something is potentially dragging but i know its not the pads. It isn't strong just something i noticed.
So now I am paranoid about everything. I did let it cool and tried a few varying rides to see the effect include limited or not use of foot brake. Long story short rear caliper seems to heat up the most if i maintain a constant at the 35-40 range for a few minutes and gets right up there, the Rear pumpkin is leaching heat from the caliper but is significantly cooler, and the discs themselves seem to be at relatively the same temp both front and rear just comparing by touch (I know not the most accurate but you get the idea).
anything specific I should look out for and have the dealer check, beyond saying hey it makes funny noises. Hell new to RT land maybe this is just the way the final drive sounds for all I know. Any feedback would welcome and appreciated.
