I' m new to disc brakes and I just got a new bike with the 2004 XT hydraulic brakes. They feel great but I did notice that the rear brake when idle has the outside pad touching the rotor. The wheel still turns but not for as long as if it didn't touch.
When looking from above the caliper, the inside piston (closest from the spokes) is flush with the caliper body while the outside appears to come out just a bit (1mm max.).
Should I care? Or should I take off the pads, the reservoir cover and push the piston back in (if I try without taking off the reservoir cover, it just keeps coming back to it's same slightly out place). I'm kind of afraid to open that thing.
