Machine is a '11 T570. Occasionally, even if I haven't touched the brakes, they begin to drag, getting tighter and tighter until the engine really labors. Disc was starting to glow this evening when I stopped to look at it. I wonder if this is common, or if it's just a problem on this machine? (Not a lot of miles...4400 or so.)
this is not common and not normal at all.
