My Bombardier SV200 SkiDozer has a disk brake for the emergency brake. It doesn't seem to be original (the mounting for it at least). I smelled hot brake lining material the other day and the brake was very hot. I took it apart today and see the pads are fried. Does anyone in the forum know what might have caused this? Would air in the brake line keep enough pressure on the cylinder operating the pads that they'd overheat?
