As for the hose issue, if you seem to have one or more hot rotors and others that seem cooler I would change the hoses just because it's the most likely problem at that age. What happens is they collapse internally and don't let the pressure off after an application so they tend to drag the pads, which makes for a hot rotor. Extra heat makes the rotors warp and gives you that vibration.
If I open the bleeder and the rotor spins freely am I to assume it is the hose and not the new rotor? Can I crimp the flex hose instead of opening the bleeder? I've seen this done and am unsure if that is ok to do?
