I just got this car with not much history,rt front caliper stays applied until i open bleeder screw and push back the padsusing a little pressure but not much,pads will not retract without opening bleeder even using a large c clamp,seems like a check valve is inline and stuck,or poss the rubber line colapst inside,but Ive never come across a colapst line .also no hot heat just warm and ac works.Ive been a machanic for many years never worked on many caddys and mostly harlys davidsons the last 20 years, any ideas would be helpfull ,also caliper pins are like new car has always been garaged everything looks good, thanks for ideas.

    needs brake hose. make sure you flush the system when you are done.
    heater core could be clogged. take the temp of the inlet and outlet and look for a 30-40 degree change.
