the most likely suspect? Incorrect installation and adjustments.
There is nothing unique about the brake parts or setup on this vehicle, many vehicles have this similar form of rear disc brakes with older style brake shoes inside the rotors.
With the smoking you are seeing, something is definitely dragging to cause the friction and overheating. Could be the emergency brake shoes or the caliper not fully releasing when the brake pedal is released. It is easy enough to diagnose, place the vehicle on a lift, transmission in neutral, with the emergency brake handle fully released (down) and rotate the wheel by hand and see if it is dragging (hard to turn). If it is, remove wheel and slide disc brake caliper off rotor and see if rotor is still hard to turn, if it is, the emergency brake shoes are dragging and adjusted too tight. If removing the caliper releases the dragging, then the caliper is faulty.
One other possibility is the rear rubber brake hose has collapsed internally and not letting the calipers release the pressure when you let off the brake pedal. But this would affect
BOTH calipers, not just one of them unless you have a single faulty caliper which is not releasing which I have seen before in my many years of mechanicing.
This is a simple brake system and should not be too difficult to get it right, especially with all the new parts.
I suspect with the parking brake problem, the issue is the brake shoes, not the caliper....
