I suspect that it's the cable. There are two of them running from below the rear passanger foot-well and when I replaced mine recently, I noticed that the rubber grommets on either end had perished significantly. The cable takes about 15 mins to remove/replace each. The far-side one runs under the exhaust, and has a foil protector on it.
My personal take on it is that the moisture is working it's way into the far end of the cable. It's unlikely that the caliper mechanism is freezing because in operation it's likely to be hot, and will evaporate the moisture.
Here's a run-through of how to remove the cables:
Park in gear with hand-brake off.
Slacken the handbrake adjuster to the maximum and drop the handbrake fully.
Jack up car on either side, ensuring that good clearance is made to the far side of the car. Install two axle stands and a 'life-space' protector (a wheel to protect you if car slips/falls).
Disconnect the caliper end of the cable by moving the ball from the retainer.
Undo the clamp from the trailing arm (13mm bolt).
Cut the cable ties retaining the cable onto the trailing arm.
Unclip the cable from the heat-shroud around the exhaust.
Pull the cable sheath from the retaining clip at the handrake-union and loop it around until it's free of the exhaust.
To free it from the handbrake-union, pull cable to one side and then down. Connection can be stiff...
Repeat for far side...
Re-fitting is the opposite. Use new cable ties when re-affixing the cable to the trailing arm.
Cables are about €25 from Alfa.
