Yes. It could be a sign that the mechanism inside the calliper has failed. I know of one occasion when despite fitting a 'new' exchange calliper, it also had this fault. Maybe try removing the calliper, get someone to operate the handbrake and see if the piston moves?

I thought as much, ive just taken the wheel off and got my boy to lift the hand brake while I was watching the caliper, the arm moved as the cable pulled on it but the piston didnt:(

I fitted a pair of 'new' rear calipers to my Uno a couple weeks ago and one didn't work on the handbrake...fixed it though by undoing the bolt that the return spring coils around, rotating the plate the cable hooks onto beyond its normal stop position beyond a 'click' point, applying the footbrake as hard as possible then returning the plate back to its normal position and putting the bolt/spring back on :-)
