Did you get the figures of the brake test for the service (footbrake) ?

Was that side weaker too I wonder. Does the cable appear to pull correctly at the caliper if you watch it as someone applies it?

Would take a guess that its the claiper causing the problem. Had to do a few of these. Local factors keep them on the shelf; always a good sign its a popular part !

Remove the cables from both calipers ... make sure the levers move freely ... if not try release oil and work them til they are free ... if any lever is difficult to free that caliper will have to be replaced ... make sure the levers are back on their stops then press the brake pedal a few times ... you should be able to work levers by hand to feel brake going on whilst turning the disk by hand with not too much travel on lever ...

Then and only then replace handbrake cables and adjust handbrake lever ...
