Will try this. Any other ways of telling it's the FCABs?

This is why you should really replace both sides when you replace either pads, discs or calipers. Other possibilities? Air in left caliper pipe? Contaminated pads on left affecting traction? Uneven pad thickness on either side? You should bleed the system again for sure. Both sides not just the passenger side. Open both bleed screws at the same time. But sounds to me like you need to take a look at the efficiency of the remaining caliper with view to replacing that one as well.
Do calipers/brakes normally become less efficient/effective over time? I guess a rebuilt one is different than one that doesn't show any problems?
