update:

Borrowed vernier caliper from a friend to measure B2 piston free play as per FSM. Free play was about 3.1 mm greater than spec. EPC shows 6 different length piston pins, shortest one is (was) currently installed. Installing 4th longest pin should bring free play back into spec.

I'm concluding from this that the B2 band is about "half" worn out. Not sure if my conclusion is correct but based on this and the K1 measurement, I plan to put it back together as previously described.

Stay tuned.....
