After disassembly of one set, there appears to be a slight bend on the forward arm. The washer between them is really thin. I am debating weather to try to provide clearance by bending or thicker washer or live with it.
The other surprise is the strength of the springs. I used a bench vice to compress the spring for disassembly.
the backside arm is bent forward, probably from a whack of the upper extension against the downtube, I have corrected this before way way back reasonably often.
‘the arms should rotate without interference. This IS Campagnolo. Take the caliper apart, copper jaws in the bench vise, hold the arm by the pivot washer region and show it who is boss.
‘the springs ARE stiff. They can be ‘detensioned”
