And the sliding mechanism isn’t protected by a rubber covering as most cars are, they’re open to the elements and if not used often enough they will seize up.

Is that not a dual piston? One piston either side of the disc.

No signs of a hydraulic line connecting across to the other side?

It'll travel through the body of the caliper - with a single pot, the caliper usually slides in a carrier, on dual pots the pads slide on pins.

My 1972 had dual pots with no connecting line.

Same with the uprated 4 pots, no line

It's not easy to photograph this... played with the brightness again.
I only see a piston on the inner side where the vent is placed.

If you take the pads out you will eliminate the guess work and know for sure, looks easy enough.

As I’ve said before, it’s a single piston.

Thanks for posting the pic Clemens.

Unfortunately the mechanism that allows the calliper to slide back and forth as the brakes are applied and released is not obvious from the angle you took the pic from.
