Has anyone ever seen a pneumatic brake on a bike before?
Someone brought it into the shop because it wasn't working, both brakes seemed to be operated by one lever (with safety lever).
Are there things rare?
Also, they are rim brakes.

I've seen them once, on an old NIB Murray or something of the like. Huge actuator cylinder on the lever and little servo canisters betweeh the arms of the calipers... And a spagetti pile of tubing.

Never worked on them. If they aren't sealed units, servicing should be pretty straight forward.

Yep, that's it!
We just tool them off and put a cable actuated one on it.
