Any air in the system in a Juin Tech would likely render the caliper unusable. It's a closed system so that would indicate a leak. It wouldn't be long till there was no braking at all.mikemelbrooks wrote: ↑Fri Oct 06, 2023 8:08 amIt could be that the actual disc is expanding. We run a massive 225mm ebike rotor on a tandem and it's not unusual for us to have some rubbing which goes away when everything is cooled down. Also any air in the oil reservoir will expand and if it's not vented properly can stop the brake pistons from retracting.

There can be no such thing as a totally sealed system, either there is some air that can expand and contract to allow for wear, or some kind of diaphragm as in Shimano brake levers.Mr.Gib wrote: ↑Fri Oct 06, 2023 4:29 pmAny air in the system in a Juin Tech would likely render the caliper unusable.
