You may have to explain. I need to undo the hose to extract it from the frame, can I seal it somehow to do so?
Nah, just carefully unattach it, removed from frame, and then reattach it to the levers.
You might be lucky and not need bleeding, but if it does, just a simple case of injecting more mineral oil in the system rather than a complete rebleed.
