If you remove a brake hose from a hydraulic brake shifter (GRX 810) because the shifter is fucked and being sent away for warranty, do you need a new hose, olive, thingmy bob set up to put it back on or is it a plug n play on the old hose?
Depends a bit on how deformed the olive already is, I swapped a Deore brake lever once and didn't change the olive and it was no problem but if the olive is already very squashed it will be leaking.
