Road an mountain levers use different flare nuts with a different thread one is M8, the other is M9.

Look at parts #1 in these 2 exploded diagrams.

Would the old hose be long enough?
Much appreciated for the detailed response. The old hose will definitely be long enough, might even be too long by a couple of inches.

This may be a stupid question but I am not familiar with disc brake hardware . . . Can I not just slide the olive and flare nut off the hose and slide the correct flare nut back on? Or is cutting it the only way? I do have extra hose length to cut if need be.
