I got a leak in the metal line coming off of the master cylinder. I have a parts manual I believe the part is number is 40971-00. But the manual is a little unclear. There is a rubber hose that goes to the caliper, then the metal line that goes leaves the master cylinder then back to the rubber hose. I need the metal line. I am thinking that 40971-00 is the whole assembly. (diagram points to the rubber hose) Anyone replaced this?
