Pardon my ignorance, but if it is listed somewhere else, please by all means send me in the right direction.The previous owner of the bike had apparently not taken very good care of the bike. When I took ownership, the first thing I noticed was that the rear master cylinder had a bunch of tiny micro stress cracks on/in it. It was barely holding on to the frame as it was anyway. I went to the local Yammy place and picked up a new master cylinder. I have it on the bike. Now, here is where I have no clue what to do next. I know that I need some DOT 4 brake fluid, but I can't simply just open up the top, and pour it in there. I am thinking that a brake bleed is necessary as there might be air in the lines. Suggestions, tips, websites, diagrams??? Any and all help would be greatly appreciated.
