Master Cylinder, to rebuild or buy new
« on: April 21, 2015, 05:21:48 PM »
Hey guys, so I've been thinking of either rebuilding or buying a new master cylinder, to go along with rebuilding my caliper for my '77 CB550F.

If I were to buy a new master and clutch lever set, it'd have to be with threaded mirror mounts, and work with the stock cable and brake line (or stainless line, why not upgrade?)

From what I've seen on eBay, I have a few options. The $20 ones seem a little sketchy to be putting my life into.

I'll have to email them to see what the bore is, I've heard the recommended is 12-14mm for our bikes.

If you recommend anything else, please post it!

Id go with this for the same price. Period correct, if that matters. http://www.davidsilverspares.com/CB550K-1976-USA/part_123902/

Mine won't have the mirror mounts like you're looking for but I brought some used Honda CBR levers and this is how they look on mine. Probably a lot safer than the Chinese ones from eBay that you posted & costed me the same & compatible with the steel braided lines that I have installed on my 76 CB550.

My stock one is in great shape, other than the brake being almost useless. So I thought instead of rebuilding it, I'd get a new set with clutch as the levers hurt my hands. My dad has a set of levers on his CB750 that have a bend and indents like the newer bikes do, and they're very comfortable.
