Front brake master cylinder rebuild kit

[Jabooneky]

I am having a hard time finding a kit for this. It’s off a 75 xs650b and has 14 stamped on it. Does anybody know where I could buy a rebuild kit?

Here's one on Ebay that they claim fits a 75.

I bought that exact part and it didn’t fit.‍

Yes and in my experience it is a false claim. I bought it and it didn’t fit

I feel like this is the factory cylinder but maybe not. The only other owner of the bike has been my uncle. I could call him and ask him if he remembers changing it.

Looks to be a Suzuki logo "S" in front of the "Made in Japan". Just an observation.

Not the mc I had on my 74 and 75.

The rebuild kits for early master cylinders do not come with the same piston that came from the factory. They are aluminum and are a bit shorter than the ones they came with. The replacement kits seem to work fine though. Prices range wildly on them though. I’d get one from Niche Cycle, they seem to have the most reasonable price that I’ve found.

Here is the thread I did on my 75 brake rebuild. it has pictures of the replacement kit from Niche Cycle Supply.
