Norton Master Cylinder Repair Kit
Rebuild kit of internal seals and parts for a front disc brake master cylinder.
SSB912 is a master cylinder repair kit, the internal parts that rebuild a disc brake master cylinder rather than a whole new unit. It shows up in the parts-book grouping for the handlebars and disc brake master cylinder and hose assembly, which puts it up at the bars where the front brake lever pushes fluid down to the caliper.

This is a rebuild kit, not a complete master cylinder, so it's meant for putting new life into a body you already have rather than replacing the whole assembly. Our catalog record for this one is thin beyond that.
Given the age of these systems, seals harden and cups swell or wear out over time, and a kit like this is the standard way to bring a tired master cylinder back to sealing properly. Give us a call and we'll confirm what it fits before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
