Norton Master Cylinder Assembly complete
Complete front disc brake master cylinder assembly for the handlebar-mounted hydraulic brake system.
This is a complete front master cylinder assembly for the disc brake setup, the unit that mounts up at the handlebars and pushes fluid down the hose to the caliper when you pull the lever. It shows up in the parts book under the Handlebars and Disc Brake Master Cylinder and Hose Group figure, which places it right at the top end of the hydraulic front brake system rather than in the older drum/cable setup.

The catalog record for 061938 only turns up once, tied to the 1971-1972 span, so we don't have a lot of cross-reference history on this one to lean on. If you're trying to match this against what's currently on your bars, check the casting and bore against your existing unit before ordering, and give us a call if you want to talk through fitment.
We don't have more detail on this one beyond what the parts book lists it as. It's listed as a complete assembly, not a rebuild kit, so expect the full body and lever unit rather than just seals or a piston.
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.
