MASTERCYLINDER ASSEMBLY 13MM 79-ON (SS BARREL)
A 13mm front brake master cylinder assembly with a stainless steel barrel, for later-model applications.
This is a front brake master cylinder assembly, 13mm bore, with a stainless barrel, built for the later-model catalog window described as 79-on. The master cylinder is what your brake lever actually pushes against — pull the lever and this unit pressurizes the hydraulic line running down to the caliper.

The stainless barrel is worth noting on its own. These bores take a beating from moisture and old fluid over the decades, and a stainless bore holds up a lot better against pitting and corrosion than the original mild steel ones did. If your bike's book calls for a 13mm master cylinder in this era, this is the assembly.
We show this part under the number 60-7163/13, and it also turns up in older records as 60 7167/13MM. Same physical part, just a different string in the ledger. Given the complexity of a hydraulic assembly like this, it's worth double-checking your bore size and lever setup before ordering, and give us a call if anything about your current unit doesn't match up.
