REAR MC TRI76- BY GIRLING
Girling rear brake master cylinder assembly, PN 60-4401G, for later Triumph twins and triples with a hydraulic rear disc brake.
This is the rear brake master cylinder assembly, catalog number 60-4401G, made by Girling. It's a hydraulic component, so it belongs on the later machines that got a disc rear brake rather than the older drum-and-cable setup. The description in our records ties it to Triumph twins and triples from the mid-1970s onward, and the assembly also shows up under the older WW27482 number in earlier parts listings.

The master cylinder is what turns pedal pressure at the rear brake into hydraulic pressure that gets sent down the line to the caliper. On these bikes it's a separate unit from the front system, so if you're chasing a soft or spongy rear brake, or fluid that won't hold pressure, this is one of the parts to look at.
We don't have much more detail on file for this one beyond what's in the description above. If you're trying to match it to a specific model or year, give us a call and we'll help confirm fitment before you order.
