Rubber boot, master cylinder
Rubber boot that covers the master cylinder brake hose fitting on Triumph disc-brake front ends.
This is the rubber boot that fits over the front master cylinder on the hydraulic disc brake setup, part number 60-4186. It's a small cover piece that sits at the brake hose connection, keeping road grit and moisture off the fitting where the hose meets the master cylinder body. It shows up in the FRONT BRAKE section of the parts books, so it's tied specifically to the disc-brake front end rather than the older drum/cable front brakes.

Our records show this number superseding an earlier factory part, 60-4626 — same physical boot, just an older number if that's what's printed in your parts book. It's a low-cost item that's easy to overlook until it's cracked or missing, at which point the fitting underneath is exposed to weather.
Catalog appearances for this one run from 1974 to 1978. If you're not sure whether your bike's front brake setup takes this exact boot, give us a call and we'll confirm before you order.
