BRAKE DISC 4 HOLE CAST
A four-hole cast Triumph brake disc used on front or rear wheel setups.
This is a 37-7175 brake disc, a four-hole cast disc that shows up in both the front wheel and rear wheel sections of the parts book. It's a factory Triumph part, and the cast disc design is the type used before Triumph moved to a different disc pattern later on.

Because this part appears in both front and rear wheel figures, it's worth confirming which end of the bike you're ordering for before you buy — the catalog data we have doesn't spell out whether a given listing is front-specific or rear-specific, so check your own wheel and hub against the four-hole mounting pattern before ordering.
The catalog entry doesn't give us finish detail beyond "cast," so if you're trying to match a chromed or unchromed disc, compare against what's currently on the bike rather than assuming from this listing alone.
