Brake lining
Front wheel brake lining for the drum brake shoes on Triumphs from the listed catalog years.
37-1998 is a brake lining listed against the front wheel on Triumphs in the catalog years shown here, both the earlier type front wheel figure and the standard front wheel figure. This is drum-brake era hardware — the lining is the friction material that gets bonded or riveted to the brake shoe, and it's what actually contacts the drum to slow the front wheel down.

The older letter-prefix form of this part number is W1998, so if you're working from an early parts book or a set of NOS shoes marked that way, you're looking at the same physical item.
We don't have much more detail on this one beyond its place in the front wheel figures. If you're matching linings to a specific shoe or drum, bring in the old part or check the numbers stamped on your shoes before ordering — call the shop and we'll help confirm fitment.
