Brake Drums Backing Plates

3 products

Brake drum backing plates from MCS for 1941-1972 Big Twin restorations — Knucklehead, Panhead, and early Shovelhead. Made to original spec so they bolt up to factory hubs and linkages without modification. The kind of part worth ordering early in a restoration; finding a usable original takes longer than the rest of the bike. Pair with matching shoes, springs, and hardware to make a complete drum brake assembly.
