(34211116477) - Brake Shoe Mounting Pin-1600/2002/2002tii (66-76), 320i (77-83), 318i (84-85) (Genuine BMW) (4 available)

BMW part number 34211116477 (superseding older part number 34211111857) is the direct sibling to the spring you just asked about: it is the Rear Brake Shoe Hold Down Roll Pin. This steel nail-style pin slides straight through the rear wheel backing plate from the backside, pierces the brake shoe, and locks onto the top-hat clip after compressing the hold-down spring to keep everything mounted. Because it pairs identically with the 34211116476 spring, its vehicle fitment profile covers the exact same vintage US models from 1966 through 1985:
