On star hubs the brake drum is fixed by five lug bolts to the hub flange. The brake drum must not touch the spoke flange on the hub. The cast brake drums will break — especially when it is distorted by tightening the bolts. Manufacturing tolerances (aftermarket brake drums and hubs) can cause the drum to touch the hub. Before you tighten down the lug bolts, you will want to check for sufficient brake-drum to spoke flange gap and — if not present — use one of these shims.

In order to function properly, the brake base plate on which the brake shoes are mounted must not touch the brake drum. If, during wheel installation, it is found that the drum is rubbing against the base plate, the base plate must be moved outwards using these spacer washers on the axle sleeve.

Special countersunk socket head bolts to mount the brake drum to the wheel hub.
