Replacing

When installing new brake drums, do not refinish the braking surface. These parts are already at the correct level of surface finish. During manufacturing, weights are used to balance brake drums. Do not remove these weights. After you refinish brake drums, or when maintaining wheel balance is difficult, check the drums for balance. They can be checked on most off-vehicle balancers. If found to be out of balance, replace the drum.
