C3OZ-1126-B Used brake drum with the vintage casting look. Guaranteed to successfully be turned and not exceed the manufacturers inside maximum of 10.060". When we say the "vintage casting look", we mean with the proper groove and contours. Reproductions are fine, but do not retain the casting design of the original casting company. When looking for used brake drums, the rule of thumb is to find ones with a brake surface area of 1/4 inch more than the brake shoe width.
