Brake Drum: Notes
WARNING: This page is about a different car, the 2004 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The maximum allowable diameter of the drum braking surface is indicated on the drum outer edge.
Generally, a drum can be machined to a maximum of 0.06" (1.52 mm) oversize. Always replace drum if machining would cause drum diameter to exceed the size limit indicated on the drum.
