Help it is grinding bad

No Idea When things get old (these girls ARE old LOL) and when parts start being swapped



Here's what I'd do. Determine FOR CERTAIN That the shoes / brake hardware will work OK

Determine for certain the drums are not hitting the shows on the inside face of the drum

If you are absolutely certain that the drums are hitting the backing plates and that the backing plates are 11" I'd find a "friendly" shop that turns drums and have them turn off some of the outside edge of the drum
