I am replacing out the axle seals, rebuilding the wheel cylinders, and just trying to get all the gunk off of everything. Now, once I cleaned up the brake backing plates, I notice some heavy marring/gouging on the points that the brake shoes articulate with the backing plate.
Question 1: How does this happen?
I already have a low opinion of the PO's mechanic. So, wondering if there is a cause that a more seasoned mechanic knows about.
Question 2: Can I build these pads back up with my wire feed welder and then grind them flat and then sand smooth? Or should I just go to the junk yard and get another backing plate?
This is more than wear and tear, it is downright gouging and grooved.
