Customer calls and says he has a problem with a brake backing plate. He was driving down the road, it popped, wadded up the parking brake shoes inside and he wants a free replacement because the part is obviously defective.
I tried to explain to him that isn't how they work. They can't self apply. There are only two scenarios where they can do what he has going on.
The first one is if you apply the parking brake and drive off in 4 low. That snaps the anchor pin off at the top and the shoes and hardware get wadded up like this. (my parts that I broke)
The second way is if the wheel bearing dies and allows the rotor to move up against the shoes and put enough pressure on them to make them catch and get wadded up.
Other than that, nothing can cause them to do that and there is no defect either I or my brake buddy can think of that would create the problem.
He replies in an email that the backing plate is the problem and he's going to leave the appropriate reviews if he has to purchase another one elsewhere. I tell him I have no issue sending him a goodwill part, but I won't do it for any other reason and if he doesn't find the actual problem that caused the mess, it will happen again and that I didn't believe anyone had the balls to ask for 2 free backing plates so they better figure it out before they install the new one.
My favorite part is I'm trying to explain how they work and the first thing he says is he is not mechanical, but then goes on to argue the mechanics with me.
