Wear on brake shoe due to parking brake lever

[rreegg]

The exisiting shoes and hardware are being replaced, believe the existing shoes to be from 2018. The shoe surface is in good shape but the contact point with the parking brake cam is worn out and mashed on the rear shoe - see pic. Anyone see this before? Is it common and just due to cheap metal on parts store shoes?

I would expect the parking brake to grab more if not worn out, I need to push the parking brake all the way to floor for it to do anything

This might be a slightly better pic

Some brake shoes being made are defective by design.

I bought expensive shoes (for 85 E350 dually) in early 2020 but didn't get around to installing them until October 2020.

Note how the upper ears are on the shoes as it goes around the round piece, where the parking brake arm mounts. They're short and uneven.

A top down view. The tab for the parking brake wasn't able to push the ears, instead was jumping up on top of the ears.

Now look at these properly made, O'Reilly budget brake shoes. The ear sticks way up, like it should.

Cubey hit the nail on the head. Check out this other thread detailing this issue:

The problem with new brake shoes and the parking brake.

Garbage mechanic sent me some pics of the problem with the parking brake and new brake shoes. I'll post them here, along with his comments on them. (I'll put his comments below the pics.) Then he can come in and answer questions, or make further comments, etc. I think I'll post one picture per...

Nice thanks @Cubey and @ROCK HARVEY had half a mind to weld them up a bit but didn't go through on it yet, nice to see some precedence on that. crazy this is an established issue but not surprised too. fudge though too

The cheap bonded O'Reilly shoes with lifetime warranty worked great, vs the expensive riveted ones that were made wrong. So... yeah. Didn't have any problems with bonded shoes on a 27ft motorhome being driven through the mountains, and towing ~1500lbs without trailer brakes.

Awesome that’s what I just put on. So far so good parking brake grabs tight after just a few maybe 5 clicks

+1 on that. I had the fancier and much pricier NAPA riveted shoes on my pickup, kept locking up the rears on dry ground not even trying... after tons of adjusting and thinking I just got the O'reilly ones that worked perfectly out of the box and no issues since.
