How to remove rear drum, stripped holes

[06YarisRS]

Back to getting the drums off. In our school shop the other day, a few kids were beating, prying, yanking, tugging on a drum to no avail. I suggested that they turn the star adjuster back. They did so and the drum came right off. I showed them how the ebrake shoes (this was a drum in hat rotor) make a groove on the inner surface of the drum and that's why it's hard to get the drum over the shoes.

So I was able to get the drum off.

The drum was spinning freely so I assumed there was no issue with the pads dragging or getting stuck on it so I didn't mess with the star screw adjuster.

I kept hitting the brake drum on the front face of it near all the bolts while spinning it around. Eventually I shocked it enough and was able to pull it off.

As for tightening the slug I was able to do it by bringing my wheel up close and under the brake and using another tool wedged in the wheel spokes add the hub to stop it from turning while I tightened down a nut to pull the slug into the hole.

I'm just glad that Toyota didn't design the thing so it is impossible to get the slugs out without doing a whoooole bunch of other work. There was enough space behind the plate to wiggle the slugs in and out so that was great.

Yes, There's a little depression in the backing plate that allows for easy stud removal. I learned this from other members when I installed the longer studs for my H&R 10 mm wheel spacers. I was lucky to have access to our school shop air tools which made seating the studs child's play.

Another quick school autoshop story: A couple of kids were experiencing trouble getting the studs out past the backing plate of a 1/2 ton truck. One of them grabbed the torches and cut a little 'window' in the backing plate to take the stud out. Inadvertently, he cut out the shoe retaining pin slot. That car got bolted back up without any ebrake parts and a backing plate had to be ordered. While things like this are unfortunate, can be costly, and happen because of a low teacher-to-student ratio, these are learnings that are firmly entrenched, generally not having to be experienced a second time.

Congrats on the getting the job done!

This is ticking me off can't find the access hole for the star adjuster on my yaris. It's a euro diesel from 07 so maybe that's the reason.
