Brake Stuck After Bleeding? 3BG PD TDI

I would like to share a surprising observation:

After two attempts to fix the sticking front left brake (hot rim during highway driving, now okay), I had to bleed the brakes. After working on the last front left wheel, it turned out that both front brakes were completely seized, and the wheels couldn't be turned.
Removed and reinstalled the ABS and ESP fuses, disconnected the battery, checked the pressure relief valve, and then there was a loud bang and a big problem on the side street in the new development area.
My son and helper said, "Hey, there's a plastic part near the brake pedal, and it doesn't look like it belongs there." What the...?

Kurz und gut, über dem Bremspedal ist eine dreieckförmige Abdeckung ohne Befestigung am unteren Ende. Wenn das Bremspedal zum Entlüften durchgedrückt wird, hakt es zwischen Pedal und Hebelstange ein, Wirkung wie Feststellbremse. Sieht fast schon aus wie design by purpose. UngIncredible.

Perhaps this information will be useful to someone.

Never seen it before, but thanks for the info . Is there a picture?

Best regards, Rainer.

..try to make one soon, when the mountain of work has been cleared .

This is what a brake looks like when it's ready for operation.

Evening.
That's probably a retaining clip from the trim . It shouldn't happen if it's properly installed.

It was like that from the factory. I didn't do anything or install anything. In this case, four eyes really saw more than two.

I also think so . Nevertheless, thank you for the feedback.

I've received help from you before. That's why I'm happy to return the favor whenever I can.
Thank you all.
