That sucks. I would imagine Slon ran one batch of brackets that were all the same. Mine was plug and play, no bracket modification needed.

Regardless, you've gone through enough regarding these brakes, sorry you ran into more issues.

Is this person running the 380mm F8x rotors? If so, he needed to use the included spacers.

Is he using the correct brake pad size?

Edit: That brake pad shape looks like it's for the 380mm setup. Pad shape D1426, so make sure it's getting installed on a 380mm rotor with the bracket spacers. Your second picture should show a spacer between the caliper and bracket.
