    Actually, two pictures, with two things wrong.

    First is a giveaway: My working conditions.

    Secondly, despite the restricted space (there's even less room on the driver's side where I had to repeat the same work, and took this picture), I was able to tear down the rear brakes to find this. I took the picture to document the orientation of the parking brake doohickey assembly, since it came apart on me on the passenger side . Anyone see a problem despite the blurry picture? (Not you, Miltonian :))

    The rust or the lack of brake shoe material?

    Two views of this thread and I already get the correct answer. I think we have a ringer here.

    Yeah that stuff turns to dust and gone. Likely from people driving on ebrakes as a result of improper adjustment :)

    Show us what the "drum" inside the rotor looks like. A little scored?

    More than scored, Jeff. The drum surfaces were ground down enough and recessed such that fresh and properly adjusted shoes would have kept the rotors from coming off the hub. Just as you described during my visit. So, thanks again for the fresh rotors!

    The bare shoes aren't worn down as bad as the rotor. I think I can get the shoes relined in Kevlar by an outfit in Seattle that did the shoes/drums on my vintage race bikes.

    So satisfying to have solid parking brakes now!

    They came from the factory improperly adjusted and some still are. I readjusted every single parking brake on every car I ever did a pre delivery inspection on and check and adjust every car I service yet many I see still have not been done. That includes going back to the TR/328/Mondial when they started using that system. How many times do those cars need to get serviced before someone adjusts the brake? How many decades do they need to be on the road with people struggling to get them to work before it gets addressed?

    You are not the first pro tech to tell me that - thanks for confirmation. Much appreciated.

    Don't know but when I got my last 355 I just addjusted the parking brake myself.

    Sounds like the same concept with the sticky interior parts - a problem that Maranello didn't/won't correct, and instead continue production with the same problem.
