Thomas, once again, a clear, organised, and methodical illustration.
I'm telling you man, you might be a thoracic surgeon, or a nuclear physicist, but you may have missed your true calling in life! These illustrated guides are works of art.
I was waiting for Bert to show up in the slides, and notices he merely pronounces his satisfaction in slide 62. He didn't make any other appearances throughout the job?
My only suggestion might be this - when you show the bleeding of the brakes at the very end, put in a recommendation that complete brake fluid replacment might be necessary as Mercedes requires brake fluid to be replaced every two years.
Because of this, I usually go ahead and flush out my brake fluid when doing front or rear brakes.
