I was going to do a full DIY write up with high def pics and what not but I didn't have enough time today. I can always just redo everything ya know.

But a few notes for those that havent done the job.

If you don't have a 1/2" drive extension.. get one. The top bolt for the caliper is a pita to remove with a breaker bar.

5mm allen 3/8" drive is useful. Make sure the disc is flush when putting the new one on.

Other than that its very very straight forward. If it wasn't for that bolt on the calipers I would have been done in 30 minutes. The W124 chasis is 100000 times easier than a w123, 126, 115, etc to remove the disc.
