E450 Rear Brake Pad Replacement - long post w/pics

Just an update. Finished right side rear. Was going to try and get the left side rear also today but ended up spending a lot of time repairing a ride-rite airbag stabilizer. What a hassle, but it holds air now. Brakes went very well, the new pads were a lot thicker than the ones I took off. Appreciate all the help and insight, hope to finish the rest of the wheels this week and bleed and flush the system on Saturday.
