Well after much reading and research, and thanks to all the Brickboarders that came before me, today I finished my first brake job on my S90. I had not performed a break job, in over thirty years, and it was by far the most complete one. Replacing the pads (front and rear), rotors (front and rear) and emergency brake shoes took me over twice as long as it would have taken a professional, but at the end the personal satisfaction and knowledge gained was well worth the time. The saving in the labor cost and elevated part prices from the mechanic did not hurt either. Again thanks Brickboarders, once I figure how to upload pictures, I will post the job in pictures.
