At my last B Service, the dealer reported I needed new rear pads and the rotors were fine.  But at the asking price of $500 plus tax, I turn him down.  I never have done brake work before, but at that price I was willing to try. 

I used this link at my guide: http://members.aol.com/dominic888/howtoreplaceml320brakepads

The the rear pads uses 13 mm bolts, after you remove them you must pull on the boot to release the caliper.  I had to use my large flathead screwdriver to carefully pry the caliper off.  The rest of instructions in the guide is the same.

Dont we all. When my ML was in for the radiator clamp the dealer called me and was like you need the following:

Sparkplug change 500$
Oil Change 90$
New windsheild Washer Tank 300$

I laughted at them and said, just do the service, ill be there in a hour to pick it up..

John looks good! How long did it take you?

I took my time, the Jack and stands were new.  Figured out the best place to use the jack and place the stands.  Got stuck on removing the caliper, the guide didn't say after removeing the bolts to pull back on the boots to release it.  Had to use the screw driver to slowly pry it out.  The second side was easy after that.

It took me about 3 hours to do all the work and bed the pads.
