GL350 Bluetec and GLS580
These are the instructions I used on my Bluetec Quoted from someone on this board....
"Just replaced the rear brake pads in my wifes 2013 GL450.
Very easy, but a couple of different things that were firsts for me.
Figured I'd mention it here in case it can help the next guy...
Our GL450 has the electronic emergency brake, not sure if they all do.
If yours does and you are replacing rear pads, you need to go into the service menu first and activate the "Pad Replacement" selection to retract the emergency brake. Otherwise you will not be able to compress the caliper piston to accommodate the new pads.
The only other first for me was the brake pad wear sensor. On ours it was on the passenger/rear inner brake pad. Very simple to replace while putting in the new pads, but make sure you get the sensor when you buy your pads.
To get into the service menu:
Our GL450 has the push button start...
1.Get in car and make sure all windows, doors, hatch and hood are closed.
2.Press push button start once
3.Make sure odometer is showing on dash screen (or navigate to it)
4.Press and hold both the "talk" and "end call" button on right side of steering wheel.
5.Within once second of step 4, press and hold the "ok" button on left side of steering wheel. (keep all 3 pressed until service menu shows on screen)
6.Navigate down to "Pad Replacement" and select it.
7.Via menu...Put them in replacement position, then return them to normal once pads are replaced.
Once the "pad replacement" procedure is activated, you can recompress the caliper piston just like you do with any other brakes.
Anywho. Hope this helps someone.
I would have enjoyed reading it before I replaced my pads. ;-) "

They will be tight, over 100NM most likely, spec is 60Nm + 45 degrees, that's really tight. I usually use a long (almost 2 foot) ratcheting bar
