How to replace brake discs/rotors and pads
you got a spare set of pins just in case? or are you going ***** out and hanging low

If you've got a supplier near you i'd get a set of shoes as well if you haven't ever had the rear discs off - that way you have them if they're worn and need replacing, and can return them for your money back if not. Saves having to pull the discs twice and really you should do them at the same time....don't ask me how I know....

Do your rear brakes with key in accessory position and parking brake off. Listen to your radio.
Full disclosure: My CL is first Mercedes I've owned with Keyless Go. First thing I did is pull the start button off so I could use the key in the switch to start. That's how I find "accessory position." Maybe it's in the owners manual how to do it with the button installed.
