The frequency of change of rotors depends greatly on the type of pad used.
The more aggressive the pad the less life the rotors will have. Some places
advertise lifetime brake pads - that's because the rotors are being the
sacrifical item. *Something* is going to wear and if the pads are lifetime,
the rotors will not be. Having said that, the pads MB sells are a
compromise - they dislike dealing with constant complaints about brake
squealing so they sell soft brake pads - which give off a *lot* of brake
dust. But they don't squeal and the service dept doesn't have to constantly
explain why they are squealing.
As far as selling the rotors and pads as sets - I suspect what others said
about MBs desire to maximize profits has most to do with it. But there's no
need to replace the rotors unless they are below the min thickness when
measured with a micrometer (the easiest IMO).

Subject: [MBZ] Disc Brakes- Change Pads and Rotors?
Friends, why does MB sell the pads and rotors together- is it a good
thing to do these together? I was going to have the dealer do brake
pads and he only does them together. Is this a money robbing exercise
or is there some merit to changing both at the same time?

Gentlemen...
I decided to replace the front disks on the shaggin wagin, ordered the
new
ones from Rusty, and just for fun, since I hadn't done it in a while,
read
the manual. Do you really have to replace the "self locking hex socket
bolts" that say "one time use only"? When I did the job on my old 240D
(RIP), I don't think I put in new bolts. In any case, they are not
listed
on Rusty's web site, which tells me it's not a high volume item.
OBTW...Since switching to Mobil1, I'm up to 26MPG on my last fillup.
Admittedly, the fact that the A/C is temporarily dead may have added 1 or
2,
but I'm impressed. My daily commute is now 30 miles each way, all
freeway,
with less than 1/2 mile from the house/office to the on/off ramp.
