ok, it's about 5:45AM, I go out and start my 98 C280, press on the brakes and the dreaded "Brake Pad Indicator" light comes on!

Ok, I know NOTHING about MB brakes. I have read all the discussions about pad types and I currently have the nasty OEM pads. I go to Fastlane to see what prices I will have to deal with and they ask me for the chassis type. They list:

-A 487047
-F 576240
A 487048-
F 576241-

I thought my chassis type was 202.029?? How do I know which one it is?

Also, are there other parts I need to order before I start this job? I have done a few brake jobs on American cars, so I know some basics.

Also, when the brake pad light comes on, how long can I drive it before it becomes a serious problem? I need to wait until Saturday, if possible?
