It is easy and straight forward on our 97 C280.

A pad/disc spreader would come in handy for the rear as the pads pulls out straight from the rear of the caliper and slides in same way after removal of a pin and retaining spring.

I would presumme it is the same on your.

But make sure you have a 17mm allen key to loosen the locking pin of the front caliper. This is not the most common size at least in my tool box.
