That's about it. I've never had mine off - just removed the lower pivot bolt to fold the caliper up to replace pads. But all that's left IIRC is the second sliding pin bolt, brake hose, and connector for the pad wear sensor.

One thing I like about these old Mercs it that the basic normal maintenance and wear part replacement tasks like fluid, filter, and brake pad changes are about and simple and easy as I've ever seen on a car.

Brake pad changes are especially easy because of the nifty pad holder. On a lot of cars you have to remove the caliper, load the pads into the caliper, then wrestle the caliper/pad assembly back on. On these old Mercs it's also easy to push the piston back in since the caliper is still attached. I just attach a hose to the bleed valve, open it up, and push the piston back in with a wooden hammer handle.

Make sure when you fold the caliper back on that the little leaf springs on the pads engage the caliper housing and don't get jammed in the inspection slot.
