Need some brake guidance
I am not terribly unfamiliar with working on vehicles, but my '79 240D is totally new territory to me. I went out to start a front brake pad job while ago ran across something new to me. Looking at the inside of the caliper, it appears there are four 15mm bolts that hold the calipers together. After a little assistance from a breaker bar I was able to get them loose. As the outside started to to slowly separate from the inside, brake fluid started seeping out. At this point I realized I was dealing with a different animal than I am used to and decided to come ask you guys...
a) Is this normal? b) Do I need to pinch off the brake line during this process? c) Any other surprises that I need to be aware of?

You dont need to take the caliper apart to change pads.

You don't need to remove the caliper to replace the pads. They are quite different form most domestic vehicles. Remove the two pins at the rear of the caliper and pull the pads out. Way easier than a Ford or Chevy.

Wow... I can't believe how easy that should have been. For what it is worth, there was no visible separation of the caliper. I had only gotten the bolts backed out enough that brake fluid was showing along the crack. I went ahead and replaced the pads, bled the brakes, and nothing feels out of order. Would you mind expounding on the statement that the only safe thing to do now is to replace the caliper? I don't mind that if I must, but I would like to better understand why. Thanks.

Because they have been held together in that position for 29 years. Breaking that bond means it will likely never seal completely.
