Calipers & discs are bolt-on plug & play.

But wiring harness needs to be changed also, for twin wear indicators (std. has only got one). Also plug & play. Connectors fit.

(pictured old mucky 24V caliper...)
Std. dust shields fit also - but I may swap them over nevertheless...
And: NO WAY do 15" wheels fit. Even W211 7x16" ET33 steels are too tight to fit over the calipers... I'll investigate more wheel fitments as soon as I can get my fingers on them. R129 & 500E wheels will fit, naturally. 8x16" ET34 15-holes, 8-holes and 8x16" ET35 steels.
As per R129 I'll change to wagon rear calipers with 278x9mm solid discs. Dust shields (I have a Coupé w. 258x9mm std. rears) will need replacing (PITA!!) or modifying. 278mm discs don't clear the std. sedan/coupé dust shields. Unless the vented or non-vented 278mm discs are allready fitted (M104).
Result: I need to throw up when I stomp the brakes... But they'r still not "aggressive" like modern brakes and allow very comfortable breaking & good dosage of stopping force. Very nice!

I had to "carefully" modify the firewall a bit... Brake lines need bending to fit. Master needs to be installed before you tighten the servo - servo needs to be tilted a bit to insert the master cyl.
