My bad ... W123.

The safety gains or losses are really not an issue. A correct 6:1 pedal ratio with a manual system is probably more responsive than the 1983 set up I got now or any one of us. Secondly, it does remove "some" parastic drain on the drivetrain. How much is a seperate can of worms. Third, it cleans up, simplifies, and makes the system a little more rebust.

So, did MB make a manual brake system for the W123 or something which would be clearly adaptable without a bunch of R&D.
