Someone did this to my graymarket 1984 300TD and I don't much like it because the brake pedal i so soft it just feels....'wrong' somehow although the car stops on a dime .

I didn't read the whole thread, so I don't know if the OP had positive results from this modification. My experience: I put a W116 brake booster in my friends TD. He thought it would be a nice upgrade, but it turned out to be more of a hassle than it was worth. The brakes were no better than before. He even had the booster rebuilt, but still no improvement in ease of braking or anything else. I have always thought that these cars (W123, W126 etc) had excellent brakes, so no need to modify them in any way.

I have a W126 booster in my 1983 300D, upgraded it and the master cylinder when I upgraded to W126 front brakes. Everything fit well and the car stops great.
