Brake Questions..ahh!
Ok. Well the W115 needs two things to be roadworthy. One: Good brakes, and two, an exhaust. Well, the brakes are being tough...
I first suspected the master cylinder. So I switched it with one from parts car. No difference: still stops, but extremely close to the floor. Second, tested the booster. Its working. I pump brakes, turn car on, and they return to floor. So all I can suspect is the lines themselves. The calipers are working, so what else could be wrong other than the lines? I bled them with the old cylinder, made no difference. Suggestions??

Are the flex lines old? They could be swelling under braking pressure....thats all I know of that could cause that.

There's likely some air in the system. Bleed and reverse bleed if needed with phoenix injector. Are the pads in correctly? If the pads aren't in correctly on one wheel, you will have the problem you describe. Does the pedal get firmer if you pump it once or twice?

No
The pedal never seems to firm up, and only grabs at the bottom, almost to the floor.

Hmm
It drops some, and not to floor. Exactly as you said.
