Brake upgrade question?

Repairing your monovalve will have a negligible effect on brake performance!!!!! LOL

Seriously I know absolutely nothing about MB brakes never having the opportunity to work on mine yet. Honestly I am one of the newer members of this forum and my actual experience is fairly limited to my 87 SDL and the couple of issues I've had and have with it. The first repair I did was the monovalve a couple of days after I found this forum. I saw the FAQ/DIY site as an opportunity to share the little I did know with others who could benefit from my limited experience. I am greatly indebted to all the individuals who share the incredible breadth and depth of wisdom and knowledge not only related to these fine automobiles but in many discussions on an enormous range of subjects.

I’m sure that someone with greater knowledge than I will eventually read your question and perhaps have the exact answer you need, until then Good luck!
