In disassembling my brake booster (1966 230SL), I found some old brake fluid in the chamber on the master cylinder side. It was very brown, as though it had been there a while. I don,t see any indication of leakage on the master cylinder so my guess is that it was leaking at some point and was repaired. It also wasn’t losing fluid before I took the cylinder off of the booster. Just want to be sure that there shouldn’t be fluid in this area? Correct?
Probably should rebuild anyway.
Thanks,
Harry
