Bought an NOS brake master cylinder about 6 months ago, Worked great after reusing the old tipping valve.
Now I’m losing brake fluid at an uncomfortable pace.
Visible leak at the connection between booster and master.
Do I just get a rebuild kit and install, or would the bore sizes be suspect?
I do have spare masters that need re-sleeve, but I’m hoping that perhaps the rubber on the seals had become brittle in storage.
At this time I’m not interested in the series 3 master mod.
Any advice is welcome.
