Master Cylinder Leak

Charlie7985 · Jan 28, 2020

Finishing up a complete rebuild of a 79 C10. Installed new booster, master cylinder, lines, etc. The reservoir keeps leaking from the lid at the back and running down the booster and onto the frame. Even though the lid and gasket were new, I've replaced them and still the same thing. Any suggestions?

Too much fluid???

could be an inconsistency in the lip on the master cylinder.
