Master cylinder leaking
I noticed a decrease in effectiveness with my factory drums brakes. When I checked the master cylinder brake fluid level I found the rear compartment about a third low with the front compartment about full. The main body of the master cylinder is wet with fluid and noticeable brake fluid drops on the short tubes and valve below.
Question is; can I just replace the master cylinder cover gasket? Or, should I go with a new cover & gasket, new snap cover wire, or possibly a whole rebuilding kit? NOS parts, new parts? And what vendors have the best parts, or can I go to Rock Auto, Heartbeat City, NPR...etc?
And then, keep in mind that sooner or later I want to change over to a power disc kit. But for now I need to stop the leaking.
I did check all lines and found no trace of a leak except at the master cylinder.
Thanks in advance for your thoughts.
