Power Brake Master Cyl. ?

[Terry S]

I have a question for all of you carburator/brake system gurus out there.

The boost vacuum used to come off of a port in one of the runners in the stock 350 manifold (quadrajet). When I went with the edelbrock intake and performer carb, I plumbed it to the big fitting on the back side of the carb. I also installed a new check valve fitting where the hose plugs into the booster.

I was adjusting something the other day with the engine running and noticed brake fluid dripping out of the forward side of the master cyl. It's coming out around the cap at the rate of about 10 drips per minute.

The truck has set for about a year and a half at this point, so did I plumb it wrong or do I need a rebuild kit for the master cyl. or maybe just a gasket for the lid (yeah, right).

Thanks in advanve for your input.
