1975 brake master cylinder
I have been having issues with brakes for while. I am used to power brakes, but my corvette does not have power brakes. I am okay with that, as long as the brakes work as they are suppose to.
What I am expecting the brakes to do: Lock the wheel when I go really hard on the pedal, and I mean HARD.
What the brakes actually do: will slow the car down but no where as fast as it should. and no locking of the wheels.
I have changed all brakes pads, all calipers, rotors are in good condition. Its been bled multiple times. There are no leaks in the whole system. I have no idea what the issue has been.
What I have noticed is that when I go really hard on the brakes, the brake oil seems to spill out of the master cylinder top. its sealed really tight. So what I am trying to figure out is is the top cap a problem. or am I having to push too hard on the brakes and actually should be worried about system bursting?

you need a new master cylinder gasket but that has nothing to do with the primary problem. When you step on the brakes really hard does the pedal go almost to the floor or does it remain firm?
Was the master cylinder bled?
You could also have a worn out master.

how do I tell if the master is worn out? Any specific tests I can do to find out?
