My master cylinder was leaking on my 190D 1985. I replaced with one from a parts car and am trying to bleed the system. Hooked up my bleeder and brake fluid is squirting out the two valves on top. See pic. I pulled off the rubber caps. What are they for? Can you get the reservoir off the master cylinder . I could use the old one. But why are these valves bad and can i fix them?

Thanks
