Brake booster/MC problem
 
I've driven my truck around the block and notice that there is brake fluid coming from between the master cylinder and the booster. Is there suppose to be a gasket between the two. What kind of problem does this indicate? Push rod adjusted to much?

Sounds like your MC has a leaking seal. Check fluid levels. Either rebuild or replace.

No fluid should come out the back ,the piston seals are worn.

make sure the leak is not a bad gasket seal on the cover of the master cylinder// i see lots of the new replacements especially the chrome ones leak

Also check brake line fittings and make sure the are not leaking.
