New master cylinder is hissing. Fittings are tight, no leaks, but it's hissing when depressing the brake pedal.
Also, the pedal travels further to stop then prior to the replacement.
I don't know if the noise is normal or not; never listened to the other one.

UPDATE: is the hissing a bad seal inside master, or the booster making noise? I have never had someone push the brake pedal down while i was listening unser the hood.
