Brake booster bad?
Brakes hard to use, can hear hissing noise inside when applying
Is there a vacuum line inside?
Haven't checked check valve yet.

There is a seal where the pushrod goes into the vacuum can. It's bad. I've got the same thing in my 2000 WJ but only on heavy braking. I've lived with it for 5 years without changing it and it works fine on everything except panic stops. The braking action is okay, it just makes a whistling sound. Yours must be worse if the brakes are hard to use.

Internal parts are unavailable. You're going to have to buy a reman. It's a safety issue.
rockauto.com has an ACDelco reman for $84.79 w/o master cylinder + $10 core + shipping just as an example.
