I think I know what the answer is but I am looking for input from some confirm my suspicion or to correct me.
Here is the back story. Brakes started acting funny on my '92, at first had to pump them a bit and after a few days to a week or so I had to start pushing on the pedal real hard to stop. Found some issues and have replace a wheel cyl, drivers side rear brake line and the master cyl. Master cyl was bench bled, all brakes bled well all 6 or 7 times that I bled them. No leaks. No air in the system. At no time did the system run dry so I can not see the rabs being an issue.
What I am encountering now is a very stiff, almost like manual brakes, pedal and I am hearing a hissing noise coming from what seems like is under the dash. I am leaning towards it being a power booster issue. Do people concur, and if so are there any parts that can be replaced or do I have to replace the whole unit?
2 things I forgot to mention, I do not recall hearing the hissing before I replaced the master and the old master was not leaking back into the booster.
