My brakes were not working properly so I have decided to take a look on that - well, ended-up replacing shoes, springs, some brakes lines and hoses, etc.
It has front disk and rear drums. The reason I decided to change it is because the pedal was to heavy and the car was taking forever to stop.
Ok, after replacing some of these parts, the issue is the same. Since I have the car I have never changed or worked on the booster or master cylinder so I was wondering if the booster is bad.

Any thought?

Sounsd like a booster issue, but I'd look at the vacuum feeding the booster first. Could be something as simple as a stuck check valve (nipple that plugs into the booster). Replace that (most parts stores should have one on the shelf) and see what happens. If it does nothing, check your engine vacuum. You need at least 15" of vacuum at idle to power the booster, preferably more.

Thank you - I'll try this next week when I work in the car again.

Finally I was able to work on the car today.
There is vacuum feeding the booster (15 at idle) and the check valve is ok.
So seems that I'll have to replace the booster - is it repairable or should I go directly to a brand new one?

You are MUCH better off having yours reconditioned- They are superior to the new imitation boosters. Glazier Nolan can get that done, or you could try an internet search.

nd yeah, as you are beginning to suspect, a heavy pedal means you are loosing boost power.

I agree. I work at Napa and our reman boosters are only so-so. I'd guess maybe one in ten come back to us DOA.
