Hard brake pedal

I had this trouble too, usually on a cool morning I would start it up, hit reverse to back out of the driveway and the pedal would be hard. After a few stops it worked fine.
After a month or so it started doing it more often at different times, then after about 6 months or so it stayed hard when trying to brake, it required a fair bit of pressure to stop so you really had to plan ahead.
During this time I had replaced vacuum lines, pcv, orings, upper and lower intake gaskets but still no joy.
I ended up having to replace the vacuum booster. It was not pretty. Master cylinder had to come off, bolts hard to get to, stuff at brake pedal etc. It is a little tricky but not impossible. Took me and another person about 2 hours I would guess. I am certain I could not do it without help. Needed to twist the booster and have someone on the inside snake the rods in and work them in place. I had a box or something outside the driver door for my body to rest on while I was on my back or side trying to wrangle everything back in place and get the bolts secured.
