Default Brake Booster

I have an 84 and having issues with the brake booster. This is the 2nd one and cannot get any response from it. It seems like the car stops only when extreme pressure is applied to the pedal. Plenty of vacum, new calipers, rotors and master cyclinder. Tried bleeding and no difference. Any ideas?

Not good.

What about the brake hoses? Are they original? Are you sure the MC is good?

Yes the MC was new with all the other parts installed. New pads also and braided cables too. Calipers were from Ecklers rebuild center, and I may have some doubt about their quality. I ll let you know what I find, Thanks

My 1990 brake booster cracked at the vacuum port going into the booster after 18 months. I have recently located and purchased a metal booster. I have an aussie made booster and apparently they do this often.
