I need some help on my 82' 280ZX IM having problem with my brakes. the pedal feels hard, as if I didn't have power brakes. even if I push very hard, I still CAN'T brake as it should, I don't think I can even lock the wheels if I sped up fast enough and slammed on the brakes. IM afraid to drive it in real traffic until I figure this out. I thinking it might be the brake booster. I DID check the vacuum and it is strong, I don't have a vacuum gauge, but it still seems Ok to me. the one way valve also appears ok, but IM not sure if enough volume is going through the valve. if I blow through the opposite end, it does close.
