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.

The vacuum check valve should have very little resistance to airflow in one direction (towards intake) and complete blockage the other way (towards booster) this is to protect the booster from backfires. If the check valve is working properly an is also properly installed you should need only moderate vacuum to operate the brake booster. They don't fail very often so are easy to find at dismantlers, not to difficult to replace either. Hope this helped. H.M.
