I have a 1980 280zx that i have just purchased. The problems i am having is finding parts for it (no surprise). But the brake booster is leaking and causing the brake pedal to feel normal till the end and goes straight to the floor towards the end. I am wondering if anyone has had this problem and if so tell me how you fixed it. Or be able to use a different brake booster setup. Thank you in advance (btw first post on this page. Pic is my car.)
