    78- Constant air in brakes

    I have a 78 C3 had the brake lines changed last year and brakes worked fine. Then randomly had spongy brakes so I replaced the master cylinder bench bleed it properly and bleed the whole system afterwards. Had no issues for 20 Kmart form brakes then went spongy again. (No leaks anywhere ether)...
