I just changed the hydroboost because it was leaking on a 2000 Chevrolet k2500 with 454. Power steering and brakes worked fine for a few minutes after I reinstalled. Then I lost power steering and brakes. Has anyone else ran into this? I followed the bleeding steps multiple times now and still no luck. I plan on tearing into it again tonight. IT is a pretty simple swap so i dont think it was anything i did. I know many other trucks have the hydroboost so i figure someone has seen this before. Any help would be appreciated
