Hey guys,
Sorry I didn't get back with you for a month or so--life gets in the way sometimes. Update: I tested the MC by placing plugs in both outlets--very firm pedal tells me the seals are OK. While lines were off, I looked for signs of residual check valves and found none. I purchased and added 10 lb check valves for front and back, then bled the system again (first with engine off, then with engine on). What I found is that now the brakes on the first push of the pedal have almost no resistance (just before going to the floor a little, just enough to slow truck down but not stop it). The second push, though, has perfect resistance and great stopping power--so I can stop but only with the second pump of the brake pedal (not great reaction time, that's for sure).
Any ideas?
The only thing that I can think of at this point (from all that I have read) is that the new brake lines may have a point where the arch up and may have some air caught in them that is not coming out with bleeding. I'm just about to give up and convert to a system on the firewall, but hate to not be original (with MC under the cab).
