So, initial bleed of brakes and test drive did not go so well. Spongy pedal that requires pumping to keep pressure up and brakes somewhat working. Multiple conventional bleeds does not expel any air or improve pedal. Did the following:
Adjusted rear drums a bit tighter, helped.
Checked pushrod. ok...all the way out.
Clamped/pinched all rubber hoses closed and pedal went hard...this is good.
Removed rear brake clamp, pedal stayed firm with a bit more travel. Good.
Released one front side clamp, pedal got soft. Not good
Released second front side, pedal got softer still. Not good
Bleed again, no joy. So, I was thinking air trapped in hard line bends that are above fluid level. But, clamping rubber lines says this is not the issue. Front calipers move/flex slightly upon applying brakes...could be a contributor.
Now I am thinking I need residual valves for front calipers to prevent fluid drain back to lower master cylinder. What do you think? Anything else I should do or check?
Going to call CPP on Monday.
