Bleeding is a bitch - but I now have a solid front brake. What I learned about bleeding (when starting from a bone dry, rebuilt system):
Bench fill the brake line, holding it in a U, fill one end until it comes out the other.
Use teflon tape on the caliper connection of the brake hose and the bleeder valve.
Pre-fill the caliper.
Connect the brake hose to the caliper and a clear hose to the bleeder, fill bleeder hose and blow it back thru the system.
Do the thumb trick - hold your thumb over the banjo bolt exit of the filled master cylinder and pump until you get squirt. Immediately connect the brake line.
Pump and bleed for a few cycles until the pressure is maxed.
