two-man pedal pumping bleed
A combo of the last two - pump/hold pedal while an assistant opens closes bleeder screw WHILE the pressure bleeder is attached to reservoir is quite effective.

The trick is to pressurize the brake system to 20psi, crack open the RR caliper bleeder screw, bleed until zero bubbles (can take 10 mins), activate the ABS MODULE, press on the brakes 5x, continue to bleed to flow out the air that was trapped in the ABS block, repeat the ABS and manual brake activation until everything is clear and free of bubbles.
Move to LR, RF and then LF. Road test
Rebleed and you should be good to go.
Air seems to like being trapped in the RR and RF channels for some unknown reason.
