Have someone hold the button in on the combination valve while you bleed it. Close all bleeders, start at right rear. Open RR bleeder, have some one pump the pedal while you hold your finger on the bleeder, and the comb valve button is pressed, do not allow the master to drain out while doing this! You will get fluid eventually, then bleed rest of the system, RR, LR, RF, LF.
