Repeatthis procedure in the sequencerear left / front right / front left. This will re- move all air bubbles (from the primary circuit). Note Also carry out this procedure if the brake hydraulics was largely empty or if after bleeding residual air can be detected by excessive brake-pedal travel. Caution: In vehicles with high mileage or in old vehicles, double the pumping cycles and use --- only half the brake master cylinder stroke (dam- age to the brake master cylinder could occur / primary boot damage).
