Im doing a brake job for a relative (rotors, pads, sensors) front and rear on a cls500. After swapping out all the rear parts, i start bleeding the brakes (2 man job, one man pump the pedal, one man bleeds the valve). After bleeding it several times no more fluid is coming out and the resevior is topped off. I hear the abs unit going off and i get a brake warning. Turn the car on, warning still there with abs light on. Turn off the car pump it and let the abs pump go off, turn the car back on and warning is gone and abs light is off. Is this normal? if not what am i doing wrong? thanks in advance

 

one more question, what is the bleeding order for this car? ive been going LR then RR
