When using the Motive Power Bleeder how much brake fluid do you usually put in when bleeding the brakes? The capacity of brake fluid in the c280 is only .5 quarts according to the owner's manual. I realize some new fluid will be wasted in the exchange but if done in a reasonably skilled way, how much is needed in the Power Bleeder? Can you refill the Power Bleeder, say after you complete the bleeding at one wheel but before you go to the next? Thanks for this and any other insight on this procedure.
