just get yourself a 3 foot piece of fish tank hose. put one end on the nipple and the other end in a clear glass jar. put about 1 inch of brake fluid in the jar, so the hose does not suck air into it. open the nipple nut and pump fluid into the jar. Once the bubbles quit coming out, close the nut and your done.
Wilburz, Good suggestion, I never thought about doing it that way. I also start at the rear first then do the right front then the left front.
