I think I already have air in the lines of my XJ b/c the fluid was so low b/c i did not catch the bad wheel cylander fast enough. I replaced the cyl (sp) and I am trying to blead the brakes but they don't seem to be working right. I have heard, and read, that you need to do something special with the pedal when you do this but I think I already had air in the lines. The ABS doen't work anyway as there is no tone ring on one of the axles in the rear. What can I do?
