Are you using a pressure bleeder? Highly recommended.

If not, be sure that both chambers of the reservoir are full before you start pumping and are not dropping and allowing air into the system. One of the chambers takes a few minutes to fill and if you start pumping right after adding fluid, you get air in the lines.

Also, at the bleeders, be sure to use a clear hose and a good light to be sure that you're not getting tiny bubbles in the fluid.

And you did go RR, LR, RF, LF, didn't you?
