Open the bleeder on the front and let the fluid flow, but keep watching the resivor so it doesn't pull air, next the other side.
Then pull hand brake in about 1 inch and let snap back open while watching in red, you may see some residual bubbles coming out. If not give it 4 full pumps, and you should have pressure. Bleed 1 more time on each side doing a half bleed,just crack the bleeder and apply enough squeeze untill starts to leak out then close. And you should be set. They are a pain in the a$$.the 400 love a couple pumps now and then to build pressure
