My breaks wont work after changing the front rotars, calipars and pads. I bleed all four breaks starting with the back passenger side then back drivers side then front passenger side then front drivers side. My breaks still don't work. What am I missing?

As a general rule, if you have ABS you might have to cycle the pumps and valves to purge the old fluid out of the unit. This is either done via a dealer scan tool, a purge valve/bleeder valve on the ABS unit, or a less than ethical way. Drive your car and heavily engage the ABS, you know what I'm talking about.
Then you will need to repeat the bleeding process that you have already done.
Normal non ABS brakes, bleed once.
ABS brakes, bleed, cycle then bleed again.

Tamisweeney, You don't mention what the year or make of the vehicle in question is but I am going to assume that it does have an anti lock braking system. (ABS) You need to check the ABS module for any bleeders. When the calipers were replaced did all of the brake fluid escape the system? If this is is the case then you need to be sure the master cylinder is full with brake fluid and bleed the system once again but this time start with the bleeders on the ABS module. The bleeding procedure you mention here is correct so after the the ABS module is bled rebleed the individual wheels using the sequence making sure that the master cylinder does not get too low in the process. Check the master cylinder often while bleeding. Good luck with this.
