When I hit the brakes every other time the anti lock brakes system will engage causing me to stop on the brakes to stop. brakes have been bled.

if brakes have been bled then you probably have air in ABS unit or something is wrong with the ABS. have a mechanic bleed the brakes with his scanner as he can open the valves on the ABS unit and bleed it like that. it takes a specialized scanner to do this.
