I just replaced my master cylinder, brake booster, hydraulic lines to master, front calipers and pads and rubber brake lines. I have slight brake when in reverse but no brakes moving forward. When bleeding brakes get slight pressure but as soon as the car is off pressure goes away. Have bled the system about four times and still nothing.

This is because you have air inside the ABS controller, you must connect a scanner and open the valves as you bleed the system. Here is a video on how to do the job. You can get a scanner on amazon for about $150.00.
