Brake pedal to floor

I was getting a whining noise from front so I changed the wheel bearings. Please note the bearings I purchased are for ABS brake system and I don't have ABS brakes, however when I spoke with a local friend he stated that as long as the bolt pattern was the same there should be no problem with using them as I already had the others off the vehicle when before I noticed they were different. Everything bolted up fine and I test drove the vehicle and all seemed well. Until my wife drove the vehicle and noticed a bad vibration when braking and it would not got away. Then it would, then it would come back. I assumed the problem was a sticking caliper or failing brake line. So I purchased both and replaced both lines and calipers on the front of the vehicle.. After completion I went to bleed the brake lines and the brake pedal went to the floor especially when the vehicle was started. Bled the brakes lines 2-3 more times and never could get pressure at the pedal. I then purchased and put on a new master cylinder and bled the brake lines 2-3 more times. I still have no pressure the the brake pedal. Getting very frustrated.
