soft brakes with full travel

I am new to brake repairs so a friend of mine replaced the front right (passenger side) caliper,both front brake lines that meet the calipers,both rear brake cylinders,both rear brake lines and rear shoes.
After all that work he bled the brakes my going to both front caliper bleeder screws (new ones) and the new rear brake cylinders one by one while while I pressed on the brake pedal 4 times and hodling it on the forth but the brake pedal is still soft with full travel and while driving very little brakes.What is the proper way to bleed the brakes?also now when braking the vehicle shakes I never had that problem before,could tapping on both calipers with a hammer caused something to go wrong on the rotors?.
Thanks in advance for help & replies.
