First of all you need to tell everything in the first post.

Yeah based on what you say, that is how it is supposed to be. Have you tried adjusting the rear drum brakes? What kinf of car is this on? Does it have drums all the way around? If so, then adjust them all!

when your engine is off and you press the brake pedal repeatadly they will become "hard" lol... they will stay up they wont go down.. but when u turn the car on it will move with ease because of the vacumm to is connected from the engine to the brake booster

Did you bench bleed the master cylinder and bleed the brakes when you installed it?

X2. You gotta bench bleed it bro. Your Air BOund. Take it out and start over. You'll never pump the air out of it by bleeding the brakes. Thats just for the lines..

each wheel cylinder has a bleeder....have someone pump the brake a few times...hold it down..and open the bleeder till nothing but fluid comes out...repeat on the other 3 wheel cylinders..make sure u refill the master cylinder and check it after u bleed each one

The master cylinder needs to be bled alone without the booster. It also needs to be level. When it is on the car, it is usually at an angle. If it is at an angle, you may not be able to remove all the air from the fluid. :( Take the master cylinder out and bench bleed it. :biggrin:
