Brakes acting wierd(searched)

[PomiDori]

Setup
ABS deleted
300zx master cylinder new
300zx front and rear calipers bleeders on top of the calipers
ebc yellow pads
Blackworks(Exactly the same as Ksport)Ebrake
auto brake booster

When the car is not running pedal and Ebrake is stiff,once u start driving and push the brake pedal it goes all the way to the floor and no stopping power,but if u pump brake pedal twice it works perfect.Ebrake is stiff, but nolocking

The way I bleed the system is pump brake pedal 2-3time till stiff open the bleeder push the pedal down then Ebrake,closed the bleeder.There was no bubles.
Help!

get yourself one of these much much more easier to bleed. did you you bleed the rear calipers first then move to the fronts

Bought vacuum kit like that and bench bleed kit,bleed it no air in master and no air in calipers and still no change.
I will try to adjust the stud on the brake booster.

yeah same problem here . i used 1 of those bleeder pumps and no air in the system and still no change?? same problem like this guy. you think it can be the master cylinder????

Update figured that bleeders in the rear was wrong size(some standart size),but they never leak.
bought some 10m1.0 bleeders gonna try tomorrow.

So you are saying if you have the car off and pump the brakes its hard? Then, if you hold the brakes down while turning the car on it falls to the floor?

no stays hard.

When does it fall to the floor?

[PomiDori]

Once u drive the car it goes to the floor.I know it sound like bad brake booster,but
I checked master cylinder and brake booster according to FSM.

update

there is a rod with nut under the dash by the brake pedal,so the nut was loose and the rod it was spinning freely. rod adjusted,nut tight-problem fixed!
