well you said you have no motor yet on the car. you have to turn on the engine to get vacuum for the brake booster in order to bleed the brakes.

you might have a clog in the hydro ebrake then. if not then try lifting up the handle up and down like you are bleeding it see if that helps.

is your hydro ebrake used or new. try checking to see if there is anything clog in it. o and try to pulling the ebrake up and down and see if the fluid pushing back to the master cylinder if it does then you got it backwards.

well you setup is different then my buddies setup. im not sure how the cylinder in the ebrake system is set up. try to swap the lines around and pump it to see were the fluid is coming out of. as for the master cylinder it seems fine cause i got my set up the same way, but with a usdm 300z brake master cylinder, but with no hydro ebrake.

Ok guys I figured it out... The diagram I have is the correct way to install it. THe problem I had was the fitting that goes into the cnc piece... Not the brake line but the little gold fitting... For one it was damage and 2nd it was on to tight... There is a little hole in the back port and when tighten to tight tHe gold fitting covered it... So once again it is the correct way to install the hydro e brake
