R34/laurel/brake Booster And Cylinders

[30detkiwi]

so this is the deal

I have a c33 diesel laurel..

i have r34.5gtt front rotors and calipers.r34 booster,master cylinder.

i have the factory single diaphragm and master,but i have disconnected the rear lines & made a hydraulic handbreak,using the line from the master cylinder to the rear junction box,i coiled it up and connected it to my hand reak master cylinder,bleed it up and it seems to be doing its job.

now on my factory laurel master cylinder i welded up the valve that was running to the rear breaks(marked with a R),and reconected the 2 remaing lines that go to the r34 break i have fitted.

NOW iv tryed bleeding the breaks from ps of car,then ds of car & the presser goes down and then returns back

i have also put the r34 booster and master into the car and it only got 2 valves on side of it and a screw on the opposing side.

iv had them booth out because they booth do the same thing.......

I am pulling my hair out trying to sort it..........

any info will help.

also does any 1 no what the hex nut that screws into the factory laurel does
