Tested everything.
Deleted bias valve
Swapped hoses over tried old rubber hose too
Swapped calipers over both okay
Bled with calipers up top
Fitted another master and servo ( cheers jordi)
Clamped off rear feed flexi hose from wing to chassis front brakes working fine good solid pedal
Blanked off one side of axle t piece . Drivers rear good solid pedal
Blank other side of t piece and Try with Rear passenger and it just lets pedal to the floor
So im left with the t peice or copper pipe being at fault which makes no sense.
will try again tomorrow. Im heading home
