No brakes after body lift

Hi I have just body lifted my disco 2 and the brake pedal has gone solid all the brake lines have been replaced and the system has been bled up multiple times I've had a look round n can't seem to see any obvious faults or even a load sensing valve on the rear axle, it is possible to stop the vehicle if you put your whole body weight on the pedal, had anyone experienced this problem and how was it rectifyed?

Thanks
Ted

Always worth posting in the introduce yourself section, saves upsetting the natives that way

As for your brakes, did you remember to connect servo vac hose?
Sounds daft, but are you running engine as you press the brake pedal?

Hi, yes I've checked and double checked everything surrounding the servo and yes I'm running the engine, whilst bleeding the pedal felt absolutely spot on but as soon as the bleed nipple was tightened they went solid
