Hi all, further to the past posts (54785, 55142) on the brake failure of my boss's new GU.
After replacing the entire braking and ABS system (didn't fix it) they realised that there is a small thinghy in the back of the brake booster that is dumping the boost as you put on the brakes in a hurry. It is letting enough boost thru for the front right wheel to lock up then it dumps the boost stopping the other 3 wheels from braking. keep in mind this happens in a fraction of a second.

They have changed the part so we will see if it was truely the cause.

Hmmm... It appears to me that something in the brake booster itself would be common to all 4 wheels, not just one front brake. Will be interesting to see if Nissan have fixed it.
