If you use a pressure bleed system make sure you decrease the pressure in your air supply.
So where does this bit go then ?

Update
So I couldn't be bothered anymore so booked an MOT and took it in. The brakes probably worked as well as they have since I bought the van so was just trying my luck. The MOT tester got in the van pressed the brakes and immediately told me there is air in the brake lines. He checked everything else I had done and said its all fine apart from the air in the brake lines.
I took the van across to the garage and booked it in to have the brakes bleed the next morning (they charged me £40). Left it an hour and a half. They phoned me and said its all done and passed the MOT. When I go there to pick it up the MOT tester said the garage still couldn't get all of the air out and the brake pedal is still spongy but better than it was and he passed it.
On reflection I don't feel so stupid now as I've bleed brakes before with no problems like this. But air has to be getting in some how right? If a garage with all there equipment cant do it and cant find a leak then whats going on?
I am also glad I didn't buy an easy bleed as I would probably still be pulling my hair out wondering why theres still air in the lines!
Anyway I'm back on the road and the brakes do work fine but still only as good as I got them really.
Thanks for all the help and advise guys.

I had major problems until I bought 1 of them cheapo pressure kits like above. These are by far the best imo and will push any trapped air out eventually. Wouldn't do it without one now. You'll need a tyre pressure reader or similar and be sure you get the pressure right as if it's too low it won't work and too high it could maybe do some damage. Probably not but best to be safe.
Also make sure you start at the right end of the car. I have forgotten if it's front or back but Google will tell you in no time. And buy plenty of fluid... 1st time I did it I ran out because I underestimated how much air had got trapped. 2 bottles should be fine but if I had problems I'd go for 3 in case.
Oh and like frosty berlingo
If I can do it, I anyone can do it.

Oops I posted that before I finished and it won't let me edit...
Like frostyberlingo says I'd have a look at the master brake cylinder as air likes to get trapped in these from my previous experience changing one. The pressure kit shout blow it out no problem but you may have to bleed it.
Good luck?
