I've got 2ltr fronts and standard drums on the back. Basically its had new rear cylinders and rear brake pipes and my 2ltr setup off my old car fitted on the front.
When I did all that I drained the brake fluid off to replace with new, bled it up, no bubbles but a couple of inches of travel on the pedal. I didn't get chance to bleed it again before I took it to Castle Combe so I used that as a tester which showed that the brakes seemed to work as well as I remembered on my old car but you had to take up about 2 inches of travel before they started working whereas on my old car, you didn't.
Just tried bleeding them again now. I didn't drain it because the fluid in there has only done a few miles anyway. I put about 1/2 litre of fluid through each corner, saw maybe 3 or 4 tiny bubbles in all then I've just tried the pedal again and it's still terrible 
No sign of leaks anywhere.
Any ideas? 
Edit: Bled with an Eezibleed both times btw

Might sound silly, but I've found putting a bit of wood that pushes the pedal down over night may help.
Otherwise, Do you have the brake adjuster fitted on the rear beam? May be worth trying to move that.

You mean just keep the pedal held down overnight then in the morning it's ok or rebleed again in the morning?
By the brake adjuster do you mean the auto bias thing that works off suspension height? If so that seems free

Have you tried some hard braking?
Im sure you would already know this but when i use my brakes lightly, they have alot of travel like your describing. But after i have stamped on them a few times, they adjust themselves and there is hardly any travel in the pedal.

The pads weren't new, I had them on my old car, they didn't see any use between November and April though, not sure if that would be detrimental to them?
And yes, I did 2 15 minute track sessions at Castle Combe so they've undergone some quite harsh braking but no improvement.

Just looked at the pads on the side that Ian fitted and it looks like I'm due some new ones anyway so I'll get them sorted asap and see how we get on from there.
Thanks for the advice everyone

What are your brake lines like? The rubber bits i mean, if they're old they could be swelling up under pressure.
Replacing these on my xe, with v6 brakes, improved the pedal massively.

Did you have the correct air pressure when you used the Eeziebleed?
I think it needs to be 18psi.
I know it sounds stupid, but you did it in the correct order?

Yeah, I think it says between 15 and 20 psi, I thought 18 sounded nice so went with that 
And yes, furthest away to nearest.
