No brakes, aghh, :/

Very confused :/

i was driving down A47 and brakes locked on on my series 3 200tdi, 1978 non servo, and heavily overheated warped drums and generally a mess,

Anyway just been fiddeling and it had melted the seals in the wheel cylinders, *only 3 months old* so i have fitted new wheel cylinder seals from overhaul kit, new brake pads and drums, and a new master cylinder as i think the master cylinder failed and wouldnt let any fluid back through, so anyway ive fitted a new delphi what ever brake master cylinder.

But i just cant get any pressure in the system, no matter how much i bleed it. im getting fluid all over through the sytem no bubbles, :/ not even abit white fluid from having small bubbles in it. i bleed and i bleed with no air coming out of bleed nipples. the peddel isnt even pressuring up no matter how much you pump it. any ideas :/ ive gone over all the pipes on the master cylinder for leaks and isnt any :/, im confused and wheel cylinders arnt leaking fluid.

help please
