Discovery brake bleeding query

Hi there

I have a 97 Discovery V8 ES with ABS brakes I've flushed the system and my brakes at the back have been bled easly enough but the front ones just seems like there is air in the system and I'm not getting a solid flow of fluid out of the nipples.
I've been at it for while now and think may be there is something wrong some where else down the line.The peddle goes to the floor easly when the system is closed of and doesn't seem to rise the more you pump it like you expect it to.There are no leaks.
If anyone could shed some light on this problem that i have, that would great.I hope all this makes sense also.

Thanks in advance Ben.

try bleeding master cylinder at rear pipe ,open then press pedal down then close before letting pedal up repeat till no air ,could easy be faulty master cylinder though does it splash in reservoir when pedal pumped is there a black deposit in bottom of res

There is no black deposit that can see but yes it does splash a little in the resivoir I first noticed that when there was a fluid all over the servo.When you say bleed rear pipe do you mean on the master cylinder it self?
Thanks again for the speedy reply.

yes at master cylinder ,its 2 pumps in one rear pipe does front brakes front rear brakes ,seals can go for either

Ok cheers for that I will give it a try and let you know how I get on.
