OK taken that you know the basic principle and have generally done everything right, and no fluid is leaking from any seal/banjos etc.

could be one of three things,

first a trapped air bubble in the caliper, try whilest bleeding it just tapping it with a spanner, you may find this dislodges it and you get a small bubble or two come out ?

second, the air bubble is trapped in the master cyclinder, bleed the top banjo (don't forget to use a rag under it) and then with the top of the res removed pump the lever a few times (with the rest of the system closed) and watch for a few bubbles coming back up into the res.

Three, when doing the second (above) if fluid is pushed back up it'll indicate the master cylinder needs sorting.

you could also try hanging the calipers above the master cylinder and bleeding that way as it tends to be easier to get all the air out.

Cheers Mark.
