Your problem is the air is trapped inside the calliper somewhere and needs someway of coming out. See my post above for some ideas.

i'm not trying to be funny here, but the master cylinder plunger hasent 'stuck in' has it?

you have closed both nipples when you are trying the brakes?

even with some air in the system you should still feel some resistance at the leaver.

Are the pistons in the calipers out from the caliper? If so, remove the caliper form the fork and press the pistons back into the caliper (Both at the same time) (make sure that the resiviour is not full when you do this. This will push the fluid back up the lines and hopefully air.

Just while i think of it, all the banjos are tight and you do have a copper washer on both faces of the banjos at the top and bottom?

As for the fluid out of the nipple, this is ok, but you really only need to open the nipples about 1/4 of a turn. If you where closer, id come and do it for you. It took me forever to get the knack but now i have, i can do it with less than 250ml of fluid!

thats the winner i pushed the calipers back and after 4 or 5 pulss on the lever i had pressure

lever is a lot firmer now, no bubbles coming through the nipples as far as i can see so ive left it cable tied for the night

many thanks .org

YeeeeeeeeeHaaaaaaaaa , we have a winner

I just odered some HEL lines too. For £58 I couldnt see a reason not to!

Whats the best way to stop air from staying in the callipers, maybe fill the callipers before you attach the lines?
