Undo the bleed nipple release nut and attach a tube and pump the brake to squeeze the fluid out, and as it goes down in the reserve just top it up again and repeat until the air is gone, my understanding of it that a few times of doing this will work a treat. Leave the top off the reserve as you do it so you can fill up and any air stuck in the pipes has more freedom to bubble up.

Thats how mine worked anyway, I'm telling you this whilst deleriously tired so excuse any mishaps with info given.

As you pump the brake with the top off the reserve and the nipple open it will allow the lodged air to be forced downwards. This action means eventually it will be the airs turn to be forced out of the nipple. Thats the working behind it anyway.

also when you have no more bubbles coming out of the bleed nipple, tighten it and tie the brake lever to the bar and have a cup of tea / diet coke etc, then undo and pump the brake lever, this should firm it up, was skeptical, but worked for me..

and remember, you first few brakes wont be as good whilst the pistons set them selves, so dont try any 60mph stoppies..
