yes, thats what i thought was happening. there was a hook to keep the lever open, but there was way too many air bubbles fo what there could have possibly been in the system.

i i only just cracked the nipple open till some fluid came came out, then fitted the bleeder and done it slower by only pulling the lever a bit.

got about 6" of fluid with no bubbles from each nipple so i assume its near enough.

oh, one thing with 4 pots, which side of the calliper are you supposed to bleed first?

i done it with the furthest from the reservoir first, if you get me
