One common misstep is connecting the hose to the upper port on the slave
cylinder and the bleeder to the bottom port. This will make it impossible to
expel the bubble of air above the bleeder. Some have gone to the extent of
dismounting the slave cylinder and holding it vertical with the bleeder port
at the highest point. This seems a bit extreme as I have had good luck
with the cylinder mounted with the bleeder above the hose connection.
Another possibility is that there is a fault in the master cylinder. There
is a small seal that closes off the port from the reservoir to the master
cylinder. There is a mechanism that pulls this seal off of the port when the
pedal is released. If the mechanism becomes disengaged the port will
remain sealed and it will not take up fluid when the pedal is released. But if
that was the case your wouldn't get the "trickle" you mentioned. (Never
heard of that technique before, how does that work?)
