Welcome:

The first and easiest question to ask is are you sure it is fully bleed, they can be a real bogger to do. Especially, if the Master and Slave are new.

Is the flexible pipe ok? If the cloth covering is broken it can swell on pushing the pedal and then the clutch doesn't disengage and the pedal feels soft.

My money says that there's still air in the system.

Bleed the master cylinder first: to do this properly, take an old section of your steel tube, and cut/bend it so that from the output port, it goes into the reservoir below the fluid level.

Slowly stroke it a few times to expell all the remaining air.

Reconnect the new steel pipe down to the slave cylinder and bleed accordingly.

This should solve your problem.

Whenever a master cylinder is being replaced, always try to bleed it on the bench before trying to bleed the whole system, and your life will be a little bit easier :wink:
