Good morning,
Bleeding the system can be difficult.
Gravity bleed it first by leaving the bleeder open and waiting until all fluid comes out.
Then I remove the slave and manually push the rod back in as far as it will go. Do this with the bleeder closed. Do this several times. Then install the slave and test for a pedal.
If you do not have a pedal at that time, yes, it could be the master has failed.
