Yes. You need to disconnect the tubes coming from it and fabricate temporary tubes that circle back into the reservoir.

You may be very surprised to find that is the source of the air in the system.

It's ok to disconnect those temporaries and re-connect the permanent supply tubes. The air you are introducing to the system is outside of the master but you will need to rebleed the front and rears to get that little amount you just let in completely out.

If the pedal doesn't get high and hard then the master has a leak in one of the o-rings and needs to be replaced.
