Sounds like air in system. Look for leaks or if something has been changed recently....it hasn't been blead properly.

This will usually result in same 'nothingness' everytime you push the pedal.
If he is having to 'pump' the pedal to improve it, usually that's air in the system.

Sounds very much like air in the system. Has someone allowed the system to empty? There may be air in the abs pump, which will require you to find a loose gravel surface and make the ABS work to release the air, so that it can be bled out.

It's air. Blead the system properly!
It won't be rear adjustment if pumping it fixes it

No.
only the master can be made to fit, nothing else is worth the hassle.
