Complete right side brake failure upon landing in ZZZ.  Brake line became detached. Failure of some sort after brakes had just been replaced on #3 and #4. Surprised that entire right side brakes failed.  One brake line detaching should not have resulted in complete right side failure.
Air Carrier Flight Crew reported brake failure on landing.
