Update said it may have been hydraulics and the 90 passengers on board were deplaning onto the tarmac
Sounds like they deplaned at the gate, not tarmac.
Not sure why they would deplane on the tarmac, no one was in danger after they landed safely. If the brakes don't work then you tow the plane back to the gate with the pax onboard. Getting out slides and having pax disembark on the slides is risking more injuries.
