im in Disney and he tea cup were down 2 days ago for a 1 day refurb. Speaking to the cast members it was to work on the breaking system. It's open now and it seems to be breaking a lot quieter. It's not completely gone but when I talked to a cast member he said he was under them today. There is a new break rubber mechanism and it rubs against the metal to stop it. It was replaced but since the humidity in Florida it causes the rubber to sweat and that makes the little squeak. It is however much better at this time.
