Unfortunately anything mechanical can break. Tesla’s calipers are from Brembo - about as good as they get.
Given that you’re in NJ (like me!) — we really should clean and lubricate the calipers annually. The road salt and grime in the winter needs to be cleaned away.
Also since you’re in Vorhees - have you heard of the Delaware Valley Tesla Owners’ Club (www.DVTO.club)? We have some great workshops that review things like this. Come join us!
