Can a bad right-rear wheel cylinder lead to a destroyed rear-wheel HUB assembly on 1994 Dodge Grand Caravan

Had my '94 Dodge Caravan SE 3.3L V6 right-rear wheel cylinder reviewed & after leaving mechanic shop (10-15 mins) later my entire HUB was dismantled while driving. Wheel tilted to one side. Towed car to shop for repair. Curious to know whether the individual made a costly mistake when re-mounting my wheel or is it known that a bad cylinder could lead to a bad HUB? No prior noise or vibration until the DRUM was removed to view leakage from the cylinder. Please advise. Thank you for your assistance.

Absolute mechanic error. No question at all. Your wheel cylinder is not even relevant to the hub and mounting. Good luck - hopefully they will step up and handle the issue.
