Detachment of the disc hat from the braking surface

Mechanical stress through misalignment. Incorrect assembly or positioning of the caliper and disc results in ongoing asymmetrical wear of the braking surface, eventually causing detachment

Initially loud noise and vibration during braking with complete mechanical failure after detachment

Full inspection of braking system and associated components. Replace any failed components and fit new discs observing manufacturer's recommended torque and sequence during tightening. Before ftting discs check the alignment and assembly of the caliper body on the axle
