Scary Sudden Wheel Lock Problem

Rear left wheel suddenly locked. What could cause that? Has anyone else had the same problem?

loose brake items,but more likely axle bearing siezed.

It can be a mechanical issue.

I have seen the hydraulic proportioning valve stick and fail to allow the wheel to release.

There is no big issue to geting it fixed before it causes the car to leave the road. Fixing the damage afterwards can be very expensive.
