Parking brake rear assembly nut torque spec?

[Adub]

Hi All,

I posted this same question on the fiesta st FB group. But can’t figure out the torque spec of this nut (circled in red) in the rear parking brake assembly that was accidentally loosened. See image.

Does anyone know what the correct spec is by chance?

That's the rotational point of the parking brake assembly if I'm looking at this correct, so it needs to be able to pivot, right??? I'd say just tighten it down snug. I don't see it in the manual anywhere.
