Not so sure about low pressure doing that.........depends how low, 'low' is I guess.
No pressure on the other hand. Unless you spot the deflated one on the walk round, and believe me you could easily miss it- even if you kick it, NO pressure will cause no torque to be passed into the brake pack. The brake normally converts the torque into heat, so no torque- no heat.
If you land and one brake temp stays very low- you've got a flat.
