Auto Hold Brakes (which brakes are applied?)

[Royalstorm]

Hey. Anyone know what brake (or brakes) are employed when auto-hold is initiated?

I think it is all four like you would normally press the brake, it's not the same as the parking brake. You can actually hear when the parking brake is applied.

Ok. Thanks. I have a vibration hum (that I posted about previously) that occurs when the brake pedal is slowly released after a complete stop but also is present when auto-hold disengages. I’m trying to figure out where it is originating and was hoping it was just the parking brake, as that would make it easier to localize the problem.

The brakes from each wheel are applied.

Dealership used the chassis-ears and after replicating the sound, they localized it to the exhaust. So now they are going to wait to hear back from Kia about what fix, if any is recommended.
