The download etc is free - best deal you will get on the Forum tonight anyway. Yes, there is a parking brake procedure; sounds like some are learning about it the expensive way. All is explained in the download.

Bodsy keeps updating it as he tunes the 36 page pdf up.
The best part is probably towards the end, (page 27/36 and onwards), re the electronic parking brake.
It is black art stuff, (well leading edge, maybe bleeding); also the set and unset procedure applies when doing just a normal rear pad change.
If you ignore the set unset procedure, then a few miles down the road, the squealing will start.
The fronts are more normal, but the rears, not!
You actually have three pair of brake assemblies to deal with: (1), the front pair of rotors, and pads, (2), the rear pair of rotors and pads, and then (3), the parking brake pair of drums and shoes – yes, drums and shoes.
That is why you can use the parking brake as a “dynamic” system to safely slow the vehicle from highway speeds. The owner’s handbook explains the procedure as below.
Dynamic operation: In an emergency, the park brake can be applied dynamically’, i.e. with the vehicle travelling at more than 3 km/h (2 mph). Pulling up on the lever and holding it up gives a gradual reduction in speed. The brake warning indicator will illuminate accompanied by a harsh sound and a ’Caution! Parkbrake applied’ appears on the message screen. The stop lamps will illuminate. Releasing or depressing the lever will cancel the parkbrake application.
