‘Auto park brake’ should be on, click it so it shows ‘off’.
Next is to click on ‘Brake service’.
On this page click ‘yes’.
It should then say ‘Parking brake retracted’, there’s nothing more to do on the menu until you have replaced the brake parts.

To keep the calliper out of the way you can secure to the rear spring (we used a cable tie).

Give the brake disc a little tap to loosen any corrosion holding it to the hub.

At points of contact (where the brake pads touch) on the calliper and carrier dab some VR 500 (stops the pads from sticking) or something similar then reassemble using the new components.
Go back to the menu display, to reset, press the brake pedal…
….and activate Park Brake switch.
Pump the brake pedal (it should firm on decline) and test the brakes at a low speed.
