    if yes ...
    How do you do that?
    And how do you re-engage them?

    All I want to do is rotate the rear wheels, with the car turned off, to clean the rear Reluctor Rings.

    So no Parking Brake and No P Pawl engaged. I.e. in Neutral.

    If you turn my car off, with her in N, as you open the door it thoughtfully slots it into P, and the brakes are applied.

    The MBII has a pre menu, that says
    “Brake Reset” ... does that lead to a sub menu?

    I didn't want to just “try it” incase te MBII cant do this on my car, or it locks them on or off permenantly.

    Note I do not have SBC.

    Leave the key on position 2 and it won't do it.

    Thanks,
    I remember reading somewhere its not good to leave the Ign. Switch On for long.
    I assume that doesnt apply to modern cars.

    WIS says to turn the ign. Off to remove the Wheel Speed Sensor.
    I assume it cant do any harm other than throw a fault code while the ign. Is on.?

    Well, I wouldn't leave it on for long, you will flatten in battery 50% In approx 30 minutes

    Any takers, from MBII users; as it would be useful to know
    And helpful for longer jobs like changing rear discs, etc.?

    It also took me about an hour per reluctor ring, as I cleaned the wheel inside and wheel arch etc.

    I thought I saw it written somewhere it did this. Guess owners with SBC would need it even for front pads.
    But as you know there is no manual.

    SBC can be disabled, then star disconnected and it will remain disabled.

    EBC cannot be uwound then stay unwound without star active and key on.

    Im pretty sure you can put it in neutral, leave the handbrake off and then turn key to off with the door open, it wont automatically engage.

    There’s a manual release in the fuel filler flap , you screw a rod into the hole and pull it to release, rod is part of the tool kit! Sure it’s the 221 /216 which has this??

    No problem taking out the rear pads, other than one couldnt rotate the disc to clean it on the reverse side due to the plate shield. I assumed one would have to release the parking brake to remove it and then get the disc off, but not sure.

    Worth buying that rod part Cole mentioned.

    Thanks
    You are brilliant.
    Well hopefully I got the right one. £6.34. :)
    The MD parts department say there is a threaded T handle bar, called “Unlocking Parking Brake Handle” .
    Parts had never seen one ... but he did say on EPC the EPB Unit has 2 cables, one to each hub, and a 3rd long wire going “nowhere”.
    Obviously to the filler cap area.?

    Apparrently its part of the original tool kit.
    Could be useful :):)
    Its ordered.
