Re: Electronic handbrake stuck on during MOT and won't release
Personally I'd have a go at the garage.... if front wheels turn when handbrake is on, the handbrake applies more power to stop the car rolling.
And it sounds like it's managed to jam itself up.
I'd suspect either mechanical jam or electonics inside the unit burnt out.
Take a looksee in the stickies, there are a couple of threads with strip down photos.
The emergency release is a mechanical release that lets a pawl in the unit release the cables.
If there is a mechanical jam, it may not release both sides as it relies on tension to operate... pulling it when the handbrake is off does nothing for example.
I think that you are going to have to drop the box from under the back axle and open it...torx screws on the one side after you remove the carrier. That will give you chance to have a look.
