Parking Brake Performance.

For the same reason that there's not an advisory for limited reserve travel on parking brake control. Not sure what the reason is but I couldn't share my thoughts on it politely

It would still be a good idea to have the advisory for only just achieved minimum park brake efficiency. As for excess movement of the lever, that definitely needs to be reworded. 'Indicating incorrect adjustment' is a diagnosis we are unable to make during an MOT inspection. It is also only one of several possible conclusions. It ought to be removed at the earliest opportunity.

At the wheel or Reserve lever travel?

The parking brake on a Quad is the service brake lever being locked in the applied position so technically it's the service brake

    That is what i do but seems so easy just to add an advisory to this section.

I would question that comment. Quads still require a seperate mechanical means of applying parking system, usually via a transmission lock or a seperate lever & cable mechanism to act through the brake caliper in the same way as a conventional car type set up. Your description is effectively a hydraulic parking brake arrangement, which is not acceptable.

    I have done that in the past as well.

No, all fully road legal. Some of the Auto's have Park and also the Lever Lock system.

No Quads have a designated Parking brake system. It's either Locking the left lever which is for the rear service brake, and some the right lever locks the front and or the Park Position.

Park isn't any good when you are crawling up a 30 degree slope, lever lock is.

Most have both unless they're a Manual transmission.

Edited to add: no Quads I've seen or used
