Hi, can't remember which thread questioned this issue but Mark at Mclaren London worked it out.

When the car comes to a stop, presumably in the pits ( it's academic in the gravel),with the engine running, , PUSH THE Neutral button and then the engine on/off button. The handbrake remain off.

Won't the car move? I wouldn't want to leave the car in neutral without brake. Anyway to keep the gear engaged?

Well I'm not sure as double clutch boxes have clutch lag.......erm........I will have to see what happens on my sloping driveway. Maybe MSO will produce a Track Day Wheel Wedge!

My guess it will move/freewheel.

Bargain by MSO standards?

Been there, tried that,

And then you open your door and the handbrake comes on again. Sometimes even only after a few minutes, it is something strange, but nervewrecking when you don't like your brakepads sticking to the rotors.
I really couldn't let my guard down while trying to get the tyre temp down, and they really needed cooling at Paul Ricard.

I think every new car with automatic handbrakes has the same problem.

You would think Christ Goodwin knows a solution?

Maybe they could program the handbrake to act differently when the car is in Track Mode?

Probably there is a greater concern of the car rolling into something unintentionally than there is not having the hand brake pad fuse itself to the rotor when super hot.

just thinking out loud, could you close door with window down, and then reach in and disengage the handbrake?

Ok, cracked it. I have to admit I'm a MP12 Anorak!

I knew Ron, who has car racing DNA, would have thought it through.

Page 61 of 223 of the manual that all owners have read twice.

Quote. If the parking brake is not applied manually it will apply automatically when the engine is not running and the driving door is open. Automatic operation can be overridden by holding the parking brake switch in the down position whilst opening the driver door.Quote end

You could interpret that this has to be done with the engine running so we need to try it with and without the engine running.

Well done Ron, I know you follow the forum.

If the engine is running the parking brake will not apply when opening the door. But i think when you kill the motor it will engage again.
If you want to reach in to disengage it once its set you will have to push the foot brake again. hard to do with the door shut :)

Ok - here's how you do it - I did it at the track yesterday.

When you stop the car and open the door, the brake will come on.

With the door open and car off (and PB on) - with your foot OFF the brake, hit the start button until the TACH comes alive, then with your foot ON the brake, turn off the parking brake. Take your foot off the brake and turn off the car. Your car is now stopped, door open, parking brake off.

Note, when you re-open the door after this, the brake will automatically come on.

Hyper,

Thats what i was trying to get at. If you do this with the door already open, the parking brake will not re-engage, but the car will roll so be careful.
I do this after hard driving as I'm concerned about the PB warping the very hot disc's. Used to happen on the Ferrari's and i learned the hard (read expensive :eek:) way

The problem is that the car is in neutral and will roll away! The question is how do you keep the car in gear with PB off. I asked my salesman yesterday, and he did not have an answer. He'll get back to me.

You cant leave it in gear !. Plus without the engine running, i don't know if the hydraulic clutch is engaged or disengaged. Either way Peletons $12 solution is best :)
