    Park Brake Behavior ?

    My own S type is the only one I have driven. My park brake holds no problem BUT it will not apply if you are on the move say above 5 mph Pulling the park brake on the move does not illuminate the red p brake. Is this normal ? My drive has a slight slope & if I leave it run back in neutral Park brake works fine.
    I ask as I saw a couple of vids on youtube where they were trying to do hand brake turns using electric park brake cars at high speed & all the late model cars (not jags) tested did attempet to apply the brakes but not always locking the wheels.

    So is the Park Brake inhibted from being applied above a certain speed?

    "All vehicles: Inadvertent operation of the parkbrake whilst the vehicle is in motion will cause the message ‘PARKBRAKE ON’ to be displayed on the message centre, the warning light in the instrument cluster will be illuminated and a warning chime will sound.

    If the parkbrake is applied whilst the vehicle is moving, releasing the switch will disengage the parkbrake. The parkbrake cannot be applied whilst the vehicle is moving and the throttle pressed.

    Note: If the vehicle is in motion, the parkbrake should only be used as an emergency brake.

    The parkbrake is automatically applied when the key is removed from the ignition switch. If you wish to keep the parkbrake off, press and hold the parkbrake switch down and, at the same time, remove the key"


    Maybe that is where you are going wrong? It should apply while moving though.

    what about holding the switch up?

    Certainly landrovers are intersting pulling the park brake. It does a very quick emergency stop! Even uses the front brakes too I believe

    As far as I know the park brake will not apply when the car is moving unless it is in neutral and with no pressure on the throttle.
    You then have to hold the switch up to keep it on and there is a delay when it is applied.
    If still moving after the park brake is on if the car is put into drive, reverse, the throttle is pressed or the switch allowed to go down to its normal position the park brake will release.
    I have never tried this and I can see no reason for trying it.
    It should be noted that this is just a parking brake, it is intended to hold the car in place when it is stationary. It is not intended to stop the car when it is already moving, that is what the foot brake is for!


    There was a time when the hand brakes on cars was classed as the 'secondary brake' but these days all the car braking systems have at least two hydraulic circuits that satisfy this requirement. The hand brake is now just a parking brake. The parking brake only needs a 16% efficiency when both sides are added together, but both sides must work to some extent. A locked wheel is 100% efficient, the 16 % depends on the weight of the car.

    To get the park (emergency) brake to apply when you are moving do the following.
    Take foot off accelerator
    pull up switch,
    the longer you hold it up (or multiple applications) the more the brake applies.
    let go of the switch and what ever brake application is applied will remain.
    to release the brake either press the accelerator or push the switch down.

    Doing this will illuminate the Park Brake light along with warning beeps, beeps stop when car comes to full stop.

    Ok not tried to apply the park brake on the move AFTER shifting to neutral.Will try when next out in the car.

    I assume my park brake switch works ok. Is it normal for the switch to be weighted to the down or off position? Ie it has to be held in the up position it does not click like a wall light switch If I apply it at traffic lights & I can see the park brake illuminated in red When I move off in drive I can here the park brake release.
    As I say I never gave it any thought that it is supposed to work as would a cable handbrake at any speed within reason.
