Thread: D4 3.0 SDV6 catastrophic failure

Re electric handbrake.
The reason everyone is going to them is that they become a true emergency brake.
If the driver has a heart attack, or similar, the passenger can press the button and the car will operate the ABS in a controlled emergency stop and then put on the park brake when fully stopped.
That's good to know when you get to my age!

And so goes the old joke : "I'd like to die peacefully in my sleep like grandpa, not screaming in terror like the other occupants of his car".

I've given this a lot of thought, particularly after discovering >50ml of oil in my brake booster. I'm comforted that in the event of a catastrophic brake failure, down hill with the van on the back I can pull the lever and the car will do it's damnedest to get us to stop. Every other vehicle I've owned has a handle that operates small drums on the rear axle, and they have a hard enough time slowing the car in an emergency, let alone with an extra load.

Yes, the emergency max application of ABS braking with the handbrake button works very well, but I’d not thought about how it would work better than the foot application, but on reflection, if the booster fails, it definitely would. Nice to remember

I've used the handbrake button in a controlled environment, on gravel no less, during a GOE training session. Pulled the car up from 80km/hr pretty damn quick, whilst keeping it in a straight line (ie, stability control is used). Whilst it wasn't tested, it will also actuate trailer brakes i'm told. All in all I was pretty impressed.

Makes sense as I was testing out HDC and whether it applied the brakes and it did, hence it applied the trailer brakes, therefore ABS would too

OMG, just realised we've strayed miles (or should it be klms?) from the original post.... I'm surprised that someone is not complaining!

Apologies to future forum readers who just want to know more about the engine failure!

Even more useful if the master cylinder was to fail.
