Thread: Left Foot Braking = Hesitation?

I used to left foot brake all the time both to balance the car and to stop, then I
bought a GT diesel Golf which didn't allow such behavior, after three years I got a D3 and now a D4.
I remember being mightily displeased with the Golf. I didn't even realise the Landrover didn't allow it either.
Until I read this post I had forgotten that it used to be the norm for me.

It may not be failing - just adjusted incorrectly.

If all is working correctly, transition braking isn't considered necessary in a D4, as the DSC and ABS should correct any abnormal trajectories. On the RRS, you could have the Dynamic Handling option which goes further with this approach.

Not saying it's any better than an advanced driver, but that's how the systems have been designed. It's not a Lotus

Cheers,

Gordon

This could explain why you see this effect. However I frequently "drive through the brakes" when offroad, so suspect it is speed sensitive, or terrain response sensitive.

With my Touareg I can load it up while foot on brake, and put on throttle which gives it mighty quick getup and go, but if I was cruising along with foot on throttle then hit the brake pedal it will cut engine power.

I can do exactly the same with my D4.

But when I am reversing the D4 I can have foot on the brake while using the throttle....which is also the same with my Touareg.

I guess that's the way it is.

Could also be part of the problem I mentioned in you other thread. Often coming into a roundabout, especially down a hill close to home, I'd brake, check to see if it's clear, the accelerate away. Quite a few times nothing happens, so much so that once a Pajero entering, after me, felt like it was about to rear end me. Then the power came on, and I was away. Real scary. So far haven't seen that with the update. But with brake pedal, could also be a fuel economy measure, having seen many people ride their brakes driving around.

Sounds like hill start assist technology to me, encountered it in another European vehicle.

Its there because cars are designed for the lowest common denominator in drivers, and some people cannot coordinate the handbrake and accelerator to complete a hill start.

So, when you take your foot off the brake the electronics hold hydraulic pressure long enough for your foot to apply throttle pressure.

You'll have to stop driving the D4 as if its a kart!

The brake switch in my D4 failed at 11,000km.

I now carry a spare all the time.

Mine failed around 80,000km and was fixed under warranty. I also now carry a spare with me. There is no hesitation now but there was significant hestitation after slowing using the brakes for many months before the final failure.

My LR3 and now 2011 RRS both do it.
Until I understood what was going on it was quite disconcerting.
I thought that I had an engine issue initially.
