Thread: Left Foot Braking = Hesitation?

I suspect it is programmed in to prevent left foot braking from loading up the torque convertor / transmission.

could also be a crash prevention technique,

i.e. jamming your foot on the brake and half on the accelerator in an emergency by accident, therefore it cuts the accelerator.

maybe

Long story as to 'why'... but I'm relieved to see another driving technique heretic ! I find it safer in traffic - shorter reaction time and more control when reversing.

My Classic's 4 spd ZF does'nt do any of the above, so I'd guess its a function of the engine/gearbox management systems, such as the programming engineers never forseeing such sacrilege. But then again, mine's a technological dinosaur compared to D3/4....

Or a glitch...

I understand that (probably wrong) when you press the brake, the CAN bus tells the ECU to ignore all accelerator input...at least that is what happens with my diesel VW.

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.

It is a characteristic of the car - designed to act that way.

LR's philosophy is that the electro/mechanical aids in the vehicle do not require the use of simultaneous braking and acceleration whilst off-roading. There is no requirement to "overload" the diffs due to the TC/TR, and HDC/DSC takes care of the rest.

Mine's a 2012 D4 six speed and I haven't seen this "delay" at all. I don't normally use left foot braking, but have done occasionally in tight parking / manoeuvring situations, and have also been known to occasionally sit at the lights with left foot on the brake and right foot with slight pressure on the go pedal for quick get-away. Have never noticed any delay or similar issues when doing this.

It's actually the correct way to drive and something that is not taught to the masses, yet funnily enough is in hi performance and skid pan driving techniques. Application of the brake can shift weight transfer, steady a car, balance before braking, or provide a gradual weight shift rather than sudden when undertaken correctly, even whilst accelertaing. It actually becomes a habit.
I actually left foot brake in a manual, except for when coming to a stop.

Much safer in traffic, cuts reaction time by over 50%, I find it very useful in carparks, and when in busy intersections and you need to react quickly. trying to reverse the car last week with a tonne of wood in the back up a hill proved quite difficult as I had to balance the cars movement on the accelerator whilst in a tight position.

Thanks Gordon, makes sense then from a 4wd perspective however on road even the slight brush of the brake at the wrong time Proves to be quite dangerous. I have actually done it by accident and have been left stranded in the middle of the intersection. I am not “loading” the brake and accelerator at the same time, actually it’s a smooth transition between the two, the cross over in most circumstances is nil, however the movement between two pedals seems to need a particular amount of gap between the two (approx 1 sec)
