Rubbish.

So Wabco spent all this effort to overcome a non-existant problem ?

We all take our 4WD's to different places and over varying terrain. ABS is a potential killer in some situations and people should be aware of this. One of the advantages of this forum is that information is passed to others and this helps to make our 4WDing experience safer and more enjoyable.

It is aparent that you have not driven in these conditions. Whilst it may not be your thing to do so it is dangerous and misleading to infer that the issues/dangers involved don't exist or only occur if one is not 'driving sensibly'.

Someone's been thinking about this problem and offered a solution.
Now, to find out how well it works.

All-New Ford Ranger Raises the Bar on Safety | Ford Motor Company Newsroom

(New Ford) Ranger’s Anti-Lock Brake System (ABS) provides additional safety, especially with Gravel Road Logic that further improves stopping distances on loose surfaces, which are common in countries with a lot of unsealed roads.

If you say so.

The D2a manual has the following disclaimer relation to ABS:

It cannot reliably compensate for driver error or inexperience on difficult off-road surfaces.

I'm not suggesting anyone is inexperienced but it does seem to be a bit of a "get out of jail free" card for LR.

Abs is not required at all for vehicles driven sensibly, it's for when non sensible things happen

It may be fine for where you potter in the feelander or rr, how much off road have you done in those vehicles?

Quite a bit on the Freelander - more than enough in the RRS for the short period of time that I have owned it.

Yes if you race around at high speed relative to the road conditions on poor tyres you will have ABS chattering away non stop with extended braking distances. Most issues related to poor braking with ABS are not related to slower tracks but higher speed gravel roads here ABs can cause considerable extended braking distances if you are not aware of the issues.

Know the limitations and the advantages of ABS and drive to conditions.

They are my experiences - if others disagree - fine.:D

Hi,
Not sure if I have got this correct or not, but I believe that the traction control does not work in reverse.
We needed to have a vehicle do a 3 point turn on a snow covered steep road, and the driver was surprised that he had wheel spin and no TC light showing.
cheers

I must admit after having three LR vehicles with ABS and quite a few Jap vehicles also I found the poor handling of the Japanese vehicles played a bigger part in being dangerous than the ABS. Pat

I've attached a chart from the patent showing the progression from normal abs, to deep-cycle, to fully locked.

Attachment 46129

Once the wheel are fully locked they'll slide regardless of abs.

Sorry to reanimate this thread but I came across a bit of information that indicates LR did use the off-road ABS function. In a book titled the essential guide to choosing and using your 4wd vehicle published in 2004 by LR Australia, there is a section on Abs and 4wds which reads in part:

Even the experts disagree about whether ABS is an advantage or disadvantage off-road. For light off-roading, ABS can be helpful in keeping control of the vehicle, especially on slippery surfaces like sand, mud, or rain-swept tracks.

However in deep mud or gravel, locked wheels can actually stop more quickly, the debris forming a "braking wedge" in front of the locked wheels. For this reason, some manufacturers have developed smarter systems that can defect different types of road surface and change the cycle of brake pumping accordingly.

These "all-terrain" anti-lock brakes provide the best all-round performance -good stable braking on wet roads and short stopping distances on loose surfaces. Land Rover models feature "all-terrain" ABS.

You can definitely lock the brakes on the D2 at low speeds on slippery mud, and I'd suspect other LR models of the same era equipped with all terrain abs would behave in a similar manner.

The speeds for change over between the various braking modes can be varied by the manufacturer so they may differ from the speeds mentioned above.
