PS
Dean Thats a very handy Video, thanks.

You're welcome . There's a few videos that we have done in that sort of style that you can see here if you, or anyone else gets super board . https://youtube.com/playlist?list=PL9yw83K...yP0bD4-1NU https://www.youtube.com/@scottandalana4x4

I have to agree with IanMetro…..à handy video Dean for the FL2 newbies / interested parties. item 1 about the electrics…having a good battery is very relevant……..I’m on my fourth…..
Item 5 about rear brakes….ok they wear out more quickly but if you compare pad sizes front/rear you can see why the rears wear more. Thé EPB equipped pads are a bit bigger but still way smaller.
Nothing to do with any stability aids……if the FL2 is solo( no heavy trailer) & on a good road surface you would have to drive like a loon to action thé EBD or other stability aids. In order to apply thé brakes involuntary thé ABS motor needs to be facilitated to provide fluid pressure. As you will know with off-roading thé ABS motor makes a fair bit of noise…….my point being you will know when it’s operating, & it won’t be during any normal road journey. If you drive like BossBob, Lightwater & myself….i.e. sensibly, things last much longer……………. FL2 SD4 HSE Lux Auto MY 2012— current

On NSW outback roads, even with a bit of rain, they turn into a bar of wet soap. You clearly hear the ABS working overtime. Have to turn off the stability control.

We slid off the road dozens of times. Only when we hit the scrub on the side of the road did the car get grip. Then go through the whole process again.

The roads do get closed & there are fines if you drive on them. We got through before closure.

If you have never heard the ABS. Go to a quiet safe road & plant your foot on the brakes as hard as possible. You will then understand what is going on.

If you drive sensibly the brake pads last a long time.

My Peugeot 504 had discs, everything was the same size on all four corners. The rear pads lasted about 3 times longer. I drove that car like I drive the Freelander.

I did get the pads reshoed with metal pads. They were a green material with what looked like bits of aluminium in them. Probably the green was asbestos! They braked really well & basically no dust lasting a very long time. Procrastination, mankind's greatest labour saving device!

Here in the Hautes Corbieres I use the HDC control quite often on steep descents…….occasionally off road…nothing too damaging, but the noise from the ABS motor & valves is incredible……..that was my point: the stability systems work but you will know when you have activated them………they don’t just apply à brake to à wheel or wheels without the driver knowing………………unless the driver is deaf……. FL2 SD4 HSE Lux Auto MY 2012— current

A good point OxonPete.
HDC does make a racket as the individual brakes go fully off and on.
I cannot find a full answer to how they control stability, but I understand that the ABS pulses extremely quickly and with the wheel speed sensors finely control individual wheel speeds.
From my experience of entering a large roundabout between 2 motorways too quickly, not much noise, just a 'floaty' feeling as the FL2 reduces power and widens the turning radius slightly.
I have always found the FL2 brakes to be very good, even in emergency braking situations. FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

IanMetro ……I agree thé FL2 brakes seem very good although, luckily I have never had to use the brakes & stability aids in an emergency ‼️ I know the HDC works & thé ABS /TC has worked when needed but the snag with all the safety systems is you hope they work should an emergency situation be encountered….!

Lightwater……your low-profile tyres are obviously nice & grippy…….!
Just watched your video on Vimeo ……those soapy roads look more than ‘interesting’……!

There is a difference in ABS operation when emergency stopping or stopping on slippery surfaces and when operating in stability control. The first case is full on cadence braking, so the ABS goes from maximum pressure on to lock the wheels to off far quicker than you can do. In stability control the brakes are gently applied to correct the instability and are controlled by accelerometers which actually sense the instability before anything happens.
Normally you would never notice it working, but it allows you to corner much faster than you should and apply brakes in a corner when you shouldn't, in extreme cases you may feel the ABS braking, it is generally accepted that LR stability control is one of the best systems if not the best.
There was a Top Gear program where a FFRR was set against a BMW X5 on a wet grass slope on standard tyres, the FFRR proceeded further up the hill by about 100m, so BMW didn't get the full program of stability they bought LR for and I doubt Ford did either.
Those same accelerometers allow the built in Nav system to dead reckon your position in one of those tunnels on the Paris by-passes so you come out of the tunnel in the lane you want. my PC is slightly to the right of Genghis

Thanks Dartman the one for your very interesting & informative post……..
Despite having driven thé FL2 for 13yrs I didn’t realise that it was equipped with the stability control to such a high level. I have researched à bit more about this DSC…..Dynamic Stability Control using the same technology as my previous Disco 2 with ACE….Active Cornering Enhancement…with the accelerometers sensing the start of body roll. It was a great system, unbelievable cornering capabilities for such a big vehicle, surprised quite a few following sporty types round thé twisty bits. Unfortunately very rapid tyre wear ensued if you pushed it & thé wife didn’t like been thrown about. I had to replace all hydraulic pipes & valve-block…corroded like the chassis.
I have found thé FL1 to be much better in a lot of ways, no ABS faults, very few problems..haven’t needed to see if the DSC really works in an emergency…….reassuring that it has such a good reputation for crash avoidance. I believe you would still hear the ABS system noise if activated but I guess would be busy behind the wheel not to notice. From IanMetro’s posts I think the DSC must have activated for him !
I remembered someone else having a problem 6+ years ago…..with an identical car to mine ( that’s why I remember). Thé Duke of Edinburgh…….I wonder if the DSC worked…..at least he walked away from it…!

I think that I activated the 'Roll Stability Control' which is always on.

I decreases the power and applies the outer rear brake to increase the turning radius, hence the strange floating feeling.

In my defence I have to say that it happened not long after I changed to the FL2 from a more normal quick (and lower) estate car. I have learnt to be more gentle with the FL2 and employ an (almost) exaggerated slow in, fast out, approach to corners.

I think that the FL2 is cleverer than most other so called 4x4/SUVs, and has a whole load of interconnected sensors and systems, FL2 XS SD4 Auto 2010 2012-2017 (21k - 91k miles) (MY2011)

I did quite a lot of research into the Freelander 2's various onboard safety systems and traction aids and put together a long video about them which anyone can see here : https://youtu.be/UzBCvFJKxwM?si=QnHEKcywazHk96Eo&t=763

In some of the clips you can see an individual front wheel get braked as it's trying to move torque to the other side when it's going up and around some corners. You won't hear any sounds from the ABS system in those circumstances.

From what I've seen from the Freelander 2 manual it looks as if there is an ABS unit and a HCU (hydraulic control unit) as part of it / within in. Like Dartman the one has said, the ABS does its thing when it senses a lack of traction. When it comes to things like...

Corner Brake Control (CBC)
Dynamic Stability Control (DSC)
Electronic Brake Force Distribution (EBD)
Roll Stability Control (RSC)

I think that is handled by the HCU unit (with help from the ABS when things go really wrong ) which can apply braking forces to individual wheels if needed without the driver even knowing about it. I think a lot of this is probably done mostly on the rear brakes from roundabouts as the car's weight moves from side to side and the brakes gently apply to keep the car as neutral as possible without interfering with the driving experience.

Although it does make me wonder if there's anything related to braking forces that can be monitored via live data on an Autel. If so, it would be interesting if that could show the systems at work and how much they work... Food for thought. https://www.youtube.com/@scottandalana4x4
