Electronic handbrake

Obviously a tall story or driver error, if the vehicle was in P the EPB and Parking Pawl would be applied and if it was in D either the footbrake would be applied or if moving the EPB would be released so the driver would be in control or not as the case may be.

You wont find many cars without EBP these days and not just new ones, our 2017 Santa Fe had it and was faultless in manual or auto.
On our XC90 you have various parking brake options/combinations.
1. Using the Sensus system the EPB can be auto applied everytime you stop in traffic aligned with the engine stop/start function - brakes release very sharply making it a bit jerky in slow traffic - Option not used
2. A button to activate the auto hold/EBP system - see 1. - Option not used
3. Another button to apply EPB on and off manually but will auto-release if pulling away.
4. Using Sensus system the EPB can be set to apply when the engine is switched off at the ignition button. This option is selected and probably the only time the EBP is on
All options of EBP auto release on our car are not the smoothest so is turned off manually manourvering the caravan.
Strangely though hill holding and hill starts with or without caravan attached are very smooth!
The XC90 B5 engine stop start cannot be turned off but is seamless unlike the EBP release.

To find out what the failure was you will need to contact the driver or the breakdown service that attended the Range Rover
I am just advising of what was conveyed to me over a drink with the site staff concerned ,but some it seems try to make it a major issue
The actual conversation was the way the cost rose to repair the bollard since the latest contract with caravan site electrics had been implemented

It's hearsay, JVB. You have no idea what caused the incident so are blaming the EPB without evidence.

I can only assume that EPB are cheaper to fit as I can't see any practical advantage of them compared to a "normal" set up. I know that in the case of my Merc they removed the drum parking brake when the EPB was introduced & so the EPB now acts on the disc. And you only need to look at some PSA cars a ffew years back to know that drum parking brakes are better than discs.

Some months ago a neighbour with a VW 4x4?,his vehicle. ran into another vehicle about 50yrds down the hill of our road
And more"hearsays'
the owner of the VW told the owner of the damaged vehicle who told me
the epb failed to hold the disk brake on his car as the brakes were hot and had cooled down allowing the epb to not grip fully after application (VW garage answer)

When you stop.
Seriously though, I've had cars with EPB, and find them simple to use. It comes on automatically at junctions, and stops the car from rolling backwards. Brilliant. I then went back to a conventional handbrake, and hate it. I'm always forgetting to pull it on and now have bruised ribs from being prodded by my wife.
Got a new car coming in the spring, and can't wait

In my ML I have a foot brake. I have a rarely used EPB that is applied when I apply it (generally) & I have Park. When I stop at lights etc I either just keep my foot on the brake pedal or give it another shove to enable 'HOLD'. HOLD will stay on for ever & a day until I shove the brake again or press the throttle. I left foot brake so if faced with a hill I have a foot for each pedal. I don't want or need an EPB to engage each time I stop at a junction or traffic lights.
My other cars have a conventional handbrake. But still only 2 pedals.

The fault then is you forgetting to use the conventional handbrake ..... a bit like an auto driver forgetting to dip a clutch or change gear. Not a fault of the vehicle. 😉
I find my EPB simple to use ... push the switch for ON & pull to release. But I don't roll back, even on a hill because I have a foot for each pedal .... Even if you don't routinely left foot brake, there's nothing to stop you from using your left foot to hold the vehicle when on a hill & use your right for the throttle. Do you seriously apply the handbrake each time you stop? Was I taught to do that 40-odd years ago? I can't remember, but don't think so. 🤔

I'd gone to the main dealers & saw something like this being loaded up back onto a HGV after it'd just unloaded the recovered car. The recovery bloke said that failure of EPB was a fairly common fault on cars in general & when the car is on a multi-storey car park they can be a nightmare to collect. So they use a robot like this! A few quid's worth I would think.

On the Land Rover Discovery and similar series the Electric Parking Brake operates on the rear wheels on a combination disc and drum. If the driving brakes have been used a lot preceding park brake application that combination will have expanded, and as it cools, contract onto the parking shoes.
Perhaps for this very reason Land Rover provide an emergency manual release which is hidden away in the centre console even more than it is hidden in the handbook. It involves pulling heftily on a wire cable.
Where manual parking brakes (usually) involve a straight pull on a cable with a lever, the electric ones pull the cable by winding it around a drum. Sometimes it does not wind on evenly and jams on release. And just to complicate matters, when low range is in use Land Rover cause the drum to tighten further than otherwise. Some people use low range when manoeuvring in tight spaces such as car parks.

the same set up as a lot of cars were. My Senators & Omega and my previous R Class were this 'top hat' design. As suggested above, perhaps MB saved a few quid when they fitted an EPB to my ML

electronic parking brakes are GOOD
you want a hill start, no need to touch the brake switch
select your gear, let out the clutch, add a bit of accelerator and the brakes come off
you don't need a hill start function
the only downside is you can't park in the garage with the handbrake off, you take the key out and they come on

I'll never forget my first Auto after 20 years in a manual.
The day I picked it up I thought I'd see how well it accelarated (company car!). Of course it dropped down the gears, but I was ready to change up before the car was. Forgetting it was an auto I stamped on the 'clutch' and performed the harshest emergency stop ever. The bloke behind me almost soiled himself, as did I!
We both pulled over, and he gave me cigarette, even though I don't smoke. Boy, I needed it.
After that, I drove without my left shoe on until I got used to it.
