Electric Parking Brakes (again!)

So PH experiment please.
Do any of your cars, manual or electric parking brake, cause the brake lights to come on when activated?
Pretty sure none of mine do.Do any of your cars, manual or electric parking brake, cause the brake lights to come on when activated?
Please don't try your "passenger pulling on the handbrake trick" in an old Land Rover or Range Rover as the hand brake works on the transmission and is not designed to be used when the vehicle is moving.

Apparently there was something wrong with it otherwise they wouldn't have replaced it with a complex, expensive, integrated system that isn't very intuitive and when it goes wrong is difficult and expensive to fix outside of a dealership...
Of course there was something wrong with it. It didn't have any computers involved. We all know that everything on a car needs to have computers involved these days, otherwise it's - well, frankly - just so previous-model. And that would NEVER persuade punters to upgrade, would it?vit4 said:
Honestly though, I can't think of a more pointless feature on a car. There was literally nothing wrong with a conventional handbrake 
Conventional handbrakes on heavy cars with rear disc brakes are a bit hopeless in my experience, and only just up to the job of holding the car... Plus plenty of cars do roll away due to handbrakes not being fully applied, even if it is up to the job.That and the packaging advantages of not needing a long lever in the centre console or cables running from there to the wheels with no sharp corners are why they've spent a lot of money developing and fitting EPBs.
Like I said, I don't particularly like mine and would prefer a conventional handbrake (the car isn't too heavy, so it'd work fine), but EPBs aren't entirely a bad or a mad thing.
my old mans 3008 has it, I bloody hate the thing.
it must be linked to the reverse park sensors, if you reverse into a space with another car/wall/bollard behind the beeps go as expect and stop just as it become a tone.
Gets out, 2 foot gap, gets back into, engine on, clutch down, select reverse, disengage E-Brake, disengage E-Brake, disengage E-Brake, disengage E-Brake, bloody disengage you POS, select 1st, disengage E-Brake, select reverse, take up last 2 feet.

To dispel some myths:
In the UK passenger car brakes are governed by the ECE 13h legislation. This means that any car MUST:
- have a secondary braking system (ie park brake) capable of holding the car on an 18% slope and decelerating the car at 0.15G.
- It must stay applied with the battery disconnected (ie they don't use power to hold the brakes on)
- There's a limit to the max force that can be applied to the control to hold the vehicle on the 18% slope.
That final one means that with our increasingly heavy cars it’s not easy to have a manual handbrake anymore, the lever would be too long (ie cranked as in many cars). This plus the increasing need for cupholders in the US market means there simply isn’t space for a long lever in the cabin.
The other thing is that there’s less maintenance, the thing is self adjusting so the fleets like it. Any decent garage can back the pads off with a laptop, though there is an impact for the back street garage who don't know how to service them properly, that's the same with any modern car component though.
All will have an emergency braking function (see above!), many through the slip controller/foundation brakes. In the event of a foundation brake failure they will act independently on the rear disc only.

I've never, ever heard of parking brakes causing the brake lights to come on, on anything.
Don't you think that it might be a good idea if as some posters have said, operating the electric parking brake while moving activates full ABS.Imagine travelling behind when someone mistakes the brake switch for the electricwindow switch!
