XC70 Electric Handbrake - Page 2

Well that's good to know. The only quibble I have with the EPB so far is that the operation seems very counter-intuitive. I instinctively try to "pull" the button to engage the brake, just as I would with a conventional lever. Still doing this even after 12 months ownership....probably says more about me than about the system...

On a separate but related matter, can I use the EPB as an emergency brake whilst travelling at speed? Heaven forbid but you never know... AG

Apparently you can - but I've never needed to - or dared to...!

I've never tried it, so I can't confirm for sure. I wouldn't advise trying it though, in case you end up in a place you shouldn't!

If you needed to stop quickly in an emergency, why would you select the EPB? Without stating the obvious, its an electronic parking brake, not an emergency brake.

Surely if you needed to stop quickly, you'd slam on the brake pedal and not touch the EPB? I would have thought that would be more of a natural instinct.

Here's what it says in my 2011 Owner's Manual about using it when moving:

simboc2004 · Apr 23rd, 2024, 08:59

So you can use it when moving. If you do it brings front and rear brakes into play (how?) until nearly stationary, when it switches over to only the rear brakes...

In an emergency it can be applied - if you depress the accelerator pedal, or release the brake button, it will then disengage. Which, i presume, means it doesn't lock on if you are moving and press it - you have to continue to press it in for it to work... And it makes some kind of warning sound when you engage it at speed.

All as clear as mud, then...

Hand brake turns?

apersson850 · Apr 26th, 2024, 09:12

No, you can't do handbrake turns. If you press the parking brake button with a speed above 10 km/h, it will just apply the running brakes in a normal manner. It doesn't know how hard to press, so it applies them fully which means you get the same effect as if you try to press the pedal to the floor. Full brake interrupted by ABS.

It runs as long as you press the button or until the car has almost stopped. If you come down that far in speed then it applies the parking brake in the normal manner.

As long as you press the button there's a pling-pling sound going on together with typical ABS rattle.

The seemingly inverted operation of the electric parking brake is due to Volvo's desire to make it as consistent as possible. You pull to release just like you do with the cars that have a parking brake pedal. There you pull on the handle to release, and since this handle is in the same place it works in the same way.
Which in turn means you have to push to apply, since the "pull" operation is already assigned to release it.

That's the opposite of my Range Rover Sport - gets confusing sometimes swapping between the two...

Given the position of the parking brake switch/lever, having it as an emergency brake operating on the normal footbrake circuit seems a bit pointless.
unless i were to suddenly be aware that i had lost the use of my legs whilst otherwise fully functional having to reach down below the steering wheel when there is a perfectly positioned brake pedal does not make sense. and if i was about to collide with something i would want my head as far from the airbag as possible.
conversely LandRover place the lever in the centre console where the passengers can get to it & pullling it up makes sense - though this might have its draw backs too. A bit disconcerting at 80mph - on a test track demo day not the road fortunately.

I doubt the people at Volvo really saw it as an emergency brake. Rather a fallback system because they could, not because it was too realistic. Perhaps if someting on the floor rolled in under the brake pedal.

Pulling the mechanical brake in the old days wasn't too realistic either, since there was usually one out of two possible outcomes of that:

Not much happened.
The car flipped around on the road.
