In normal driving use I like them, it took some getting used to but now I've come up against a bit of a problem.

 

I wanted to put the car on some front ramps to remove the undertray and clean up the area. On previous cars I've used clutch control and the handbrake to get up on the ramps slowly without any danger of going too far forward.

 

Without a conventional handbrake there was a great danger of overshooting once on the top. Don't believe me, try it! I had to use normal jacks in the end, too frightening to drive up the ramps.

 

OK, I'm a wimp

Doesn't your Pic hold the brakes on for a few seconds after you take your foot of the pedal when facing uphill? I've managed to get mine up on wheel ramps without any issues.

Are we talking manual or auto here.

With manual you can keep complete control by using your right foot to control the footbrake and throttle at the same time. Just a bit of practice needed!

But creep control on the auto is near impossible- even on level ground. That said, it can be done by co-ordinating foot brake and throttle. I need to use this method to ease my auto forward onto the car wash conveyor track.

 

There is a big plus for this 'clutch slipping' method on the auto-it also solves the juddery clutch issue without resorting to the Italian tune up.

Loved the auto-handbrake and hill start assist until the day my car decided to go into limp mode, the recovery guy wanted to use suspended tow with the front wheels raised off the road, the easiest remedy to do this was to run the engine to stop the handbrake actuating until we reached the garage

It is possible to release the electronic handbrake without having the engine running.

IIRC there is a way to manually release the handbrake in an emergency with a socket or something, but it needs to be reset using Diagbox, I think there is info in the handbook.

There should be a thin winding handle in the boot with the spare wheel, think you have to use it somewhere in the passenger footwell to wind off the brake, no idea what happens after that

Surely it is just a case of- Ignition on[engine not running], depress footbrake, pull on dashboard switch, ignition off.

Hand brake will remain off till next startup. Don't forget to chock the wheels  :mellow:

From what I recall there is some interaction between the engine [possibly just the throttle when the engine is running] and clutch [with the car in gear] to disengage the handbrake, stopping the engine  either on the key or stalling it, re-engages the handbrake, dont think just using the ignition key does anything

So, I just tried it on mine- and yes, the handbrake goes off using just the key and the footbrake.

Its something I never tried while I had mine, only aware of the winder

As I understand it, the winder would only be used in a situation where the ignition/brake sequence did not work e.g. no electrical power.

And I think that after the winder has been deployed the car has to go on Lexia. Not a good option after a simple rear pad change.

 

However I have heard it whispered that the handbrake will reapply under certain conditions. Apparently issues can arise when the car is being let down on a 2 post lift, the type where 4 arms are positioned under the sill jacking points. I have heard that as the wheels touch the floor the brake comes on. The wheels are now not free to revolve and the car tries to move on the supporting arms causing damage to the sills.

 

Now this makes me wonder if the handbrake might reapply whilst being towed and whether the battery should be disconnected in some situations.
