electric parking brake.

Post by civvie »

All you lasses and lads who have this on your Citroen or Peugeot. I have just had my Mot done and last year it only just scrapped through on the handbrake, this time there was shaking of heads by the tester and he said it could fail on the handbrake, I then remember something John (jgra1) said, if you get the tester to turn the engine off the handbrake will pull on harder, told the tester this, he did it and lo and behold a good strong reading, the tester said he would be happy with that, and it was something else he had learnt. Everyone was happy. Passed with flying colours.
Thanks John.

Strange bloody things. What is wrong with a lever between the seats?

My tester said NEVER apply the handbrake with the double pull (panic mode) on the rollers, he has seen a few problems after the test with stretched cables. He thinks the electric parking brake is exactly that [parking brake] and, not a stopping brake.

As the rollers are designed to show the capability of hydraulic brakes (and also offer VERY high tyre grip) he thinks the rollers overload the electric brakes.

I'm interested in the reasoning behind the last statement, how the rollers could overload the electric brake exactly, bearing in mind the electrical part is only an actuator and the friction side of the brake itself is still mechanical? do they apply more tension to the cable based on if it detects a wheel moving or something? I always assumed an electric handbrake was either fully on or fully off, or maybe more modern ones are less "binary" now in that respect...

And regarding stretched cables, surely such a safety critical item should be spec'd by the manufacturer to be able to deal with the full tension that the actuator could deliver? As you can tell, I'm not au-fait with such things & certainly not rubbishing anything that's been said just interested to know the thinking behind it.

The thing that turned me off electric handbrakes was when Renault informed me of a recall because handbrakes had been activating at high speed on the motorway!!!

Ok all, so why is the reading higher when the engine is turned off, as far as I know the tester didn't use the double pull as said by sticky. People may say whats wrong with the handle between the seats, I suppose that's the way car makers are going and sooner or later everyone will more then likely experience it.
Looking on t'internet about this on the testers web site forum there is mention of referring to the the manufactures instructions on vehicles with electric parking brakes, anyone have access to this info for Peugeot/Citroen.
