There is one more reason why the handbrake ecu needs to communicate with the ABS ecu, and it is not mentioned in the video, and that is the emergency braking. If the car is driving normaly on the highway, and there is the need for emergency braking, and for some reason we can't use the brake pedal, an emergency braking can be performed by using the handbrake switch. By pulling the switch and keeping it pulled, the driver informs the hanbrake ecu that he needs an emergency braking, the hanbrake ecu immediately communicates with the ABS ecu, the ABS ecu applies the brakes, slowing down the car, and when the speed drops below 15 - 20 kph, the hanbrake ecu pulls the cables and applies the brakes, effectively stopping the car.
Really really apreciate your video , it's incredible how complicated have become the systems in modern cars. By the way I still can't understand why car manufacturers insist in turning a simple and reliable handbrake cable into an electronic device.
True that brother. Beats me too. I bet it has to do with what buyers want. They just try to approach as many buyers as they can, and your typical driver, (even in the 21st century unfortunately...) is not the one who knows how to drive, but the ones who think that a car is another smartphone. It just doesn't fit in your pocket. People like to press buttons and stuff, and we see so many models having touch screens and all, making simple things even more complicated. Total douchebagery if you ask me. I still love my cable handbrake in my GS.😂😂😂😂😂
If You check TH-cam, You se all those fools , often americans,forgetting to pull the handbrake and running after their cars 😂 That is preventid with electric handbrake
Hm, Please Watch/read all the messages about electric break system capabilities and functions again folks😉. Impossible with hand operating I am afraid…
Very nice instruction. I have personally changed the rear pads without the lexia computer. Just release the handbrake, lift the positive batteri connector and do the change of parts After reconnect the batteri and turn the start key so the the instruments light up whithout starting the engine. Wait for 2 minutes, Turn the key to off. Then start the engine, press the brake 2 to 3 times to set the pads. Never any problems with this procedure
Well good to know, you've tested that method, so that others won't have to. And seems like it's working. Others have tried it too, and they also didn't have any problems, so yes, good to know there is an alternative. I think it's more important to know that new pads need to be sanded before installation. If they are not sanded, and installed right out the box, they leave a peculiar residue on the rotor, probably from some kind of coating from the factory. So always sand new pads and rotors. ALWAYS. Thanks for the feedback. 👍👍👍
Well thank you and welcome aboard. The lighting is an issue I hope to fix with a light I'm planning to get soon. Good thing the only dark places were not "that" important. That garage isn't lit good enough for a camera. And you can't realy do that kind of work outside. I do hope the english translations on the steps of the diagnostic tool, were making sence. Cheers.
Καλέ μου φίλε, καλά να περνάς, που θα πάει, θα τα πούμε κάποια στιγμή, θα έρθω με το παλιό αυτοκίνητο να δείξουμε πως κάνουν ευθυγράμμιση με το αλφαδόνημα. Καλό Πάσχα.
Absolutely brother. It is needed. Since the new pads have different thickness, the handbrake ECU needs to know the new thickness, so you still need to calibrate them. Thanks for tuning in.
Actually no. I replaced my rotors and pads recently and you absolutely do not need to calibrate anything, you don't even need the scan tool. Just disengage the parking brake, disconnect the battery, change the rotors and pads. Some forums said to pump the pedal a few times before starting the car. The car adjusted to the new pads instantly, no calibration needed.
@@tomaskusnir2374 .....well thanks a lot for the information brother. I honestly didn't know that, and since the diagnostic tool has the calibration function, I figured that it's there for a reason. Also, the official Citroen Backup Documentation, the same documents the dealerships have, mention specificaly that changing either one, (pads, rotors or both), recalibration is needed through the diagbox tool. They state it clearly in the official instructions they give to their dealerships. That is the only reason I didn't know about the method you describe. I figured, since Citroen states it clearly in their instructions to their dealers, there must be a reason they want the electric handbrake recalibrated after every job. That's why I mention that method in the video. It is the official Citroen method, according to their official instructions, to their official dealerships. As you can understand, since I set off to make a video describing an official method of operation, I couldn't realy show "experimental" methods. Since you tested it in your X7, and it works, and it doesn't "break" anything, and also nothing happens to the handbrake ECU, and as long as it's safe AND......it can stand the test of time, then I guess the information can be realyed to the public. I don't want to spread any misinformation. You understand the position of the creator, right? Thanks for the additional information. Good to know.👍👍👍👍
Ναι, σωστόν. Η Σιτροέν στις οδηγίες της αναφέρει πως η εργασία γίνεται αφού πρώτα τεθεί το χειρόφρενο σε θέση "αποσυναρμολόγησης". Και μετά λέει "αποσυνδέστε τη μπαταρία". Δε γράφει τίποτα για αποσύνδεση του διαγνωστικού ΠΡΙΝ την αποσύνδεση της μπαταρίας. Το αναφέρω και εδώ, και στην Ελληνική έκδοση του βίντεο, μετά την εργασία, μαζί με τις υπόλοιπες επιπλέον πληροφορίες, που καλό είναι να γνωρίζει ο κόσμος. Από το λεπτό 16:00 και εξής, το πρώτο θέμα που κάνω λόγο είναι αυτή ακριβώς η ασάφεια της σιτροέν, γι'αυτό και προτείνω την δική μου εκδοχή, καθώς την έχω δοκιμάσει, δουλεύει σίγουρα, δεν προκαλεί κανένα πρόβλημα, και δεν χρειάζεται αποσύνδεση της μπαταρίας. Η δε βαθμονόμιση μετά την εργασία γίνεται με τον ίδιο τρόπο, και δεν υπάρχει φόβος με το που θα ανοίξουμε τον διακόπτη, να τεθεί μόνο του το χειρόφρενο σε εμπλοκή. Παραμένει απεμπλεγμένο όπως το είχαμε αφήσει πριν κλείσουμε τον διακόπτη, πριν ξεκινήσουμε την διαδικασία. Συνεπώς η απάντηση στην ερώτησή σου αγαπητέ, είναι "ναι", σωστή η οπτική σου, απλά είναι λίγο μπελαλίδικο, και δε βλάπτει να γίνει η αποσυναρμολόγηση μόνο μία φορά, "μετά" την εργασία. Ίδια δουλειά γίνεται. 👍👍👍👍👍👍👍

On the other hand I do miss my handbrake too🥲

Really a top notch tutor and video although a bit dark in places!

Thank You for all that detailed explained process! It has helped me a lot with my breaking pads job😉👍😄!
Nice to hear that. Glad to help good friend. 👍👍👍
The best video in this regards. Thank you
Well thank you for visiting. Hope it helps.
Great video, helped alot
Καλημέρα φίλε μου να σε καλά

thx very informative
Glad to help. 👍👍👍
It worked, thanks.
Awesome!!!!!👍👍👍👍👍👍👍👍👍

Η ύπαρξη επιλογής τοποθέτησης χειρόφρενου σε συναρμολόγηση/αποσυναρμολόγηση μήπως είναι σκόπιμο να χρησιμοποιηθεί πριν οποιαδήποτε παρέμβαση?

Please get a new camera
hahaha.....it's not the camera that matters but ..... the passion... ! ! !
(besides, the power bill got all my money....😂😂😂😂)
@@mr_nice. Fair enough. The slight blur you have with 720p is enough to not make this viewable.
