It doesn't really matter in all honesty when not using the easy scan tool. But when using the easy scan tool and bleeding the ABS brake system, it takes you through the brake bleed process, operating the valves within the ABS valve block in order to bleed the brakes. I should have explained that better within the video. 👌👍...
Now that was a surprise, was expecting to watch this next Sunday. 😅 I was surprised that you went around the van rear, front, front and rear as I've always done furthest away first to nearest to master cylinder last. Also surprised it only took you three goes to get a pedal as I spent hours doing my MK4 and lost count at how many attempts it took me. 😅
No, we need to get back on with the van Re-build bud, I bled the system as the Iveco Daily Workshop manual instructs you to do for the ABS system. I have done it the same way as you before, I can't say either is better as it's still a pig to bleed these brakes 😂👌👍👍👍.
Cheers David, Yes, I wouldn't be surprised as the canbus system is much complicated upon the mk4-5 too. So whether it's to tie in with that I don't know🤔. Cheers matey 😉👌👍👍👍...
So when the ABS operates, where does any air go? As far as i can see it stays in the system? One or two cars makes, notably some Hondas, are designed so that when the ABS is activated with a diagnostic computer, trapped air is directed to one specific brake line - so that it can be cleared at the bleed nipple.
Yes, I did wondered this at the time too, so I looked up the bosch ABS unit that's fitted upon the van, within the workshop manual and it appears, when the ABS unit is being cycled, under a closed loop system it manages to self-vent any trapped air back to the reservoir via the valves that are being operated ( from memory, 6 valves ) within the ABS valve block whilst cycling, looking at the ABS hydraulic schematic within the manual, it makes more sense ( visually ) on how this works rather than the explanation provided within the manual. In an ideal world, we should be bleeding the brakes via the Easy Scan diagnostic tool ( the last time that I looked, these units were around £3000! ) which takes you through the brake bleed process that I've shown and cycles and operates the valves within the ABS unit during the bleeding process. However! This issue only happens when the brake system has been bled completely dry ( like, when changing brake pipes, where you can't really help, but let the brake fluid drain out of the system ). so, if its only the case of changing the calipers and the brake flexi hose have been clamped off, it should be a simple bleeding process without worrying about the ABS system, like it was on mine during the video 👌👍
@@Iveavan thanks very much for your reply - good to know. I had an issue bleeding my Pug307 (2006 model) - just hell it was, after a caliper and pipe change - tried suction bleeding, pressure bleeding, the lot but nothing would go through, even though Peugeot (and others) assured me fluid should fly through like that. Eventually, we stripped the front off the car off to get to the ABS (French cars!) and cracked open its pipes one by one and as we did so and this pressures changed, the ABS motor could be heard running (no computer attached). A thin brake fluid with micro air bubbles came out and after letting it settle several times and rebleeding it the same way we got it to work and the STOP light went off on the dashboard. We could not get any air out at all at the calipers - it was just clear brake fluid as it should be. Peugeot added that they sometimes use a computer but it shouldn't be necessary - if I understood that part correctly. Best of luck mate.
Yes, you're right! Regarding bleeding the furthest bleed nipple away from the brake master cylinder first. My van has ABS , so I followed the 'Iveco Daily Workshop manual, brake bleeding procedure for the ABS system' ( this was mentioned @3:31 within the video). Starting at the N/S rear Calliper, ( furthest away from the master cylinder) working myself around to the N/S front Calliper, then onto the O/S front Calliper, finishing on the O/S rear Calliper. 👌👍.
Which caliper did you change? Front or rear? Did you clamp off the flexi hose before changing the caliper so the brake system didn't blead dry? Does it have ABS or a load-sensing valve? I presume you exhausted all of the air out of the system?
@NegrutOctavian unfortunately, because the system has been bled dry, it's going to be a bit more of a pain to bleed. But if you follow the process that I've shown within the video ( preferably with a brake bleed pressure kit ) until you see all of the air has been exhausted and you've adjusted the rear brake caliper to close up the air gap on the brake pads and the hand brake adjusted, once bled, carry out that short run up on loose gravel and apply brakes until you feel the ABS pump kick in and you should feel the difference in the brake pedal. If it's got new brake pads, it may feel like it has a longer brake pedal travel until they have been bedded in 👌👍.
@@Iveavan Thanks for replying. I think I’ll get one anyway for what it costs. Just replaced calipers and the pedal sinks, so gonna try your skid trick and re bleed. I think the best thing is you can view the bleed pipe, otherwise your in n out pumping, when on jack stands also 🫣 really appreciate your vids btw. Cheers 👍
Thanks for being the go to guy for honest opinions and great solutions
No worries, Sean & Thank you 🙂👌👍.
Mate 2 videos in one day. You're spoiling us!!!!
Haha 😂😉👌👍👍👍.
I made one using a schrader fitting and tyre pressure and adapted a brake fluid cap...basically one pipe from tyre to cap...works really well! 👍
Excellent detailed explanation. Many thanks.
Maggie and Mack, Huddersfield
Thank you again guys, very much appreciated 😊👌👍👍👍.
more good info mate
have to do this soon on my van
cheers
No worries bud, thank you! 😉👌👍👍👍.
it's good to buy a car from responsible people like you 👍👍👍
Thank you matey 😉👌👍👍👍.
Very helpfull
Thank you & no worries, Martin 🙂👌👍.
Excellent 👍👍
Cheers Jonathan 👌👍👍👍.
thanks for that . I just wondered why you need to turn on the ignition ?

Awesome bud cheers 👍🏻

Your video's are very helpful i noticed they changed the ABS pump after mk3 is the sequence still the same on a mk4

how come u bled wheels front to back people say u should work fur
est away from the slave ?

hello, I changed the caliper and now I have no brakes, the pedal is soft all the way to the bottom
Which caliper did you change? Front or rear? Did you clamp off the flexi hose before changing the caliper so the brake system didn't blead dry? Does it have ABS or a load-sensing valve? I presume you exhausted all of the air out of the system?
@@Iveavan the right rear caliper and I didn't tighten that hose the fluid ran down the floor
@@Iveavan please help me!! 😢
@@Iveavan has abs

Do you need to use these pressure bleeders, or are they just easier??
It's just easier if you don't have anyone available to operate the brake pedal whilst bleeding the brake calliper 👌👍.

Great job you little bleeder lmao
