iveco handbrake

[Burnerman]

Hi Brian
Wow - those discs are in some state!
I'm trying to familiarise this set up with a similar one from a Transit twin wheeler.
I think the shoes within the disc can be adjusted through one of those bung holes in the rear. As the holes aren't near the periphery of the drum its unlikely they are only there for inspection. Can you see or feel any sort of mechanisn when you poke a screwdriver through there?
On the first pic, it should be possible to remove the disc/drum from the axle but a large puller will be needed, and the rust is severe so it will be stuck fast.
One of the Transit tricks was to knock one of the wheel studs through into the drum, to allow the adjuster to be undone and the drum removed.
Now, this is just guesswork by me, as you can probably tell.....is there an Iveco dealer close to you?

If its the same as the 406 the hole is very small and you can't see the adjuster unless you shine a light into it and even then its not easy.

Ok well I had a look and couldnt see anything in there but that doesnt mean there isn't. When you say an adjuster what are you refering too as I have adjusted the cable tensioon with the pulley in the centre of the van. Im wondering if its worth just removing the disc/drum so I can see for sure but as you say its 'dated'.
I might be able to get hold of a puller but I need to know how to remove the disc/drum as I've already removed the ring of nut on the end of the axle to no avail.
Sounds like this job is going to be a nightmare.

Also thanks Peter too.

The adjuster is a toothed wheel which you turn by pushing a screwdriver against it. I do believe there are several different types, if you can't see a hole yours may have an auto adjuster.

These handbrakes don't seem to work very well, I just bought another 406 for a friend and his is the same, you have to pull it up very hard to hold and its better forwards than backwards.

There is definatly a hole there at the bottom (and top). I will have to have a better look tomorrow. As I said I thought it may be that the cable was too lose but I adjusted that so the handbrake only clicks about 4 times but it still doesnt hold the van. In fact I can actally push the van so it doesnt hold at all. Im dreading taking it to a mechanic as I had to have a front brake hose replaced and they charged me 183 Euros.

You are looking on the front of the drum, behind the wheel? There is only one hole in mine, you will need to shine a bright light into it to see the adjuster, you will need to rotate the drum to about the 10.00 clock position, you need to do this slowly as you can easily go past it. Before you adjust the shoes slacken off the cable tensioner or it may stop you from adjusting the shoes right up, adjust them so they are just scraping the drum, then adjust the cable again.

Ok
I would firstly like to thank everyone who has posted on this topic.
I have managed to fix the problem and I'll explain how in case anyone else comes across the same problem.
Basically the handbrake wasn't working at all but would ocasionally stick in reverse. I adjusted the cable tensioner by the pully on the underside of the van in the middle which tensioned the cable but still didnt apply the hand brake.
Removed the back wheels (2) to realise that it was a foot brake pad system with hand brake shoes.
Eventually looked round the rear of the housing to see the little hole at the bottom (that everyone told me about)
Through this hole I managed to suss that there was the cable coming in which had a fixed hole on the end and also a lever with a hook (which attached to the shoes). It appears that as the handbrake had been left on, the lever had ceased and when the brake was removed the cable came off the lever. As its a pully system there was then no tension to operate the handbrake on the other rear wheel.
I tried to free the lever through the hole but it was a pain in the ass so I removed the bung that the cable passed through and was able to work the lever back and forth through both holes (with a hammer and screwdriver) until eventually it freed up.

Hope this helps someone.

Thanks

Brian
