Hmmmm :chin: I think you're find a lot will disagree (n)

Several horror stories of wreaked calipers on the Forum to convince most people :eek:

Sounds to me like you just got lucky (hopefully it will stay that way :))

I dont think i was lucky, as the tools that are used are really no difference from pliers, its just that they are stuck in the correct position rather than you manually holding them at the correct position...and in my eyes the special tools are worse, let me explain.....if you use long nose pliers you can feel how easily the callipers turn, where as if you use the tool connected to a socket/spanner it would be so easy to use to much force and twist the calliper when it may be stuck.
Put it this way, if it will not turn by hand (plier) then there is a chance that the calliper is ceased and neads an overhall, you wouldent know this by using the force of a spanner...
anyway thats just my opinion, maybe you agree, maybe you think im wrong, but thats just how i see it...
On this point i would like to say i DO still like specialized tools in other mechanical car areas....

And the comment about other horror stories of damaged callipers, maybe thats due to lack of knolage, experience, or just doing it wrong.
after all the only thing you do is TWIST AND PUSH, it really isent rocket science....

As you say everyone to their own and if it works for you then fine.

.....but I'd still, based in direct experience, highly recommend this cheap little tool if anyone is considering doing this job.

With the tool the job is virtually guaranteed to be easy but without it, judging by previous posts, many have struggled to the point of despair/anger (which is when things tend to get damaged) :(
 
stilo the best how old is your stilo?
just wondered if yours is fairly new that would explain the ease you had with the pistons.
I certaily could not have retracted either piston yesterday using pliers alone.
My stilo is an 02 plate with 104,000 miles and i think the rear discs were the originals judging by the discs condition:(

I am bewildered, are people really needing to put so much pressure to put the piston in?? i could wind and push in with one hand and the pliers, can it really be so hard?

It has been found by some members that the pistons have seized ..I had no problems when I did mine and used a pipe grips to turn the pistons and wind them in ..the knack is turning and pressing the same time for which I used a G clamp..

I'd actually be a bit concerned if you found it that easy :confused:

This comes up time and again on the Forum and I think you're the very first person to suggest that it's easy. Some people manage as Phil (PNL) has suggested but many have terrible trouble.

As I've said (lost track of how many times) it really IS easy with the proper tool.
 
I am presuming that everybody that does the pistons always takes the cap of the fluid resovior to reduce the air pressure and risk of damaging the rubber seals in the master clinder?
 
just tried my local fiat garage at WAKEFIELD west yorkshire he told i cud expect to wait up to 6 weeks for delivery of this tool! anybody in the wakefield area have this tool to borrow or buy?
 
Good tip is clamp the brake hose and open the bleed valve at the caliper so you're not fighting fluid gravity as well as the caliper piston. Otherwise you're pushing the fluid back up into the master cylinder and it's probably contaminated too after sitting in the caliper all its life
 
On the other hand, if you feel you want the tool order part 1870886000 this is the same tool but the little card you get inside will tell you it's for the Multipler
 
What you don't want to do is take the o/s/r caliper off the hub (still connectd to pipework), clamp it in a bench vice (not that the vice was connected to a bench) and try to wind the piston back in.

When this doesn't work what you really shouldn't do is put an eighteen inch long 1" ring spanner over the vice winder and give it death.

Caliper is now officially ruined. What a berk.
 
Thought I'd just add my experience, having changed my 04 JTD rear pads today. Took about 2 hours, being slow and careful (I'm not at full health right now), and wasn't especially problematic.

I used a simple cube tool turned by a 'tommy-bar' screwdriver, and a generic 6" quick clamp to apply the pressure. Also needed a lever to counter the torque, so occasionally three hands would've been nice. A bit more flexing and pulling on the hydraulic hose than I would've liked, too.

I think I'll probably order the special tool next time I'm in touch with a Fiat dealer. £10-15 is a good price (especially for an OEM item!) and even if I only use it a few times in the future it's a trivial cost for a simpler, quicker and neater job.
 
Thanks for all the posts guys. Tried to get the wind back tool locally in Mid Glam from main dealers and they wouldn't entertain the idea at all. Simonstone in Bristol was mentioned and they were very willing to order for me and post. Cost £15.23 + vat + postage.
Thanks

Well trying to do this job today (outside pad on OS down to the metal), of course the strip down was easy, just to lure me into a false sense of security of course!

Anyway, can't get the piston to turn, not even using a Laser rewind tool (not the best fit) which applies pressure at the same time as turning, of course this tool is only any use for the OS anyway (Halfrauds getting things wrong as usual) so that's going back, firstly as it doesn't really fit, and of course 'cause it will only do one side anyway.

Anyone with any tips on how to free it as it appears seized?

No matter, few taps with hammer, turn, few taps, turn and so on :)

Of course the handbrake isn't on lol, otherwise the pads and disc wouldn't even be off.

And of course the proper tool makes life easier, but it's only when you do the job you find you need one, many rears only need compressed like the front, and that is what I was expecting.

Anyway, like I said, I've sorted it :)
