Technical Rear brake caliper wind back tool

Hi Argo
Yes it's a bitch trying to push AND turn AND hold the caliper at the same time. There's nothing to push against so you waste half your efforts and can easily do some damage.
This is the point really, we can probably make do with something make shift but it's very time consuming and frustrating. Even universal tools like the cube have their problems as you're finding, but something specifically designed for the Stilo which will do the job in minutes is what I'm after.

With something already doing the pushing for you, you can get on with the turning and, whilst it's doing the pushing, there's no chance of the piston falling out:)
 
There will always be people who "managed with two teaspoons, a mole wrench and a bicycle pump" Good for them. I do too for those odd ball tasks

But this is an increasingly common task on Stilos, more people want to upgrade dics and pads and mileages are getting to rear pads changing time

I intend to make a tool that is specifically for the Stilo which will fit properly, do the job in not time, doesn't slip off and where the user will have hands that a mother could love at the end of the process. Bee dee beep -job done is the plan rather than emerging bloodstained and battleweary
 
Well look what I've found!

Checked it out and it costs £11.46 from Fiat, available 2 days special order

Well that'll do me, Jimmy! Remarkably similar to what I had planned. No sense re inventing the wheel. Problem solved. Case closed:)

Absolutely amazing Decks (y)

Checked with my local main dealer and they want £15.25 + VAT

What's your source ?

Pity in a way as I had a good work-out with the Stilo the other day and was kinda looking forward to a rematch now I've got my muscles bulging :D

Mmmmmmm wonder if boss will buy one of them for us :chin:
 
As regards the Fiat Rear brake caliper wind back tool.
Anybody know what Thread Pitch and Diameter the Set Screws are ?

Also the Dia of the Pins/ Pin Pitch Circle Diameter of the Adapter that Fits into the Piston.

You still thinking of making one then :confused:
 
Hi Decks

I am considering making a tool with possibility of selling on ebay.

Might buy one as you suggested so I can measure screwthreads etc My main concern as you will appreciate is to ensure as the Setscrew is turned it will move axially at the same rate as the piston .

Depends on market for the tool though

I would have thought that Fiat would have thought about this [Axial angle of threads] when they manufactured the tool Tim WOULDNT THEY :chin:
 
The way I understand it is that it's a pretty crude "thread" on the piston, a bit like a drinks bottle or a jam jar. The piston doesn't rotate around the thread when it's in operation, it just clonks over the threads like a ratchet, pushed forward by the hydraulics. The thread acts like a ratchet to stop it backing off too far from the disc (in the case of a warped disc perhaps) as the brakes have also to be used as a handbrake and the handbrake mechanism doesn't move the pads much so the pads need to be kept close to the disc.

Because of this crudeness then, to retract the piston, it really just needs something to provide the push and something else to provide the turn. To "force" it in using a set screw thread would be counterproductive I think and more liable to produce jams (even though the Fiat tool looks like it does it this way). I think it's better if it has some slackness in the system so it can find its own way by persuasion rather than forcing it along a set path

Thanks for info Decks
I think it should be quite easy to manufacture this tool.

I`ll order one from Fiat, measure thread pitch etc and from there see about pricing up LH Taps etc .

Be a darn site easier to buy a load from Fiat and then mark them up to £25 wouldn't it :rolleyes:

(hopefully you wont be trying to sell to Forum members :) )

While you're about it you could fit new locking screws as well ;)

its not the angle I have asked about its the Pitch
 
It is so easy to do, i changed my rear pads only 4 days ago, Just use a pair of long nosed pliers and turn, i changed my pads in 20 mins flat, including jacking up and taking of wheels, so easy, no special tools neaded.

Dont forget the copper greese.
Dont forget to line the calipers cut outs with the pins on the back of the pads.

Even my Girlfriend could do it, and she is a WOMEN :eek::eek::eek::eek:

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 :))
