Hello!
I have to replace stub joint, but it's hard to get it in Poland (1988 S1).
1. Is it from sierra 2lt 4x4 drum only? Any other models?
2. Is it possible to convert it to disk breaks? Parts are easy to get.

Hi Marceli,
Yes, it is possible to convert to rear disc brakes, there are quite a few people on this forum that have done the conversion. It may involve some machining or replacing of the original hubs, but I'm not absolutely sure. Somebody wiser than I will be along shortly.
Check out Joe's helpful new brake wiki on here, also 'Useful Links' and owners blogs for further information.

What is the part that is worn on your S1? I'm assuming you mean the stub axle that fits in the rear hub? If this is the case, are you sure that it is not just worn bearings?
Or is it just the Lobro 100mm 25 spline CV joints that have worn? If so, J&R in Birmingham supply new kits at a very reasonable price. I'm sure there would be some way to get them sent to you in Poland. The CV's are retained on the driveshafts with circlips, not a difficult job to do.

Edit: I've just bumped mt old "DIVEshaft" thread. Hope that helps.smile

Aahh! That looks like it used to be a Left Hand threaded stub axle. Has someone stripped it trying to undo it the wrong way? frown

I'm not sure on the source for this one. Which Sierra models used this stub axle? Over to you learned guys out there.....

Unscrew was done in right way, but nut was glue with white loctite frown

What I know this type was used in 2lt 4x4 with drum breaks. That's the 1. question - any other sierra/scorpio?

PS Sorry for capital letters in topic - I'm not shouting wink

When you have replaced the stub-axle, this is what you need to do a rear disc conversion (with the 253mm solid discs).

http://www.ebay.co.uk/itm/ford-sierra-granada-4-st...

Are these what you are looking for?

Will these bolt onto the CV joint on drum-braked cars?

Is it plug&play conversion? Need I change something in a trailing arm?

As far as I am aware all the Sierra models with drum rear brakes shared the same stub axles. I don't know if other models (Granada, Capri etc) with drum rear brakes used the same stub axles.

The disc brake conversion is simple a bolt on job. There are two ways to do it. One, the simplest, is by replaceing the drum back plate with another back plate to take the calliper. This retains the original bearing carriers and stub axles though so not much use to you.

If your stub axle is borked then the 'swapping the carrier' method makes a bit of sense. You will need;

1. Bearing carriers inc bearings. Two versions are available one for 253mm discs, one for 273mm discs. The tabs are longer to move the calliper out.
2. Stub axles.
3. The bit the wheel bolts to. (these first three have been linked to by Joe above)
4. Callipers - there are two versions. If you go solid disc then you need the narrow mouth version. If you go vented disc then you need the wide mouth version. The same calliper can be used for either 253 or 273 discs (as it is located by the carrier). You need to match them to eith solid or vented discs.
5. New connection hoses. I'd recommend extending a single 'long' braided hose from the chassis connection at the end of the trailing arm. The calliper is metric but the chassis connection could be either metric or imperial depending on what TVR had to hand that day. May even be different side to side. You can by kits to make up your own hoses off evilbay quite readily.
6. Discs - vented or solid, 253 or 273mm - to suit the carriers and callipers.
7. Pads - same shape, size etc.. fit all the variations of size and vented etc.....

Really simple.

Unbolt everything - stub axle is done up tight.
Bolt on new stuff.

No need to remove trailing arm.

£25 inc. delivery to a UK address?


Got any friends in Redditch (near Birmingham)?


Guess it's immaterial now but can't see any type of "threadlock" would cause that damage? Could it have been damaged previously and sh#t loads of threadlock applied in some kind of bodge attempt at a repair?

Sorry to state the obvious; the "narrow mouth" caliper can be only used with either the 253mm or 273mm solid discs not the vented discs. For the vented discs, you need the "wide mouth" calipers and the Cosworth wheel bearing carriers. These carriers are harder to find and more expensive than the carriers for the solid discs.

Apart from undoing the brake pipe unions. It took me 3 sodding hours to get one undone, taking care not to damage anything.

I've just done job, see this post..........

You could also try to find a rear drum brake Scorpio or Granada rear stub axle. According to the Haynes manuals, these look similar to the Sierra ones.

To be clear.

Narrow mouth calliper to be used with solid discs, either 253 or 273mm.
Wide mouth calliper to be used with vented discs, either 253 or 273mm.

Fitting either 253mm discs needs the carriers with shorter tabs.
Fitting either 273mm discs needs the carriers with taller tabs.

It is off the shelf Ford kit from the Granada, Sierra and Sierra Cosworth. If the donor car of the carriers had 253mm discs then you will need to fit 253mm discs to the car. Likewise, if the donor car had 273mm discs etc.....

If converting to rear disc brakes, you will also need some specially made up handbrake cables.

Thank You all for replay.
1. I'll try to buy parts for conversion or even running Sierra 2ltr. I've found one for ~70Ł biggrin
2. or I'll contact You - Phillpot about original ones smile

Hand break cables is not a problem smile
