Hi,

I do have a super seven built in Germany. As I want to replace the rear wheel/brake system I wonder what type of Sierra system I have.
I do have an 253mm vented disc. 4x108mm wheel screws, The manufacturer told me, I have to look for Sierra, vented disc systems with ABS.

I have read several posts in here but it is unclear for me from from which type of Sierra my system is.
Cossworth 2WD/4WD, Standard, 4x4....
Ist there any chance to find out on the given information?

Thanks for your help

 

Any non-Cosworth Sierra will do.

best option is post Jan 1990 2.0 DOHC or V6 as almost all of them as standard by then

Are they definitely 253mm, not 273mm though as the ears on the carrier look quite tall in that picture?

 

Hi,

thanks for the hint.
Yes, I took some measures....

The interesting thing is, that it seems that most likely non-Cossworts hub may fit, but I did found only for solid disc. It seems to be different because the vented is 20mm and the solid 10mm thick. Also the size of 253mm seems not to fit to this set-up in a standard Sierra.

Could it be a mix of different female hub, carrier and disc? (not sure about the correct wording, how do you name pos 1 and 2 in the above picture?)

 

I will try to check my pictures of my one over the weekend but the hub carrier looks like a Cosworth one to me. If that is the case, then a 273mm rear disc is what you need. If you can measure the gap in the caliper carrier (where the disc sits inside and the pads sit on) to see if it is around 13mm or 24mm that would help as that would determine if solid or vented discs.

the one real differences are the hub carriers and the brake caliper carriers between models and solid or vented calipers

 

I’m not sure what you want to replace, but it seems like a setup from a Cosworth that uses 273 mm discs, as these have taller hub carriers to space out the brake calipers. Whether you should use vented or solid discs only depends on the width of the calipers and caliper carriers.

 

253mm vented discs are from a 95-98 ford scorpio, not a sierra. i've got them fitted to the back of my sierra

Hi,

so, what I want to replace is the brake carrier and female hub in the above shown picture no. 1 and 2.

Scorpio, aha. I see. Well then I need to find out the part numbers of the above two pieces. Funny, that Scorpio seems in this cae different to Sierra.
So I need tolook for Scorpio 4x4 or 4x4 Scorpio Cossworth?

 

if those are the parts you want to replace, then you should be able to use any sierra rear hubs with 253mm discs (not cosworth) or any ford scorpio (95-98) with 253mm rear discs

 

...but you said these where not from Sierra...I am confused now.
Does the Sierra has as well 253mm vented disc brakes (i.e. in 4x4 version)?

 

4 stud on a Scorpio ?

I'd have thought any Granada related stuff was 5 ? easily drilled to 4 though. For such a light car...hard to imagine a need for vented, and it also requires suitable calipers which are getting harder to find unless using aftermarket

Does the OP have any parts at all ?

searching online catalogues you can find stuff

Some Sierras may have sued small 253mm solid discs, 4 stud.

Pretty sure that any vented discs on a Sierra were 273mm. ie 4x4 cosworth. ( 2wd cosworth solid 273mm )

Not sure what a basic say 2.0i 4x4 non cosworth sierra used.


edit..
page 89 gives some listings. 253mm discs, 260mm discs. 4x4 even on lowly models vented.

So what I read is: Definitively Cossworth will not fit.
If it is Sierra or Scorpio, is still open, when we talk about 253mm vented and 4x108mm.

Does anyone have a parts catalogue of Sierra and Scorpio? On 7zap there are no pictures for these parts for Scorpio. And those for Sierra show only drum based....

I could go for solid disk, but this requires as well new brake calipers. And, it is unclear if this would fit to the spline I have...

 

For the bearing/hub carrier you need one from a car with 253 mm discs, vented or solid doesn't matter. All Sierra's, Granada mk3 (1986-1994) and Scorpio (1994-1998) have those, except for the Sierra Cosworth and Granada 24v (Cosworth) and Scorpio 24v (Cosworth).

For the 4 stud hub you need one from a Sierra with rear disc brakes or one from a Scorpio (1994-1998). For this part it doesn't matter which engine type it is. The Granada mk3 (1986-1994) uses 5 stud, so cannot be used.

 

Thanks for the clarification.

I had contact to a commercial seller on ebay uk. He stated: "solid discs have a slightly different offset with the mounting point to the vented style caliper which has another different offset"....

 

You can use this link to find and compare part numbers: https://www.catcar.info/ford/?lang=en

The part number for the bearing carrier for the 253 mm discs is 6146626
The part number for the bearing carrier for the 273 mm discs is 1637603

The part number for the 4 stud hub is 6156880

I'm not sure what that eBay seller is saying, but I'm 100% sure on the above.

 

Great, thanks a lot!

Final question. Thee studs are all the same then? Sierra, regardless of engine or Cossworth....

 

Yes, the studs are all the same. You can easily replace the studs as well. You can simply knock them out with a big hammer.

 

Like the catalogue links I already posted ?

 

@Mark Sierra: sorry, I meant the stud hiubs with my question...

@StevieTurbo: no, you are right. In your link it was available. Thanks.

 

I have no clue what you mean with stud hubs. I meant the wheel studs that stick out of the hub that you bolt the wheel to.

 

OK.

You wrote above: "For the 4 stud hub you need one from a Sierra with rear disc brakes or one from a Scorpio (1994-1998). For this part it doesn't matter which engine type it is. The Granada mk3 (1986-1994) uses 5 stud, so cannot be used"

My question to this is: These "4 stud hubs" are all the same then? Sierra, regardless of engine, OK but with Cossworth "4 stud hubs" neither?

Thanks

 

More to the point.

Exactly what parts do you have now, and what brakes do you want ?

 

Yes, as long as the car has rear disc brakes the 4 stud hubs are the same, so including the Cosworth. Hubs for cars with drum brakes are different.

 

From the pictures I'd say those are 4 stud hubs with carriers from a Sierra/Scorpio with 253 mm brake discs.

The big question is indeed what he wants to change and why.

 

I want to replace the carrier hub, the stud carrier hub and the wheel bearings.
All parts are more than 24 years old. The wheel bearing are faulty most like the carrier hub inside as well.
The threads of the studs are partly broken and I cannot hammer those out because the pre-owner welded them to the carrier.

So more or less a restoration.

 

I'd doubt they're welded so much they could not be ground off the rear and new studs pressed in to the driving flange

Bearings, easy, just replace them.

Unless the bearing has failed massively, the carrier would be fine.

Really though....sounds like you would be easier buying both rear arms entirely off whatever vehicle you decide it's brakes fit you best, and diameter there will depend on what room you have inside the wheels

You haven't stated whether you actually have any discs or calipers yet either ?

 

or here is a seller selling xr4x4 hubs....big money, then just buy discs/calipers to suit.

https://www.ebay.co.uk/itm/264920671...Condition=3000

 

Yes, I do have 253mm vented disc and and suitable calipers, which work fine.

With the ebay offer, I can not be sure if they fit to my drive shaft / spline. I heard there are different versions as well.

Raer arm completely exchange I thought as well about. Take a look to the picture (right side of the car). I do have no clue from which car this arm is from.....do you?

 

presumably the upright is a custom piece for whoever makes your vehicle/chassis.

I would be very surprsied if all small shaft/diff cars did not use the same spline on the driving flange. ie 7.0" diff cars.

Still say just replace your bearings and studs and go from there. At least thatg way you know the parts are correct....as you already have them

 

OK. Yes, seems to be done practically and take everything off. And start from there.

Thanks a lot.

 

I gave you the part numbers before. You can check the online Ford part number catalogue yourself, there are no different versions than what I stated before. All cars use the same splines.

 

OK, You are right. Thanks.
