hi looking for some help my 3ltr capri has had a rear disc converstion done have managed to sus out that it is siera callipers that has been used but cant identiy which discs have been used the wheels i have on the car are 13" rs alloys dose anyone no which discs are used when running 13" wheels thanks.

 

you will prob have more luck if you could measure the diameter and thickness of the disk and a pic may help too


Ps welcome to pf mate

 

hi mate discs are 10mm thick

 

What diameter disc and what off set(height), it could be a front disc from a lower powered ford used on the rear of the capri.
If you put a disc on a table then put the depth rod of a vernier through a bolt hole and measure to the outside hub face from the table/disc surface this is the easiest way, there's not many discs will go under 13" wheels and be ok with the diameter suitable for the cossie/sierra rear caliper.
The consul classic for example used 241 x 10mm discs with a 28mm height, but your height looks a lot more, the 80-90 escort 1.1 used a 240mm with 58mm height that looks more like it.
I can tell you 100% with the other dimensions though.

dont think a can get disc of without breaking it its stuck solid the guy a bought the capri from said the breaking on the rear was from a mondeo which it defo isnt

 

found this on ebay which suggest they could be peugeot discs

 

it's bigger than a normal sierra rear disc

 

i have sierra rear discs there they dont fit there to big

 

It isn't a pug 405 rear disc, there 247mm but height is 34mm, and those are much higher, just measure then from the wheel face to the disc face(outer), I can simply add the disc width to find the height.
They could well be from a pug, but there's also at least 5 other makes they could come from, 4x108 was very popular years ago for a lot more than just ford.
Without the measurement of the hub to disc face it's a guess at best, just put the vernier on the edge of the disc/wheel face and do the depth measurement to the disc surface, adding 10mm will give the height.
I note the larger centre bore hole, which could well suggest it came from something other than ford ?
NEED HEIGHT AND DIAMETER, some sierras had a 253mm solid rear disc for example, rather than 273mm solid of the 2wd cossie.

there are 2 brake holes for securing stuff, so that's anotehr clue, possibly german in origin?

 

hi just measusred 23mm + 10 = 33mm could be 34mm all in eyesight not that great lol

34mm, piccie makes it look much more, do you have the diameter ?, what sierra discs do you have so I know what size these discs are smaller than ?
A few contenders, fiesta 2.0 253mm 34mm height 11mm thick 2004 on,(98-2005 focus/granny/scorp etc etc also), pug 106, 91-2001 1.0 is 247mm 34mm height, 10mm wide, these are the front discs for this car, I'd bet they were this disc, but need diameter!!

Caprisport used to do (and perhaps still do) a conversion to fit behind 13" wheels. It used modified peugeot discs.

 

think the diameter is 246 cant get it to acurate with disc still on car the sierra disc is 251 hight 34 the, hub section of the siera disc is to large a diameter it would stop the pad seating properly hub part is 165 diameter

 

fiesta mk3 1.1/1.3 front disc i belive with sierra caliper. same set up i had on my old 2.8.

 

89-97 festa 1.1/1.3 is 240dia 43high 10wide,

Pug 1.0 91-2001 had an alternate size of 247 34 10, most pug centres tend to be slightly larger than fords of the capris age, though there are exceptions, is that a gap I see between the centre bore of the disc and the hub/bearing part ?, if so I think you have the alternate pug size, EBC disc D115, is the part number.

yep it is a gap where as the siera disc there is no gap
will check out the part number u gave me bloody thing gettin on ma nerves now lol

 

re your pm, I wouldn't worry about 1mm difference in the 405 rear versus 106 front disc, won't make any difference in real terms, that's only 0.5mm, 20 thou larger, seen at caliper so either will fit perfectly.

thats great prob solved will get discs ordered now thanks for your help cheers miller.

 

No probs matey, seems to be a week brakes this week, that's what I've been doing today!!
