are fiesta caliper carriers the same as sierra carrier calipers ??

I don't think so - but which sierra and which fiesta ?

well i need some sierra caliper carriers for single pot 60mm sierra calipers (the standard sierra caliper from xr4x4 2.9 dohc etc from 90's) and they're like rocking horse poo but there are listings on ebay of fiesta ones such as this which suggest they are the same..


FORD FIESTA MK1/2/ SIERRA MK1/2/3? BRAKE CALIPER GENUINE FORD

wondered if they ARE the same

Well that listing is just BS

Mk1/2 fiesta calipers I've had are nothing like that and there is no such thing as a mk3 sierra.....


The 60mm piston calipers for the 260mm discs are on the XR4x4 as you say but that includes the V6 and SOHC versions too, also the XR4i, any normal sierra with ABS and any non-cossie with 4x4

They are also the same as the mk3 Granada ones (not cossie) and one version of the RS turbo escort



And I've got a 60mm slightly crusty pair of calipers with carriers going spare, but I wont be able to get them out for a while I'm afraid....

thanks for the detailed reply.

to be absolutely precise... what i want is caliper carriers that have the same slider pin spacing as those on the 60mm sierra calipers.

I'm fitting 300mm focus discs to xr4x4 hubs and will need to make extension brackets for the carrier to hub. this means that, whilst the carriers must have the same spacing for the slider pins that the sierra 60mm caliper uses, they need not have have the same hole spacing for the hub mount bolts.

does that make my choices any easier?

As far as i know the carriers only fit the one type of caliper and you may need to modify them a little to fit the bigger disc even then

Dax did a similar with the smaller 54mm calipers over the 278mm cossie 4x4 discs


Would it be easier to fit the focus st170 calipers instead ? That way the pads would cover the full are of the disc too

funny you should mention Dax ...

my car is a dax rush quadra and is currently running 324mm rs focus discs. to make them fit i had to grind the caliper carriers slighty as the focus disc is 28mm thick compared to the 24mm std sierra or cosworth ones.

i want to run the 300mm st170 discs however and they are 24mm thick and that means that my grinding of the carriers has resulted in a situation whereby revertion to 24mm discs means the pads might drop out when they get worn!! for that reason i want replacement caliper carriers.

incidentally, the brakes work ok just as they are except that when pads get replaced i need to shave 2mm off each one on the lathe prior to fitting so they can fit with the thicker disc. also had to grind the caliper to allow a greater diameter disc

i think that different cars (or more acurately, different disk diameters) would have been supplied with different carriers so that the correct radius could be established but that doesnt matter to me as i need to make up new spacer plates in any case


Dax supplied my car with 60mm piston calipers

There is one single pot caliper that's bigger than the xr4x4 one - the one that was used on the cossie 4x4's with 278mm discs

Or there is the 2wd cossie 4pot one, but they are heavy...
