As per title, im not sure what i need to do to make these fit, ive been told i need a spacer kit or something to make them line up?

Ive got the ST170 calipers with bolts and brackets and ive got the disks and pads..

Does anyone have any experience in fitting these? I need to fit them by ford fair so im desperate!

Thanks, Joe

You need only the ST170 discs mate, then MK3 Mondeo pads, calipers and 12mm spacers.

Joe91

Where can i get spacers? Also do i use the bolts and brackets off the st170 caliper or the ones of my erst calipers?

You need to drill out the hubs to take the bigger bolts, but the rest should just bolt on

Remove your callipers and trial fit the other brakes, remembering to use some wheel nuts to hold the disc firmly in place. And if every ting works you only need to sort out the brake pipes and bleed the buggers and job done

Joe91

Ok will my standard hoses fit on these st170 calipers?

dojj

iTrader: (3)

depends if the fittings are the same or not

they are either straight fit or tapper fit, i can't remember which buti had to change mine ont he fiesta

luke19790_3

if you have some 12mm metal, you could make your own

Joe91

Mmm just annoying as I was told these were a straight fit, I'm not one to do my own work on my car and there's no chance of getting it done by FF!

Joe, its not alot of work m8... Just drill the holes out and bolt the 12mm spacers and calipers on... Standard hoses fit - altho as you are upgrading it would be a good idea to swap them for braided hoses

Joe91

I can't get hold of any 12mm spacers though...

luke19790_3

Its just a flat piece of metal 12mm thick with two holes in.

why do you need to make a bracket when the ford stuff just bolts into place?

luke19790_3

Thinking about it I do have the brackets sitting in my garage.shame you're not closer

I don't remember using spacers on my ST170 conversion at all, are you sure they aren't Mondeo V6 brakes you have?

I might be way off the mark though as mine were done about 6 years ago.

12mm spacer are 100% needed or the calipers will not be central on the discs, in fact the discs probably wouldnt even go on! lol

Local engineering shop would make some ,thick dowl, big enough hole through the middle for bolt ,like a thick looking polo mint really ,thats what i had on mine

Joe91

What do the brackets do though? Are they the same as spacers or do i not need spacers with brackets? Sounds dumb but i dont have a clue!

Joe

luke19790_3

same thing

Joe91

Does it make any difference that im using ST170 calipers, St170 disks and pads? Does it still mean i need the spacers as i know alot of you have used mondeo discs pads and calipers etc because they are cheaper?

Joe

i simply fitted the stuff directly from the mondeo so it needed a little "fettling" to fit, but had i used the st170 discs they would have been a direct fit with no grindage required

also, i've been redrilling discs for years with no problems whatsoever as there is plenty of metal left between the studs, you just have to use a proper drill in a proper drill press and have a useable template to drill the holes in the correct places (i simply cut off the face of a 4 stud disc and then fitted it to a hub to centre it all up before drilling each hole AND i put bolts in to make sure the holes didn't move while i was drilling the next one)

the mondeo calipers are far more readily available and cost a fraction of the st stuff, but discs i would always advise to buy new, the ones i used had only done a few thousand miles and the calipers had been totaly overhauled so everything was tried and tested and working but if you were to get second hand stuff form the likes of ebay i would always recommened a rebuild just to be on the safe side

What's needed to fit ST170 300mm discs with the 4x4 calipers on an escort rs turbo?

kermitt

Mk3 mondeo calipers, pads and the correct spacer kit obviously.

Joe91

Mmm so can anyone answer the OP of anyone actually fitting ST170 calipers and discs? Not mondeo calipers etc, St170 calipers and 300mm discs..Going to fit them on friday with a mate but just worried incase we get stuck without things we need. Must be someone on here with experience!!

Thanks, Joe

I would guess the same as the mondeo stuff, its just the mondeo stuff is easier to get hold of and the calipers have a larger piston so more braking force!

If you have all the parts, mock fit it all up and see what needs modding to go where... It'll only be a case of spacing the caliper out by the correct amount (12mm with mondeo calipers - i dunno with the st170 ones) with a spacer plate or peices of thick wall steel tube.

I put st170 disc and calipers straight on. You only need the spacers with mk3 Mondeo calipers

Pridzz

Anyone find a link or pics for the so called spacers?

Zippy - on a mk4 escort?

marky_g

Digging up and old on here but what about calliper bolts? Do you just use standard Mondeo stuff will it be long enough with a 12 spacer?

dojj

good point

Jamie_EscortSport

Mark I got joes old 170 setup on mine now....they are normal m12 bolts with a med strength lock tight. I couldn't tell you the length off head but can measure. For you when I'm next up there ( if your in no rush)

marky_g

That would be brilliant mate

I've made my spacers now just need the bolts pmsl

Doodah

Awesome!
