dragging up an oldie here but whats to stop you using the focus st170 calipers and discs instead of using the mondeo calipers

i have the st170 discs and calipers on my sportka and the only modification i had to do was drill out the hubs for the bigger m12 mounting bolts and then bolt them on ????

why is it required to swap to a earlier servo and master cylinder

is the old master cylinder a different bore size for brakes if not shouldn't make any difference unless its a duff one

Apart from price lol, they are the same calipers yet you will pay a hefty ST "tax" if buying 170 ones

When I did this mod, the calipers cost me 20 quid.

I would advise against grinding down as quite a lot needs to come off plus because they run so close you probably will have problems with the cooling to the pads and heat issues. If you need to run 15 inch then run 280mm brakes , they fit under 15 inch wheels easiest fit are the ST150 brakes .
Hi, sorry for dragging this old post up but I just want to ensure that I am doing the right thing on this for obvious reasons. I do not want to be grinding having read the warnings in earlier posts

I am running the 15's (9spoke) but want to upgrade the breaks as the car is for tracking. what do I need to convert from start to finish. I can follow the how to do guide which is pretty awesome however I just want clarity on the parts/discs/callipers. Also can I use braided hoses?

Hi Puma_Sam

Which brakes are you wanting to fit, as this thread seems to have a mix of both!?

Hi,

The biggest/best/safest option to take on the track. I don't want to be grinding anything down as I don't feel comfortable doing so, nor do I wish to have the risk that is mentioned above about debris lodging in their or lack of clearance causing overheating.

I've just done the Mondeo 300mm conversion. I've noticed a few saying that the knuckles should be drilled with a 12.5mm drill.
I didn't have one and used a 12mm. The bolts slipped through just fine :)

ETA: The carrier bolts are 40mm. I had a fun time trying to get Ford to sell me some though. The guy was like, "I need the reg number, I won't sell them without one because I've had too many complaints about wrong parts"
I was like Mate, all mondeos have the same bolts and these are going on a Puma...
He wouldn't order them till he had spent 10 minutes checking the database...when he came back and said, these will be fine, all mondeos have the same.....

Referring back to the escort cosworth and mondeo cosworth style wheels different offset, would the correct wheel spacers sort the handling issue? Not sure I want to pay over a grand for escort ones of I can get mondeo ones for less than £200?

hi i have just ordered off ebay ford fiesta st rs turbo st200 300mm brake calipers with pads and am hoping they will bolt straight on. cost me £50 and some brand new focus 300mm 4 stud discs were £66.00 now on special at £22.00 so cost me £72.00 in total and some violet metallic brake caliper paint should be delivered by 31st aug i will let you know how it comes on great walkthrough how to do the mondeo mk3 system. i also have some mania racing 17" wheels on my puma

I too decided to carry out this conversion on my 2002 1700 puma. I can't recommend it enough! The old brakes I had were Brembo 258mm drilled and grooved. I've just installed 300mm ST170 drilled and grooved discs and the mondeo callipers, both mintex. My god they're good!! Only downside is vibration in the pedal! I suspect it's due to the ABS kicking in OR I didn't bore the calliper carrier holes out straight and there's maybe slight movement in the carrier so be careful anyone. Grinding the callipers and carriers is no fun at all! Still rubs when I'm cornering sometimes, so I would 100% suggest anyone looking to do this conversion should do it AFTER you have a set of 16" rims!! Otherwise it's a c*nt of a job :-D I wish I'd seen this guide before I did the works myself.

Looking to get the puma on to 15's, and it seems like we're going to struggle fitting them over our st170 brakes.

Looks like we may have to do down to fiesta st150 setup for the smaller disc. Would there be any issues with bolt hole sizes etc, considering they've probably been drilled out to fit st170? Hope that makes sense..

i think you'll need new knuckles :)

to drill bigger holes, is not a problem, to reduce a hole size is a problem. all depends on the size of the bolts

They're ~£200 each from ford parts! As far as I've read so far, it's only the 300mm conversion that requires drilling knuckles and not the 280mm. Is that right?

That's right. 280mm ST150's are a straight fit.

If you find some ST200 280mm brakes, they require the carrier holes drilled out to 12.5mm.

If the mondeo disc is replaced with the ST150 one, no spacers are needed. (Mondeo disc needs a 3mm spacer BEHIND the disc)

Ah interesting! So Mondeo st200 carriers and calipers, fiesta st150 discs?

Sounds like a right mix and match!

Fit 300mm Brakes how to guide

Post by trublustu » Mon Jan 02, 2017 2:06 am

but a perfect fit.

The piston on the Mondeo caliper is like a cannon barrel next to the Pumas.
The braking is immense,
Though it really needs a master cylinder swap to reduce extra pedal travel.

Also, The ST200 brakes are no different to any Mk1/2 V6 mondeo. (although there are two shapes of pad.)
All 280mm and good to upgrade with.
Best bit..,
Perfect with 15" wheels.

Dragging up an incredibly old post here... but need some info! :grin:

What is the best MC to upgrade to? I run the st200 calipers on st150 discs and there is a bit too much pedal travel for my liking.

Thanks in advance :D
