i read somewhere that all i need to do this are any mk3 mondeo front calipers and new disks and pads.
does anyone know if this is correct? or do i need any brackets or new hoses etc??

thanks guys!

i think that is right

you can get calipers off ebay for 40 quid the pair thane front and rear grooved mintex discks and pads for 190quid! bargain i think!

does anyone know what model and year the caliper come from?? or is it any mk3 mondeo? or does engine size matter??

I'm not sure but go to a scrappy with a tape measure

ive seen some cosworth 4 pot calipers on ebay wonder if these will fit..

any mk3 mondeo caliper will work mate. engine size does not matter. I got mines off a st220 mondeo, low millage

i was speaking to my dad today (he is a mechanical engineer and has over 20 yearsof rallying under his belt building his own cars) and he said tha the problem is with upgrading the calipers is unless you adjust the master cylinders correctly they will be out of balance! i.e coz the piston is bigger you will need more fluid and more presure to brake tha same amount as with a smaller one, so you will be braking a lot harder on the rear brakes already.
he also said it will screw up the abs as it works via a pump which will be preset for a ceratin resure and to release a cetain amount which wont be the same with bigger calipers.
he said unless you upgrade master cylinders etc you will unbalabce the car.

so im just gunna put better pads and disks!

this is true on older cars but with newer ones like the fiesta st this wont make any diffrence as alot off parts like the master cylinder will be shared with many other ford models.

just fit upgrade discs and pads and u see the differente and its much cheaper than fitting bigger dics and for road use u don't really need this

Ive been readin up on this and i found out wat needs to be done but just wondering has any 1 done this to there st and does it make much of a difference.

After racing a vauxhall this morning and over taking him and realising theres a roundabout infront of me and failing to stop (while praying to god i dont die) i shall be upgrading the 300mm brakes :P and ill do the rears too lol.

Any one know if the mintex pads supplyed with it are squeeking like some one said above?

I have mintex pads on my RS and they dont make any strange noises, if they do use some copperslip on the back of the pad, works for me.
