I have freshly removed from my 2003 Mondeo ST220, a pair of very good condition calipers painted blue, with Motorcraft pads and discs less than a few months old, done a few 1000 miles, pads are barely worn as are the discs.
Not your crappy siezed ebay jobbies, the car had done 59k. When i replaced the discs and pads a few months back they were stripped down, thoroughly cleaned and greased, i only use OE parts and the Motorcraft ones are way better than EBC/Mintex IMO, the discs show no signs of scoring, no overheating or warping (indicated by a blue tinge), i would have very high confidence in using them on another car with no problems.
I've looked on ebay and seen single calipers on their own and not even half as good condition for between £20-40.
These are a bolt on fit to a Mk2 Mondeo, the calipers can also be used on a Fiesta ST with ST170 discs (4 stud)
Collection only from Norwich, however i will deliver for you at a small fee (about £10) if you live in most parts of East Anglia, into NW Kent and Surrey.
