I just want to update this thread (a bit); I still haven't got around to purchasing new pads, but I have been looking around at websites of brake sellers, and I wanted to put the information here, in case it helps someone.
Regarding EBC: there are a number of sites selling EBC pads (and discs), and some of them give the impression that they are directly associated/owned by EBC. It seems that they are not.
Now, that may not seem important, but the important thing is that they do not always carry the full range of EBC pads, and just because some site doesn't have some particular pad, it doesn't mean that they don't exist.
Now, there is an EBC on-line catalogue, and you might want to use it, but be warned that it is a bit of a pain in a place that you wouldn't want a pain. The thing is slow, it crashes, it is difficult to read, and the index is wrong (currently you want something like page 122, irrespective of what the index says...and you can go directly to that page, but the syntax may be a bit obscure and the index sends you to ~roughly page 80, which is about the start of 'Fiat' not the end of 'Ford' - there is a lot of page turning in-between, and that's slow). Oh yes, and it crashes quite a lot, if you do tricky things like zooming to make the text actually readable.
This isn't exactly glorious, but you can live with it because you can get the info from seller websites...except that sometimes, you can't. Camskill, who are nice people and have decent prices, only list the part numbers and prices, so don't let you look up the part number that is applicable for your car.
Just before this turns into an EBC love fest, I just want to comment on the offerings from some other manufacturers:
Pagid make some very good pads (eg for racing Porsches), so they clearly know what they are doing, but I just can't find out what they are offering for the Mondeo. You can find a pad, but if is just their equivalent of a standard pad, then there isn't that much point if you are looking for an upgrade.
Similar comments apply to Mintex (part of same TMD group). They make different pads, and something is available for the Mondeo, but it isn't clear whether it is just a standard specification pad made by them, or something more performance orientated. Given that they are the same group, these may even be the same pads as the Pagid ones, with a different name on them, or made on the same production line, I just don't know (Textar and Don are other members of this group, and you'll find Textar pads around, too, for example here, where you'll also find some others (I'm just told to avoid the Eicher ones, as they are bad in some way, but I don't know)).
I'm sure I saw someone offering Brembo pads, but I can't find that now. Again, I know Brembo make some good pads (either as Brembo or AP, their associated company), but I just couldn't figure out which pads these were from their range. And their catalogue doesn't help - it is several years old, and doesn't list anything for the Mondy.
Now off to research disks!
(Oh, by the way, I had been told, several times, that 'all MkIV Mondeos use the same brake pads'; the EBC catalogue lists a different reference number for the parts for a 2.5 T than for the rest of the range. So, like mick85, I now think a more correct statement would be 'all MkIV Mondeos, except the 2.5 T, use the same brake pads')
