Squeaky breaks

[willd58]

My cars breaks have gotten very squeaky, i mean, theres allways been a bit, but just after getting home tonight its gotten allmost unbearable, whats the common factors in this?

Cars a Fiesta Zetec S mk 5 i think, its got front disks and read drums apparently.

how much should a garage charge for this kind of thing? i dont have a drive and have no clue when it comes to think kind of thing, so doing it myself isnt really an option.
