They were probably held in by some dust or other crud. Don't flatten them... they have conformed to the commutator. A soak in alcohol or stronger solvent (lacquer thinner, Gumout, ect.) will remove any oil.
If the replacement spring(s) aren't of similar dimensions to the original (thicker, stiffer wire, for e.g.) then you should replace them. Only replace the brushes if they've worn down to short stubs.
