HELP!!!!!!!!!!!!!!!!!!

just replaced whole hanbrake cable from lever to shoes including the equaliser but it wont take up the slack and i had to wind in the adjusters all the way ,surely the idea of new cables should mean less adjustment, i have spoke to several people in variouis motor factors and people from kia and they assure me only one cable fits the reg number i gave them. only on looking at new cables against old cables i see new cables are longer than the old ones? could these old cables be off an older mark. Somebody please help this is driving me insane as the missus needs her car back
