Kia Troubleshooting Questions? Ask a Mechanic
you don't say what model Kia this is but
I'd say the next thing to try is replacing the seals in the clutch master
if the reservoir fluid is dark then this is a sign that the seals are breaking up
If this doesn't help then next check the gear linkage for any worn bushes or pivots as any lost motion means reduced effort at the gearbox and replace as necessary. Ideally have your assistant move the gear lever with you watching the linkage and see if you can spot where there is any excessive play or lost motion.
If its a cable type linkage check along the cable lengths for any damage or signs of heavy wear / fretting, if you find any replace the cable. There may be some adjustment on the cable tension at the gearbox end (depending on the year) and the cable should be tensioned so there is a minimum of slack but not so its taught
there's a clutch master cylinder but it does share its reservoir with the brake cylinder
do you still need help?
