if you want to replace the master you can.. or get a rebuild, but if its leaking from there you should ba able to see it no probelem. the masters on the jeeps are fairly decent as long as you keep it full and contaminent free i think 14 years is just fine. but the slave on the other hand... those usually fail alot, 14 years is a long life time for one of those on a jeep, i'd almost consider the jeep slave/throwout a manufacture defect worthy of a recall.
