This article investigated how Japanese factorys develop their maintenance to reduce productions pauses. It increases productivity and quality, avoides products late delivery and satisfies customers needs. Besides TPM-Total Productive Maintenance, there is another maintenance system based on equipment operational conditions doing the maintenance in the exact moment of necessity that can be called MJIT-Maintenance by Just In Time. It avoids unnecessary maintenance based on the estimated life time that may conduct to realize maintenance before the real necessity or after broken. A qualitative research in brasilian factorys identified a high potential and need of a mainenance system similar to MJIT.
