A Maintainer is part of the depot maintenance team responsible for maintaining and improving fleet reliability. Maintainers perform routine inspections, diagnose reported conditions and make both scheduled and unscheduled repairs. Watch Maintainer Perry Yvel use specialized equipment to remove a 150-pound caliper from a bus. 8-year maintenance veteran Perry Yvel specializes in brake systems – a serious safety mechanical area needed to stop a bus that can weigh anywhere from 20 to 30 thousand tons. The bus operators report any unusual condition, and then it’s up to the maintainer to diagnose and make the repair in time for the bus to make its next scheduled route.
