have issues,” he said. Repeated washings and the application of anti-corrosion protection appear to be the key to defeating the cruelty of rust, as reinforced by Jeff Moody, director of trans- portation for Tomah Area School District in Wisconsin. The Badger State is infamous for the severity of its winter months. “Frequent washing is the key. Corrosion protection helps, but a bus has so many open areas, nooks and crannies, etc. You cannot seal in them enough to prevent corrosion,” he said. More and more, the industry is seeing vehicle components coated with corro- sion protection to extend life and reduce maintenance costs. Such is the case with brakes. Johnathan Capps, vice president of engineering for Webb Wheel, said a frequent concern with rust in brakes deals with hydraulic rotors, especially those subject to high concentrations of magnesium chloride, or road salt.
“They are having corrosion build up along ABS teeth, causing signal faults and prompting replacement before usable life is up,” he said. “We’ve also found some rotors being replaced due to delamination—essentially the surface starts to rust and flake away. There are no replacement guidelines for this, it just is what it is and requires replacement.” Many component suppliers spray a coating of zinc or other corrosive-resis- tant material to parts to ward off rust, but the layer can wear away over time due to heat, as braking temperatures can exceed 350 degrees. Webb Wheel, Capps added, goes a step further by adding a metallurgic heating process to its products to provided heightened corrosion protection that he said can double product life.
a later date,” Sterling said. “If repair is highly specialized and mechanics do not have the knowledge, tools or time for the repair, then bus is sent out. All warranty and recall work is sent out.” Lawrence credited the durability of
the Fairport fleet to the proficiency of the mechanics that work on the individual buses, as it’s considered a “win-win for both parties if our team is ahead on their maintenance and repair schedules.” “It is critical that technicians keep up with the preventative maintenance
