Abstract

In some implementations of the current subject matter, a braking system can include a first combination of braking components operable to slow or stop rotational motion of a first wheel of the multi-wheeled vehicle and a second combination of braking components operable to slow or stop rotational motion of a second wheel of the multi-wheeled vehicle. The first combination can include a first brake rotor and a first brake pad, and the first brake rotor can include a coating that imparts wear and corrosion resistant properties to the first brake rotor. The second combination can include a second brake rotor and a second brake pad, and the second brake rotor can lack the coating. Related systems, methods, articles of manufacture, and the like are disclosed.
