A reminder that proper brake maintenance is critical to keeping our roads safe.

Recently, a box truck was parked on a hill in Chappaqua, Westchester County, while the driver made a delivery. After setting the parking brake and exiting the vehicle, the truck rolled forward and struck another vehicle.

A subsequent inspection conducted by members of the New York State Police Troop K Commercial Vehicle Enforcement Unit (CVEU) determined that a dislodged roller pin (a critical brake system component) allowed the brake actuator rod to separate from the slack adjuster, preventing one of the truck’s brakes from functioning properly. The inspection also revealed that the truck’s rear brakes were significantly out of adjustment, leaving the vehicle with the equivalent of only 1.5 properly functioning brakes out of four. Due to these critical safety violations, the vehicle was immediately placed out of service.

Incidents like this serve as an important reminder that routine maintenance and thorough brake inspections are essential. Identifying worn or damaged components and correcting brake adjustment issues before they result in a failure helps prevent crashes and protect everyone who shares our roadways.
