This Year’s Focus: Drums and Rotors
The 2026 Brake Safety Day placed special emphasis on drums and rotors. Inspectors identified 43 drum and rotor violations, of which 21 were out-of-service violations.
Ten U.S. jurisdictions conducted 349 inspections using a performance-based brake tester — a machine that assesses the braking performance of a vehicle. Federal regulations and CVSA’s North American Standard Out-of-Service Criteria require a minimum braking efficiency of 43.5%. Of those tested, 26 vehicles — 7.45% — failed to meet the minimum threshold and were placed out of service.
More than 90% of the inspections conducted — 3,643 — were North American Standard Level I Inspections, a thorough 37-step procedure that examines both driver operating requirements and vehicle mechanical fitness.
CVSA’s seven-day Brake Safety Week is scheduled for August 23-29, 2026, across North America.
