2025 Brake Safety Week results

Top 3 violations of Brake Safety Week 2025

Most out-of-service (OOS) violations were issued for stand-alone brake violations:

1. Failing the 20 percent defective brakes criterion (defective brakes equal more than 20 percent of service brakes) (1,199)
2. “Other” OOS brake violations (375)
3. Brake hoses/tubes (306)

A vehicle placed OOS is restricted from travel until all the OOS violations are corrected.

Brake Safety focus – Drum and rotor violations

In addition to OOS violations, inspectors also focused on drum and rotor violations.

This year, inspectors checked for violations across:

• Air disk brakes (72)
• S-cam brakes (32)
• Hydraulics (9)

Within each category, inspectors looked for broken rotors, rusted rotors, metal-to-metal issues, and broken drums.

Inspectors found 113 drum and rotor violations, 39 of which placed vehicles out of service.
