It's that time of year again. The Commercial Vehicle Safety Alliance (CVSA) has announced its annual Brake Safety Week, running from August 24-30, 2025. This is more than just a week-long blitz; it's a critical reminder for us all to prioritize brake safety. As mechanics, we are on the front lines of this effort, and it's our expertise that keeps the trucking industry—and everyone on the road—safe.
Why CVSA Brake Safety Week 2025 Matters
Every year, CVSA-certified inspectors in the U.S., Canada, and Mexico conduct comprehensive roadside inspections, with a special focus on brake systems. The results from past years are a wake-up call: brake-related violations are consistently the most common reason for commercial motor vehicles to be placed "out of service." That means a truck is grounded until repairs are made, leading to lost time, revenue, and serious safety risks.
This year's focus area is brake drums and rotors. This is no surprise—these components are crucial for a vehicle's braking efficiency and are subject to immense heat and wear. A cracked or broken drum or rotor can lead to a catastrophic failure, putting drivers and the public at serious risk.
Your Essential Checklist for Brake Safety Week
Brake Safety Week is a great opportunity to reinforce best practices and get your customers' fleets ready. Here’s a checklist to help you zero in on what inspectors will be looking for, with a special emphasis on drums and rotors.
1. The Drum and Rotor Deep Dive:
- Cracks and Damage:Â Look for cracks, especially on the friction surface of the rotor and the outer portion of the drum. Any missing pieces are an immediate red flag and an out-of-service violation. 
- Rust:Â Heavy rust across the entire friction surface of a rotor can indicate an inoperative brake. 
- Grooves:Â Deep grooves on a rotor suggest metal-to-metal contact, a clear sign of a worn-out brake pad. 
- Rotor Vents:Â If the center vents of a rotor are exposed, it's a sign of excessive wear, and the rotor needs to be replaced. 
- Broken or Missing Parts:Â Inspect all components of the brake system for any missing, loose, or damaged parts. 
2. Beyond the Drums and Rotors:
While the focus is on drums and rotors, a comprehensive inspection of the entire brake system is essential.
- Brake Linings and Pads:Â Check for cracks, contamination (oil or grease), and excessive wear. Ensure there is adequate lining thickness. 
- Air Leaks:Â With the air brake system charged, listen for any hissing sounds. Even a small leak can compromise braking performance. 
- Hoses and Chambers:Â Inspect for any cuts, bulges, or other signs of damage on hoses and brake chambers. 
- Brake Adjustment:Â Verify that slack adjusters are working correctly and the brakes are within the proper adjustment limits. Out-of-adjustment brakes are one of the most common violations. 
- ABS Lights:Â A lit Anti-lock Braking System (ABS) warning light is an automatic red flag for inspectors and can lead to an out-of-service citation. Make sure the system is functioning correctly. 
A Year-Round Commitment
CVSA Brake Safety Week 2025 is a powerful reminder, but our commitment to safety must be year-round. Encourage your customers to adopt a proactive approach to maintenance. Regular preventive maintenance programs, thorough pre-trip and post-trip inspections, and immediate attention to any reported issues are the keys to a safe and compliant fleet.
By being thorough and meticulous, we not only help our customers avoid costly violations and downtime but, most importantly, we contribute to a safer environment for everyone on the road. Let's make this Brake Safety Week a success, one safe brake system at a time.
