From August 24 through August 30, law enforcement officers across the United States, Canada, and Mexico will take part in the Commercial Vehicle Safety Alliance’s (CVSA) Brake Safety Week. This week-long initiative concentrates specifically on commercial vehicle brake systems to help keep roads safer.

During this period, certified CVSA inspectors will carry out routine inspections targeting brake components, with a special focus on brake drums and rotors, which are the central theme of this year’s safety emphasis.

Damaged or broken brake drums and rotors can seriously reduce braking efficiency. Loose fragments may fall off while the vehicle is moving, posing risks not only to the truck but also to other motorists, potentially causing accidents or injuries.

Any commercial motor vehicle found with brake-related violations or other critical out-of-service issues will be taken off the road until repairs are completed.

Last year’s data shows the importance of these inspections. Out of 16,725 commercial vehicle checks conducted during Brake Safety Week, 2,149 vehicles were cited for brake-related out-of-service violations,  an out-of-service rate of 12.8%.

In the U.S. alone, inspectors performed 14,692 inspections last year and found 1,900 brake-related violations that required vehicles to be removed from service, marking a 12.9% out-of-service rate.

What is Brake Safety Day?

Brake Safety Day is an unannounced event under CVSA’s Operation Airbrake program. During this initiative, certified inspectors carry out routine roadside inspections with a special focus on brake systems and components. This includes identifying violations and collecting brake-related data.

According to CVSA, the inspections were conducted on April 22, and 91.3% of the vehicles inspected (4,171) were free of brake-related out-of-service violations. However, 8.7% (398 vehicles) presented critical brake issues serious enough to require immediate out-of-service orders.

Key Focus Areas and Findings

This year, inspectors emphasized vehicle drums and rotors. Out of all inspected vehicles, 32 (8%) were found with drum/rotor violations, 14 of which resulted in out-of-service orders. CVSA emphasized, “Brake drum and rotor issues may affect a commercial motor vehicle’s brake efficiency and result in violations or out-of-service conditions that may affect a motor carrier’s safety rating. Furthermore, broken pieces of drums or rotors may dislodge and damage other vehicles, causing injuries or fatalities.”

Additional brake-related findings included:

• Defective brakes: 237 vehicles (59.5%) had 20% or more of their brakes in out-of-service condition.
• Brake hose/tubing violations: 77 vehicles were cited for these issues.
• Steering axle violations: 48 vehicles were found with out-of-service steering axle problems.
• Air loss rate test failures: 38 vehicles failed this vital test.
• Other brake-related issues: 112 vehicles faced violations, including worn hoses, inoperative warning devices, hydraulic fluid leaks, and more.

Performance-Based Brake Testing (PBBT)

For added inspection precision, nine U.S. jurisdictions used Performance-Based Brake Testers (PBBTs). A PBBT evaluates a vehicle’s braking performance, and federal regulations mandate a minimum braking efficiency of 43.5%. Out of 100 vehicles tested via PBBT, 8% failed to meet this standard and were placed out of service.

Ongoing Brake Safety Efforts

Brake Safety Day is a part of CVSA’s broader Operation Airbrake program aimed at enhancing commercial vehicle brake safety across North America. The initiative will continue with the upcoming Brake Safety Week, scheduled for August 24–30.

Maintaining commercial vehicle brake systems is not only crucial for regulatory compliance but also essential for ensuring road safety and preventing potentially catastrophic accidents. For commercial drivers and fleet operators, these efforts highlight the importance of regular maintenance and inspections.

Vehicles passing Level I or Level V inspections without critical violations may earn a CVSA decal valid for three months.

During the 2024 International Roadcheck, tire issues and brake-related violations accounted for over 50% of all Out-of-Service (OOS) violations.

“According to CVSA, nearly one in four commercial vehicles inspected during last year’s event was placed out of service,” said TJ Thomas, director of marketing and customer solutions for Bendix. “With brake systems, tires and other aspects of vehicles, attention to detail, consistent training and regular maintenance can deliver real-world safety and compliance improvements.”

To help drivers, technicians, and fleets prepare for Roadcheck 2025, Bendix offers key insights and best practices.

The Vital Role of Brake Maintenance in Safety

Brake-related violations remained the leading cause of OOS orders in 2024. CVSA reported that defective service brakes accounted for 25% of vehicle violations, while additional brake system-related issues comprised another 18%.

“Brake systems are the backbone of any truck’s safety suite,” said Rick Conklin, director of wheel-end engineering at Bendix. “Not only do they bring vehicles to a stop, but they also enable advanced driver assistance systems (ADAS), like full-stability control and collision mitigation, to function optimally. If brakes underperform, the entire safety architecture is compromised.”

To prioritize brake safety, Bendix recommends daily walkarounds and in-shop inspections.

During walkarounds, look out for:

• Damaged air chambers
• Misaligned slack adjusters
• Extended pushrods

Technicians should perform these shop inspections:

• Measure brake chamber stroke and check adjustments.
• Conduct brake applications above 80 psi to identify air leaks.
• Inspect friction components for cracks, wear, or contamination.
• Evaluate drums and rotors for heat spots or damage.

“Brake performance starts with the right friction components,” Conklin added. “Using OEM-specified parts and meeting Reduced Stopping Distance (RSD) standards ensures braking balance. Replacing brake pads or shoes in matched axle sets is critical to maintaining performance.”

Conklin also emphasized the advantages of air disc brakes, highlighting their ease of inspection, reduced risk of out-of-adjustment violations, and exceptional performance benefits.

Tire Maintenance Tips for Roadcheck Compliance

Tires are another primary focus for Roadcheck 2025, with inspections including tread depth, inflation levels, sidewall integrity, and repair quality checks. Proper tire health reduces the risk of roadside incidents and unnecessary costs.

Over 20% of vehicle violations during the 2024 Roadcheck were tire-related, with underinflation being a common cause of failures.

“Underinflated tires are more than a wear issue – they’re a potential safety liability, increasing the chance of sudden failure due to excessive heat buildup,” said Brian Screeton, manager of technical training and service at Bendix. “With today’s technology, there’s no reason not to monitor the pressure in real-time and catch problems before they turn into emergencies.”

Bendix suggests using tire pressure monitoring systems (TPMS), like SmarTire and Trailer-Link, which continuously monitor tire pressure and temperature inside the cab.

“TPMS solutions do more than alert you to inflation issues,” Screeton said. “They can identify brake drag, which causes dangerous pressure and heat buildup at the wheel end.”

Tire maintenance recommendations include:

• Checking tread depth to meet legal standards.
• Inspecting sidewalls for damage or embedded objects.
• Ensuring dual tires are properly matched and inflated.
• Conducting routine rotations and alignments.

Tractor Protection Systems (TPS): A Step Not to Overlook

Although not a specific focus category for 2025, Tractor Protection Systems (TPS) remain crucial for trailer safety during unexpected disconnections. Over 560 TPS violations were reported during the 2024 Roadcheck.

“A well-functioning TPS can mean the difference between a safe stop and a runaway trailer,” Screeton stated.

Screeton outlined a straightforward method for verifying TPS operation:

1. Start the engine and allow the air system to pressurize fully.
2. Shut off the engine and disconnect the glad hands from the trailer.
3. Push in the red trailer-supply valve on the dash.
4. When air vents from the trailer-supply glad hand, the red valve should pop out automatically.
5. Press the brake pedal to confirm no air escapes the service glad hand.

“If the sequence behaves unexpectedly, the TPS requires a closer inspection,” he explained.

Screeton warned that contamination, such as dirt in the glad hand connection, can damage downstream components like the trailer relay valve, leading to dragging or brake release issues.

“When uncoupling glad hands, always use dummy couplers to keep out debris and prevent bigger problems,” he advised.

Stay Roadcheck-Ready with Expert Practices

Roadcheck initiatives like these are critical for reinforcing safety measures across North America. With proper maintenance and proactive checks, fleets and drivers can ensure compliance while enhancing overall safety.

By following these guidelines, you’ll meet safety standards and reduce your operational risks significantly. Stay safe out there!

During the event, which took place from August 25 to 31 across North America, certified inspectors from Canada, Mexico, and the United States examined 16,725 commercial vehicles. The results showed that a significant majority, 87%, were compliant with safety standards and could remain operational on public roads.

However, among the inspected vehicles, “2,149 of those vehicles had brake-related out-of-service violations, which is a 12.8% out-of-service rate,” according to the CVSA’s press release. Vehicles are classified as out of service when they fail to meet the critical inspection items outlined in the North American Standard Out-of-Service Criteria (OOSC). Such vehicles cannot resume travel until all identified issues are addressed.

Among the 2,149 vehicles with violations, 1,355, or 63.1%, were found to have stand-alone out-of-service brake violations. Meanwhile, 217 vehicles, accounting for 10.1%, had out-of-service violations related to the steering axle brakes. Furthermore, 1,216 vehicles, representing 56.6% of the total, did not meet the 20% defective brakes criteria, indicating that these vehicles had defective brakes comprising 20% or more of their braking system.

This year, Brake Safety Week highlighted lining and pad violations. Inspectors focused on identifying issues such as loose, missing, or worn brake linings/pads, as well as cracks or contamination. A total of 654 lining/pad violations were found across both power (tractor) and towed (trailer) units.

The event saw participation from 61 jurisdictions:

• In Canada, 1,926 inspections resulted in 243 brake-related out-of-service violations, translating to a 12.6% out-of-service rate, with 44 power units and 49 towed units showing lining/pad violations.

• Mexican inspectors conducted 107 inspections, finding six out-of-service violations—a 5.6% rate—with one power unit and five towed units having lining/pad issues.

• In the U.S., 14,692 inspections led to 1,900 out-of-service violations at a rate of 12.9%, with lining/pad violations noted on 310 power units and 172 towed units.

Additionally, 18 states used performance-based brake testers (PBBT) for 452 inspections, with a failure rate of 5.75%.

Brake Safety Week is an integral component of the CVSA’s Operation Airbrake Program, which is committed to enhancing brake safety in commercial vehicles throughout North America. The initiative aims to minimize accidents due to malfunctioning brakes by conducting roadside inspections and educating stakeholders on the significance of proper brake maintenance.

The next Brake Safety Week is set for August 24-30, 2025.
