Brake Safety Week Results Put 15 Percent of Inspected Trucks Out of Service

What the Brake Safety Week numbers show

On November 9, 2026, Trucking Info (Heavy Duty Trucking) published the results of the Commercial Vehicle Safety Alliance's 2026 Brake Safety Week, the seven day enforcement push that ran August 23 through 29. Inspectors in the United States looked at 14,165 commercial vehicles and placed 2,134 of them out of service for brake violations. That works out to 15.1 percent, which the outlet described as little changed from the 2025 campaign, when close to 15 percent of U.S. vehicles were sidelined.

Those were not quick walkarounds either. According to the report, 91 percent of the inspections across North America were full Level I inspections, the 37 step version where the inspector gets under the truck. Brakes also led the vehicle out of service list at this year's International Roadcheck, so this is not a one week blip. It is the most common reason a truck gets parked at roadside, year after year.

Where the trucks actually failed

The biggest single problem was the 20 percent defective brake rule. Across North America, 1,176 vehicles, almost half of all the brake out of service trucks, had enough brakes out of adjustment or otherwise defective to trip that threshold. Hoses and tubing came next at 600 violations, followed by 145 for excessive air loss. Steering axle brakes drew 119 non lining violations and 92 lining violations, and 759 more landed in a catch all bucket that covers air tanks, tractor protection systems, parking brakes and low air warning devices.

This year's named focus was brake drums and rotors. Inspectors wrote 141 drum and rotor violations and put 64 vehicles out of service for them. Rusted rotors led that list, followed by broken drums, broken rotors and metal to metal contact. Trucking Info noted that most rotor problems were on air disc brakes, while every broken drum was on an S cam setup. In the 12 U.S. jurisdictions that used performance based brake testers, 657 vehicles were tested and 29 fell short of the 43.5 percent minimum braking efficiency.

Why a brake violation is an insurance problem

An out of service order costs you the day, the appointment and maybe the load. That part is obvious. The part owner-operators tend to underestimate is how long the inspection report lives after the truck is fixed. Brake violations land in your vehicle maintenance history, and that history is one of the first things an underwriter looks at when you shop a renewal or start new authority. A clean inspection record helps your price. A pattern of brake and out of service violations works against it, and it can narrow the list of markets willing to write you at all. If you want to understand what drives the number, our guide on how much commercial truck insurance costs walks through the factors.

The bigger risk is what happens after a crash. If a truck with known brake problems rear ends someone, the plaintiff's attorney will ask for every inspection report and every maintenance record on that unit. A prior brake violation that was never written up as repaired turns a routine claim into a negligence story. That is exactly the kind of case that tests your commercial auto liability limits, and it is why the paperwork matters as much as the repair.

Your own truck pays too

Brakes that fade or pull do not only hurt the other driver. A truck that cannot stop in time is a truck that gets damaged, and repairing a modern tractor is not cheap. Physical damage coverage is what pays to fix or replace your own equipment after a covered loss, and lenders usually require it on a financed truck. Keeping brakes in adjustment is one of the simplest ways to keep that coverage from ever being needed. If the load is damaged or delayed in the same event, that is a separate question for your motor truck cargo policy.

What to do before the next campaign

CVSA has already set the 2027 Brake Safety Week for April 18 through 24, so the next one comes in the spring rather than late summer. You do not need to wait for it. Check pushrod stroke and adjustment on every axle, look hard at hoses and lines for chafing, listen for air leaks at the start of the day, and pay attention to drums and rotors for cracks or heavy rust. Write down every repair with the date and the unit number, and keep the receipts where you can find them. If an inspector does find something, get the fix documented and file a correction if the record is wrong. Those records are your best defense at roadside, at renewal and in a courtroom.

A clean, well documented truck is easier to insure.
