Truck Brake Failure Accidents
Truck brake failures are usually caused by poor maintenance, such as brakes out of adjustment or worn components, rather than sudden defects. Federal rules require carriers to inspect, repair and maintain their trucks and keep records. When brakes fail, the carrier, a maintenance contractor or a parts manufacturer can be liable.
Why do truck brakes fail?
Air brakes on heavy trucks need regular adjustment and inspection. Common failures include:
- Brakes out of adjustment, which reduces stopping power.
- Worn pads, drums or linings.
- Air system leaks or damaged hoses.
- Overheated brakes on long downhill grades.
- Defective parts or faulty repairs.
What maintenance rules apply?
Carriers must systematically inspect, repair and maintain their vehicles and keep maintenance records (49 CFR 396.3). Drivers must complete inspection reports noting defects (49 CFR 396.11), and each vehicle needs a periodic inspection at least every 12 months (49 CFR 396.17). Brake requirements are in 49 CFR 393.40-393.55. Brake violations are among the most common reasons trucks are taken out of service at roadside inspections.
How do you prove brake failure caused the crash?
The truck itself is the main evidence, so it should be preserved and inspected by an independent expert before repair. Maintenance records, driver inspection reports and the carrier's roadside inspection history (available through FMCSA) can show whether problems were known and ignored.
Frequently asked questions
Who is liable when a truck's brakes fail?
Usually the trucking company, which must keep its vehicles properly maintained. A third-party maintenance shop or a parts manufacturer can also be liable if faulty repairs or defective parts caused the failure.
How often must truck brakes be inspected?
Drivers must report defects they find, carriers must inspect and maintain vehicles systematically, and every truck needs a periodic inspection at least once every 12 months under federal rules.
Can I find out if the truck had brake problems before?
Often, yes. FMCSA publishes carriers' roadside inspection and violation histories, and maintenance records can be obtained in a claim.
What if the truck was repaired before anyone inspected it?
Destroying or altering evidence after a claim is anticipated can lead to court sanctions. That is why a preservation letter should be sent quickly.
Is brake failure ever the driver's fault?
It can be. Drivers must inspect their vehicles and manage speed on grades, and overheating brakes on a long descent can reflect poor driving technique.
