Who Is Liable When Brake Failure Causes a Car Accident?

Few experiences behind the wheel feel as terrifying as pressing the brake pedal and getting no response. In the seconds that follow, drivers often have no way to avoid a collision, and the resulting crash can leave victims with serious injuries and a pile of questions. Who caused this? Was it something the other driver should have caught? Could a mechanic or manufacturer be responsible instead? That confusion often arrives alongside medical bills, lost wages, and a long road to physical healing.

At Saks, Robinson & Rittenberg, Ltd., we help injured people find answers during this difficult time. Our team investigates the cause of brake failure accidents and identifies every party who may share fault, so you can focus on recovering from your injury.

Liability in a brake failure crash typically depends on a few key factors:

• Whether the driver or vehicle owner neglected required brake maintenance
• Whether a mechanic or repair shop performed faulty service on the vehicle
• Whether a manufacturing or design flaw caused the brake component to fail
• Whether Illinois’s comparative fault rules affect how much compensation you can recover

How Do Investigators Determine Whether Brake Failure Caused the Crash?

After a crash, investigators look closely at physical evidence to confirm whether brake failure played a role. This often includes examining brake pads, rotors, calipers, and fluid lines for signs of wear, damage, or defect. Police reports, witness statements, and skid mark patterns (or the lack of skid marks) can also point to a braking problem.

Accident reconstruction experts frequently get involved in more serious cases. These experts recreate the crash using physical evidence and vehicle data to pinpoint exactly what went wrong and when.

When Can the Driver or Vehicle Owner Be Responsible for Poor Maintenance?

Illinois law requires every motor vehicle to have brakes that are adequate to control, stop, and hold the vehicle, and it specifically states that brakes must be maintained in good working order. This means drivers and vehicle owners have an ongoing duty to keep their braking system safe.

If a driver ignored warning signs, such as a squealing noise, a dashboard warning light, or a brake pedal that felt spongy or required extra pressure, and continued driving anyway, they may be held responsible for a resulting crash. The same responsibility can extend to vehicle owners who lend their car to someone else without disclosing a known brake problem.

When Can a Repair Shop, Parts Manufacturer, or Other Company Be Liable?

Not every brake failure traces back to the driver. Several other parties may share liability, including:

• Repair shops and mechanics: A shop that installs a defective part or performs a botched repair owes a duty of care to anyone who later drives that vehicle.
• Manufacturers: Illinois recognizes strict product liability, meaning a manufacturer can be held responsible for a defective brake part regardless of negligence, as long as the defect made the product unreasonably dangerous. This can include manufacturing defects, design defects, and failures to warn about a known danger.
• Commercial fleet owners: Companies that operate delivery vehicles, rideshare vehicles, or trucks may bear responsibility if they failed to maintain their fleet according to required standards.

Which Inspection Reports, Maintenance Records, and Vehicle Data May Help Prove the Cause?

Building a strong claim means gathering documentation that clearly shows what caused the brake failure. Our team often relies on:

• Vehicle maintenance and repair records
• Manufacturer recall notices tied to the vehicle’s make and model
• Mechanic inspection reports and expert testimony
• Photos and documentation from the crash scene

Illinois follows a modified comparative fault rule under 735 ILCS 5/2-1116, meaning you can still recover damages as long as you are found less than 51% at fault for the crash. If several parties contributed to the brake failure, fault and any compensation may be divided among them.
