Chrysotile (white) asbestos in brake pads legally causes peritoneal mesothelioma, according to a July 2025 New York court of appeals opinion.

Case Background

Originally, an automobile dealership employee filed a personal injury action against Ford Motor Company, alleging that asbestos exposure from brakes while working at an automobile dealership caused his peritoneal mesothelioma. According to court documents, the automobile manufacturer manufactured, distributed, or supplied the asbestos-containing products (specifically friction products) and failed to exercise reasonable care in providing an adequate warning of the hazards of exposure to asbestos fibers.

The employee spent four years primarily delivering parts and one year at the counter in the parts department at the dealership. 

After a trial, which included expert testimony regarding general and specific causation, jurors found in favor of the employee. The automobile manufacturer appealed, arguing that the evidence presented at trial was legally insufficient.

A divided appeals court ruled that the evidence established “a valid line of reasoning and permissible inferences that could lead rational persons to the conclusion reached by the jury based upon the evidence presented at trial,” and therefore “the jury’s verdict satisfies “the minimal ‘not utterly irrational’ appellate review test.”

Court Verdicts and Settlements

Successful appeals are very rare in civil cases. However, in most asbestos exposure matters, defendants file appeals to delay the process, not to change the result.

Standard of Review in Appellate Case

The standard of review varies in different states. New York’s “not utterly irrational” test is a typical one. Think of an umpire calling balls and strikes. Appellate courts usually don’t second-guess umpires (judges and juries) in borderline cases. However, if the umpire called one of these pitches a strike, an appellate court may intervene.

So, favorable trial verdicts usually hold up in appeals court. Nevertheless, in most cases, a bird in the hand is worth two in the bush. In this context, a compromise settlement agreement is usually preferable to a court verdict.

Appellate Review as a Litigation Tactic

Finality may be the main reason a settlement is better than a verdict, at least in most cases. Defendants cannot appeal settlements. But they can appeal court verdicts and tie them up in court for years or even decades.

Additionally, settlements give victims more control over the outcome. Juries are notorious;y unpredictable. Too many variables are involved. We’ll tell two quick war stories that illustrate this point.

One of our colleagues once tried a case for an out-of-town victim. He carefully concealed the fact that he was from out of town, so as to not antagonize jurors. But one juror noticed that he wore the same pair of shoes every day. The panel ruled against the “big city lawyer.”

Another colleague cut off a juror in the parking lot one morning. The panel sided with the victim but reduced the amount of compensation, so that big-shot lawyer couldn’t afford another Porsche.

The bottom line is that a settlement isn’t always the best option for an asbestos exposure lawyer. But it’s almost always the best option.

Settlement is a process, not a result. Part of that process is carefully establishing every element of a negligence case. These elements include general and specific causation.

General causation is basically a foreseeable (possible) connection between the action (or inaction) and the damages. In the above case, according to the appellate court, a professor of epidemiology testified that chrysotile asbestos causes mesothelioma.

Expert Testimony Supported Finding Asbestos as the Culprit

More importantly, an environmental scientist assessed the brake’s asbestos composition. His tests showed that the manufacturer’s brakes contained between 25 percent and 50 percent chrysotile asbestos fibers. Additionally, handling brakes created asbestos dust, according to the expert. 

So, the evidence didn’t conclusively establish a link between asbestos and peritoneal mesothelioma. But the evidence established a possible connection.

Specific causation is basically cause-in-fact. In this case, the plaintiff was required to show that he was exposed to sufficient levels of the toxin to cause his alleged injuries.

According to evidence presented at trial, sanding released asbestos fibers at a rate of 0.8 to 2.2 fibers per cubic centimeter in the breathing zone of the worker. Furthermore, cleaning up dust with compressed air resulted in a recorded exposure level of 0.9 fibers per cubic centimeter, and sweeping after brake work was done produced a recorded exposure level of 1.7 fibers per cubic centimeter. 

In addition, the employee performed over a thousand brake jobs in a “dusty” garage. Furthermore, a physician testified, within a reasonable degree of medical certainty, that the type of cumulative exposure the employee received was a substantial factor in causing the employee’s mesothelioma.

Pleural mesothelioma is a rare and aggressive form of lung cancer. Peritoneal mesothelioma is a similar disease that develops in the abdomen.

Asbestos Illness Causation Issues

Two other causation issues appear frequently in asbestos exposure cases. These issues are the extended latency period in asbestos exposure illnesses and legacy asbestos in buildings constructed before 1980.

Mesothelioma’s latency period is usually about fifty years. In other words, if Mike handled asbestos-laced brake pads in 1975, a malignant tumor begins making him ill in 2025. A lot can happen in fifty years, making it difficult for an asbestos exposure lawyer to connect a specific incident to his illness.

The good news is the burden of proof in a civil claim is only a preponderance of the evidence (more likely than not). So, an asbestos exposure lawyer doesn’t have to “prove” the brake pads caused Mike’s mesothelioma. A lawyer must only establish a probable connection.

On a related note, despite the clear evidence that asbestos caused cancer, the government took little action, until a March 2024 chrysotile asbestos ban.

Legacy asbestos is usually an issue in demolition and renovation projects. Old buildings built before 1980 usually contain asbestos. But this mineral is odorless, colorless, and tasteless. Furthermore, asbestos fibers are microscopic and almost impossible to see.To avoid liability, property owners should always include asbestos remediation (testing, removal, and disposal) in their demolition and renovation plans.
