AMMCO Tools and Asbestos-Containing Brake Products
Company History
AMMCO Tools is an American manufacturer best known for producing automotive brake service equipment, including brake lathes, drum turning machines, and related shop tools. The company established itself as a significant supplier to the automotive repair industry, and its equipment became a fixture in dealerships, independent repair shops, fleet maintenance facilities, and vocational training programs throughout the United States.
AMMCO’s brake service machinery was widely used across the country during the peak decades of asbestos use in the automotive trades — roughly the 1940s through the early 1980s. According to asbestos litigation records, the company’s connection to asbestos exposure stems not from asbestos embedded in its heavy machinery itself, but from the company’s role as a manufacturer and seller of brake-related consumable products, including brake pads and brake shoes, that plaintiffs allege contained asbestos fibers during this period.
The automotive brake service industry relied heavily on asbestos-containing friction materials throughout the mid-twentieth century. Asbestos was valued in these applications for its heat resistance and durability under the intense friction conditions generated during braking. As a result, brake pads, brake shoes, and related friction components produced by numerous manufacturers — including, according to litigation records, AMMCO Tools — incorporated chrysotile asbestos and other asbestos fiber types as primary binding and friction-generating materials.
AMMCO Tools reportedly ceased incorporating asbestos into its friction products around the early 1980s, a period that coincided with growing regulatory pressure from agencies including the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), as well as increasing public awareness of the health hazards associated with asbestos exposure.
Asbestos-Containing Products
Court filings document that AMMCO Tools manufactured or distributed brake friction products alleged to have contained asbestos. Because the company’s primary business involved brake service equipment, its consumable product lines — the pads, shoes, and related friction components sold alongside its machinery — are the products most frequently identified in asbestos exposure litigation.
Plaintiffs alleged that AMMCO-branded or AMMCO-distributed brake pads and brake shoes contained asbestos as a primary component of the friction material. These products were designed for use with AMMCO brake lathes and drum turning equipment but were also sold for broader automotive service use.
According to asbestos litigation records, the relevant product categories associated with AMMCO Tools include:
- Brake pads — Disc brake friction pads alleged to contain chrysotile asbestos within the friction compound bonded to metal backing plates.
- Brake shoes — Drum brake shoes with friction linings alleged to contain asbestos, used in passenger vehicles and light trucks.
- Brake service consumables — Additional friction-related materials sold or distributed by AMMCO in connection with its brake service machinery lines.
The specific asbestos fiber content of these products, the precise formulations used, and the dates of manufacture are matters that have been addressed through discovery in civil litigation. Plaintiffs alleged that these products, when used as intended — grinding, turning, cutting, and cleaning brake surfaces — released respirable asbestos dust into the breathing zone of automotive workers.
It should be noted that the documentation of specific product model names and catalog numbers associated with AMMCO Tools’ asbestos-containing product lines is an area where litigation records and company documents obtained through discovery provide the most authoritative reference. Workers and attorneys researching specific exposure histories are encouraged to consult litigation counsel with access to product identification records developed in prior cases.
Occupational Exposure
The workers most commonly identified in asbestos litigation involving AMMCO Tools products are those employed in automotive service and brake repair occupations. Court filings document allegations from workers across a range of job classifications, including:
- Brake mechanics and automotive technicians who routinely serviced drum and disc brake systems, grinding, turning, and replacing friction components
- Dealership service department workers who performed brake jobs on new and used vehicles using AMMCO equipment and related friction products
- Fleet maintenance personnel at trucking companies, municipal agencies, and large commercial operations where brake service was performed regularly
- Vocational and trade school instructors and students trained on AMMCO brake service equipment in programs that used the company’s machinery and friction product lines
- Auto parts store employees who handled, cut, or distributed brake friction products
According to asbestos litigation records, the exposure mechanism most frequently alleged in cases involving brake friction products is the generation of asbestos-containing dust during routine brake service tasks. These tasks included:
- Brake drum and rotor resurfacing using AMMCO lathes, which generated fine particulate matter from worn friction surfaces
- Removal and installation of brake shoes and pads, during which old, worn asbestos-containing linings were disturbed, creating airborne dust
- Cleaning of brake assemblies using compressed air, brushes, or solvents — methods that were standard practice before the adoption of enclosed vacuum systems and wet cleaning protocols
- Grinding and beveling of new brake linings to fit specific drum dimensions, a task that produced high concentrations of airborne dust
Plaintiffs alleged that these routine tasks, performed in enclosed shop environments with limited ventilation, resulted in repeated and sustained inhalation of asbestos fibers over the course of their working careers. Asbestos-related diseases that have been the subject of litigation in connection with brake product exposures include mesothelioma, asbestosis, lung cancer, and other asbestos-related conditions.
OSHA has maintained regulatory standards governing occupational asbestos exposure since the 1970s, and EPA regulations under AHERA and related programs address asbestos in various settings. The automotive brake service industry was identified as a significant source of occupational asbestos exposure in regulatory guidance documents, supporting the biological plausibility of the exposure mechanisms described in litigation filings.
Secondary or household exposure has also been alleged in some litigation contexts, with family members of brake mechanics claiming exposure through asbestos fibers brought home on work clothing, skin, and hair — a pathway sometimes referred to as take-home or para-occupational exposure.
Trust Fund / Legal Status
AMMCO Tools is a Tier 2 manufacturer for purposes of asbestos litigation research. The company has been named as a defendant in asbestos personal injury litigation, but as of the time of this writing, AMMCO Tools has not established a bankruptcy reorganization trust under Section 524(g) of the U.S. Bankruptcy Code. This means there is no dedicated AMMCO asbestos trust fund through which claimants can file for compensation directly.
According to asbestos litigation records, claims against AMMCO Tools have been pursued through conventional civil litigation in state courts. Plaintiffs have alleged that the company’s brake friction products caused asbestos-related disease, and cases have proceeded through the traditional discovery, trial, and settlement processes characteristic of asbestos personal injury litigation. Court filings document that AMMCO Tools has appeared as a named defendant in multi-defendant asbestos cases alongside other brake product and friction material manufacturers.
Because no dedicated trust fund exists, individuals seeking compensation for asbestos-related disease allegedly caused by exposure to AMMCO Tools products must pursue their claims through civil litigation rather than through a streamlined trust fund claim process.
What This Means for Workers and Families
If you or a family member worked as a brake mechanic, automotive technician, fleet maintenance worker, or in another trade that involved regular use of brake service equipment and friction products — and you have been diagnosed with mesothelioma, lung cancer, asbestosis, or another asbestos-related disease — your exposure history may include products alleged in litigation to have been manufactured or distributed by AMMCO Tools.
Because AMMCO Tools has not established an asbestos bankruptcy trust, any claim involving the company would be pursued through civil litigation. An experienced asbestos attorney can evaluate your exposure history, identify all potential defendants and available trust funds from other manufacturers involved in your work history, and advise you on the appropriate legal venue and strategy for your specific circumstances.
Automotive brake repair workers are frequently eligible to file claims against multiple trust funds established by other asbestos brake product and friction material manufacturers, in addition to any civil litigation claims. A comprehensive exposure history review is essential to identify the full range of products and manufacturers involved in a given worker’s career.
