Arvin Meritor (Rockwell Brakes) – Asbestos Brake Products Reference

Company History

Rockwell International and its predecessor entities were major American manufacturers of heavy-duty brake systems and friction components throughout the mid-twentieth century, supplying brakes to the commercial trucking, automotive, and industrial equipment sectors. The brake and friction division operated under the Rockwell name for decades before a series of corporate reorganizations and mergers eventually produced Arvin Meritor, Inc., a global supplier of drivetrain, mobility, braking, and aftermarket solutions for commercial vehicle and industrial markets.

Meritor Automotive, Inc. was formed in 1997 when Rockwell International spun off its automotive operations. That entity subsequently merged with Arvin Industries in 2000 to form ArvinMeritor, Inc. (later styled Arvin Meritor). The combined company inherited the manufacturing legacy, product lines, and legal liabilities associated with decades of brake component production under the Rockwell name. Throughout much of the postwar period — roughly the 1940s through the early 1980s — asbestos was a standard component of friction materials used in drum brakes, brake linings, and related assemblies manufactured under the Rockwell brand.

Asbestos was prized by friction material manufacturers for its heat resistance, durability, and low cost. Heavy-duty drum brake systems in particular generated substantial frictional heat during operation, making asbestos-reinforced linings the industry-standard choice for commercial trucks, buses, trailers, and off-road equipment. Rockwell brakes were widely specified by original equipment manufacturers and were also sold as replacement components through commercial aftermarket channels.

Asbestos-Containing Products

According to asbestos litigation records, Rockwell-branded brake systems and friction components manufactured through approximately the early 1980s contained asbestos in their friction material formulations. Court filings document that the following categories of products have been identified in exposure claims:

Heavy-Duty Drum Brake Assemblies Rockwell manufactured drum brake systems used extensively on Class 6, 7, and 8 commercial trucks and trailers. Plaintiffs alleged that the brake shoes and bonded or riveted brake linings incorporated into these assemblies contained chrysotile asbestos, and in some formulations, additional amphibole fiber types, as friction-enhancing and heat-dissipating agents.

Brake Linings and Friction Pads According to asbestos litigation records, Rockwell supplied brake lining materials — both as original equipment on brake assemblies and as aftermarket replacement linings — that plaintiffs alleged contained asbestos fiber content consistent with friction material industry standards of the era. These linings were designed to be periodically replaced as part of routine brake maintenance.

Air Brake Components Rockwell was a leading supplier of air brake systems to the commercial trucking industry. Court filings document claims that air brake friction components — including the lining material on S-cam drum brake shoes, a design Rockwell helped popularize — incorporated asbestos in their friction surfaces through at least the late 1970s or early 1980s.

Aftermarket Replacement Parts Plaintiffs alleged that Rockwell-branded replacement brake linings and shoe kits were sold through commercial parts distributors and fleet maintenance channels well into the period when asbestos-containing friction materials remained in commerce. Workers performing brake relines on commercial vehicles would have encountered these components during routine service operations.

It should be noted that the precise asbestos fiber content, specific product model designations, and the exact timeline of reformulation to non-asbestos materials have been subjects of dispute in litigation. According to asbestos litigation records, the transition away from asbestos-containing friction materials occurred across the industry in the late 1970s and early 1980s, though the specific cutoff date for Rockwell products has varied in court filings and plaintiff claims.

Occupational Exposure

According to asbestos litigation records, the occupational groups most frequently identified as having potential exposure to Rockwell/Arvin Meritor brake products include mechanics, brake specialists, and maintenance personnel who worked on commercial vehicles and heavy equipment.

Brake Mechanics and Fleet Maintenance Workers Court filings document that the brake relining process — which involved removing worn brake shoes, grinding or cleaning brake drums, and bonding or riveting new lining material — was a primary source of asbestos fiber release. Plaintiffs alleged that this process generated respirable asbestos dust that workers inhaled during routine maintenance activities performed in commercial garages, fleet maintenance shops, and trucking company facilities.

Grinding and Machining Operations According to asbestos litigation records, brake drum resurfacing and brake shoe grinding operations were identified as particularly high-dust tasks. Workers using bench grinders, lathes, or hand tools to shape or resurface asbestos-containing brake components allegedly created concentrated asbestos fiber clouds in enclosed or poorly ventilated shop environments.

Military and Government Fleet Mechanics Rockwell brake systems were specified for use on military vehicles and government fleet equipment. Court filings document claims from mechanics who serviced military trucks, trailers, and heavy equipment fitted with Rockwell brake assemblies, alleging exposure during brake inspection and replacement procedures conducted on military installations and government maintenance facilities.

Assembly Line and Manufacturing Workers Plaintiffs alleged that workers involved in the manufacturing or assembly of Rockwell brake components — including those who cut, bonded, or handled raw friction lining material — faced potential asbestos exposure in production environments prior to engineering controls or regulatory requirements.

Secondary and Bystander Exposure According to asbestos litigation records, claims have also been brought by workers who were present in the same shop environments as brake mechanics — including parts runners, shop supervisors, and general laborers — who alleged bystander inhalation exposure to asbestos dust generated during brake work.

The brake-friction trade presents a well-documented occupational asbestos exposure pathway recognized in epidemiological and industrial hygiene literature. Regulatory guidance developed under OSHA and EPA frameworks has acknowledged that asbestos-containing brake components, when abraded, ground, or disturbed, can release respirable chrysotile and other asbestos fiber types at concentrations potentially hazardous to workers.

Trust Fund / Legal Status

No Asbestos Bankruptcy Trust Has Been Established

Arvin Meritor, operating as the corporate successor to the Rockwell brake and friction business, has not filed for asbestos-related bankruptcy protection, and no dedicated asbestos bankruptcy trust fund exists through which claimants can file administrative claims. This distinguishes Arvin Meritor from a number of other friction product manufacturers who resolved their asbestos liabilities through Chapter 11 reorganization and the establishment of Section 524(g) trusts.

According to asbestos litigation records, Arvin Meritor and its predecessor entities have been named as defendants in asbestos personal injury litigation in courts across the United States. These cases have proceeded through the traditional civil litigation system rather than through a trust fund claims process. The company has disputed liability in many of these cases, and the outcomes of individual cases have varied.

It is worth noting that Meritor, Inc. (formerly ArvinMeritor) has continued to operate as a going concern. As of the time of publication, claimants alleging asbestos-related disease from exposure to Rockwell-branded brake products must pursue their claims through traditional civil litigation channels rather than through a trust fund filing process.

If you or a family member worked as a brake mechanic, fleet maintenance technician, or in any capacity that involved regular contact with Rockwell or Arvin Meritor brake components — particularly heavy-duty commercial truck brake systems manufactured before the early 1980s — and have been diagnosed with mesothelioma, asbestos-related lung cancer, asbestosis, or another asbestos-related disease, the following information is relevant to understanding your legal options:

  • No trust fund is currently available for Arvin Meritor / Rockwell brake claims. Claims cannot be submitted administratively through a trust fund process.
  • Civil litigation is the available legal route. Claims against Arvin Meritor and its predecessors have been litigated in asbestos dockets across the country. An experienced asbestos attorney can evaluate whether a civil claim is appropriate based on your documented exposure history.
  • Other trust funds may apply. Workers exposed to Rockwell brakes often had concurrent exposure to other asbestos-containing products — including gaskets, insulation, and friction materials from other manufacturers — many of whom have established bankruptcy trusts. A thorough exposure history review may identify additional trust fund claims.
  • Documentation matters. Employment records, union records, parts invoices, vehicle maintenance logs, and co-worker testimony have all been used in litigation to establish exposure to specific Rockwell brake products at identified worksites and time periods.

According to asbestos litigation records, Arvin Meritor has been a named defendant in numerous asbestos personal injury cases. Anyone researching a potential claim should consult with legal counsel experienced in asbestos litigation to evaluate the specific facts of their exposure history and diagnosis.
