Carlisle Brake Lining

Product Description

Carlisle Companies produced asbestos-phenolic brake linings and friction products for automotive, truck, and industrial applications during the asbestos era. Carlisle’s brake products were distributed through automotive aftermarket channels and used at brake shops and fleet maintenance facilities nationwide.

The Carlisle Companies product line included brake shoes, brake blocks, and roll-stock friction material — all manufactured with the standard asbestos-phenolic formulation common to the brake industry through the asbestos era.

Asbestos Content

Litigation records document that Carlisle Brake Lining was alleged to have contained asbestos fiber as a functional filler or reinforcing agent. Asbestos fibers were incorporated into industrial materials of this category to enhance heat resistance, mechanical strength, dimensional stability under thermal cycling, and electrical-insulation properties.

Plaintiffs alleged that asbestos fibers in Carlisle Brake Lining were typically chrysotile, amosite, or a combination thereof — consistent with industry practice for the asbestos era. When the cured material was subjected to mechanical operations (drilling, grinding, sanding, machining, cutting) or when raw material was handled and processed, those fibers could become airborne.

How Workers Were Exposed

Litigation records document multiple exposure pathways for workers who handled Carlisle Brake Lining:

Raw material handling: Workers who received, weighed, blended, or transferred the material in production environments could disturb settled asbestos fibers and generate airborne dust.

Manufacturing operations: Workers operating the production equipment — molding presses, lamination presses, compounding mixers, cutting saws — were exposed during normal operation, equipment cleaning, and routine maintenance.

Machining and finishing of finished material: Secondary operations including drilling, reaming, turning, grinding, sanding, sawing, and routing of Carlisle Brake Lining generated fine dust containing asbestos fibers. These operations were performed by machinists, toolmakers, electricians, and assembly workers who may not have been informed that the material contained asbestos.

Maintenance and tooling work: Maintenance workers responsible for cleaning equipment, servicing presses and mixers, and disposing of accumulated dust in facilities that produced or processed Carlisle Brake Lining could encounter substantial exposure during cleaning and repair operations.

The occupational exposures associated with asbestos-containing industrial laminates and molding compounds are consistent with patterns recognized by OSHA and NIOSH. The latency period for asbestos-related diseases is typically 20-50 years between initial exposure and diagnosis, meaning workers exposed to products like Carlisle Brake Lining during the mid-twentieth century may be receiving diagnoses today.
