Elevator & Escalator Brake Shoes — Asbestos Exposure Crosswalk
What This Equipment Is
Traction elevators are stopped and held by a friction brake that clamps onto the drive sheave or motor shaft when the elevator reaches its target floor or in an emergency stop. From the 1930s through the late 1980s, the dominant brake-shoe material in elevator service was an asbestos-bonded composite friction material — selected for its consistent friction coefficient, heat resistance, and low fade under repeated stops.
The same friction-material family appeared in:
- Traction elevator main brakes — on the drive motor or sheave
- Hydraulic elevator emergency brake assemblies
- Escalator drive brakes
- Dumbwaiter and freight-elevator brake systems
- Theater stage-lift and orchestra-pit-lift brakes
Why Elevator Brake Work Was an Asbestos Exposure Pathway
Elevator brake shoes wear at a controlled rate over many years of normal service. Brake replacement involves removing the drive cover, dismounting the brake assembly, removing the worn shoes (handling them in close proximity to the worker’s breathing zone), and installing fresh shoes. The classic compressed-air-blowout-and-brush-clean sequence on automotive brakes (see Brake Linings) translates directly to elevator brake service.
Elevator modernization projects — common in commercial high-rises, hospitals, and institutional buildings of 1930s–1980s vintage — typically replace entire brake assemblies and disturb decades of accumulated brake dust in the machine room.
