Military Truck Brake Systems — Asbestos Exposure Crosswalk

What This Equipment Is

The U.S. military operated (and operates) an enormous fleet of wheeled vehicles — cargo trucks, tactical trucks, prime movers, fuel and water tankers, refrigeration vans, recovery vehicles, special-purpose vehicles, generator sets, trailers, and base support vehicles. From WWII through the late 1980s, the brake-friction material across the fleet was overwhelmingly asbestos-bonded composite, paralleling Brake Linings for civilian vehicles.

Major vehicle categories included:

  • WWII-era trucks — GMC CCKW, Studebaker US6, Diamond T, Mack NO, Dodge WC, jeeps
  • Postwar standard trucks — M35 (2½-ton), M54 (5-ton), M809-series, M939-series, M1078-series (LMTV / FMTV)
  • Heavy haulers / prime movers — M520 Goer, HEMTT (M977), M911 / M915 / M916 / M917 tractor-trailer combinations, LVS
  • HMMWV (“Humvee”) — through earlier production
  • Trailers — extensive trailer fleet using brake systems
  • Base support vehicles — buses, fuel trucks, fire trucks, ambulances, refrigeration vans

Parallel exposure pathways apply to specialized military categories like Marine Corps Logistics Vehicle System (LVS), Navy Construction Battalion (Seabees) heavy equipment, and Air Force fuel-handling vehicles.

Why Military-Truck-Brake Work Was a Heavy Asbestos Exposure

Military mechanical maintenance — Army Wheeled Vehicle Mechanic (MOS 91B / 63B / 63W in successive systems), Marine Motor Transport Mechanic (USMC MOS 3521), and equivalent Air Force / Navy ground-vehicle MOSs — performed brake service across the fleet routinely. Each brake service involved removing wheels, blowing out accumulated brake dust with compressed air (the highest-exposure step), removing worn shoes / pads, and installing fresh asbestos friction material.

Depot maintenance at large military rebuild facilities concentrated brake-rebuild activity at industrial scale.

Reserve and National Guard unit motor pools — handling many vehicles that remained in service well past the 1980s — extended the asbestos exposure window for that workforce into the 1990s and beyond.
