Description
U.S. Military M39-Series 5-Ton 6×6 Brake-Shoe Parts Kit, NSN 2530-00-741-7135, P/N 7417135 / IHC 108345R91, January 1953
This U.S. military Parts Kit, Brake Shoe, identified by NSN 2530-00-741-7135, was supplied for the G744 M39-series 5-ton 6×6 truck family.
The kit carries Army stock/drawing number 7417135 and International Harvester part number 108345R91. This example was packed by Mack Manufacturing Corporation in January 1953, placing it among the early support parts produced for the M39 family.
One package contains two brake-shoe components used when servicing the truck's drum-brake system.
Historical Significance
The M39 series was developed after the U.S. Army decided to replace several World War II-era 4- to 6-ton tactical trucks with a standardized 5-ton, three-axle, all-wheel-drive family.
The new G744 trucks entered production in the early 1950s. Different bodies and chassis allowed the same basic vehicle family to perform cargo, dump, tractor, recovery, and other heavy transportation duties.
The G744 family included well-known vehicles such as the M51 dump truck, M52 tractor, M54 cargo truck, and M62 wrecker, along with numerous related variants.
These trucks remained important U.S. military vehicles for many years and later saw extensive use during the Vietnam War. This kit's January 1953 packaging date places it near the beginning of the M39-series service period.
What This Item Is and Does
This kit contains replacement components for the brake-shoe assemblies used in the M39-series truck's drum brakes.
Brake shoes carry the friction material that presses against the inside surface of the brake drum when the braking system is applied. Parts kits like this allowed military maintenance personnel to replace worn or damaged brake components without replacing an entire unrelated brake assembly.
This is a brake-shoe service-parts kit. It is not a complete brake drum, wheel cylinder, backing plate, air-hydraulic unit, or complete wheel-brake assembly.

Why This Item Matters
Original maintenance parts from the first years of M39-series production are useful for restorations because they preserve the military part numbers, manufacturer cross-references, and packaging information used by Army supply personnel.
This kit is especially interesting because its markings connect International Harvester, which developed the original M39-series design, with Mack, one of the manufacturers involved in G744 production and military support.
Its 1953 package date also makes it a collectible example of early Cold War military vehicle maintenance equipment.
