Brake drum systems for Kamaz trucks require precision engineering to withstand extreme loads. Designed for commercial vehicles carrying 12+ tons, Kamaz brake drums exhibit 23% higher thermal stability than standard models, reducing warping risks during prolonged downhill braking. These components directly impact operational safety, with 89% of fleet managers prioritizing OEM-compliant drum brake drum replacements to maintain factory performance.
Kamaz-approved brake drums utilize high-carbon cast iron (3.2% carbon content) with chromium reinforcement (1.5% alloy composition), achieving:
Dual-phase heat treatment ensures Brinell hardness of 220-240 HB, outperforming generic alternatives by 34% in abrasion resistance.

A: The brake drum in KAMAZ trucks provides a friction surface for brake shoes, converting kinetic energy into heat to slow or stop the vehicle. It is critical for reliable heavy-duty braking performance.
A: Replacement intervals depend on usage, but regular inspections for cracks, wear limits (typically 1-2mm over specification), or scoring should be conducted every 30,000-50,000 km.
A: The terms are often interchangeable, but "drum brake drum" specifically refers to the rotating component in drum brake systems, while "brake drum" is a general term applicable to various vehicle types.
A: Regular cleaning to remove brake dust, checking shoe lining thickness (minimum 3mm), and ensuring proper adjustment to prevent dragging significantly extends component life.
A: When brakes are applied, hydraulic pressure pushes the brake shoes against the rotating brake drum's inner surface, creating friction that decelerates the wheel assembly.
