The OTR1602B heavy‑duty brake drum is engineered for commercial trucks that demand consistent stopping power and long service life. Precision balancing minimizes vibration and promotes even lining contact, helping improve braking feel and reduce irregular wear. The robust cast construction handles thermal cycling and high loads common to vocational, regional haul, and OTR duty cycles, resisting heat checking and deformation under repeated stops. Sized at 16.50 x 7.0, this drum supports a wide swath of heavy‑truck applications and integrates smoothly into standard wheel‑end service routines. At approximately 112 lb, the drum’s mass contributes to stable thermal performance, helping dissipate heat and maintain predictable friction characteristics in steep grade, heavy payload, and stop‑and‑go environments. Consistent machining supports straightforward installation, proper runout control, and reliable fit with quality brake shoes and hardware. Whether refreshing a single axle or rebuilding an entire fleet, technicians benefit from a drum that helps maintain alignment, reduces noise and pulsation complaints, and supports DOT‑ready braking performance. Pair with premium linings, new hardware, and correct torque procedures to realize the full value of the design. For fleets focused on total cost of ownership, the OTR1602B offers durability, balance accuracy, and dependable braking that keeps vehicles in service and drivers confident behind the wheel.
