710W50110-0144 is the benchmark for heavy‑duty braking performance. Engineered for extreme loads, this high‑carbon brake drum delivers superior heat dissipation and wear resistance. As a core component of Howo/Sitrak truck parts, it ensures safety and durability in the most demanding logistics and mining operations. Every drum is precision‑balanced to reduce vibration, extending the service life of linings and hubs. With 710W50110-0144, fleet operators gain consistent stopping power and lower maintenance costs — a true upgrade for your heavy truck.
Built for Howo, Sitrak, and other heavy trucks, this brake drum meets OE specifications with high‑carbon alloy metallurgy. Its ribbed design improves cooling, while the precision‑machined friction surface ensures uniform contact. Every unit is 100% inspected for runout and hardness.
High‑carbon content (≥3.5%) and optimized wall thickness reduce thermal cracking, even under continuous braking on mountain roads.
Wear resistance increased by 28% vs. standard drums. Less downtime, more miles — proven in fleet tests.

The carbon content boosts tensile strength and thermal stability, preventing distortion and premature wear.
Each drum is dynamically balanced to reduce vibration, ensuring smooth braking and longer bearing life.
External cooling ribs increase surface area, dropping brake fade by up to 18% in downhill scenarios.
Precision‑machined mounting face and bolt holes guarantee direct replacement without modification.
This brake drum (high carbon) is tested under extreme conditions: from –40°C cold starts to 600°C continuous braking. The advanced metallurgy resists blue‑spot cracking, a common failure in lower‑grade drums. Fleet managers report 30% longer drum life compared to conventional cast iron. The 710W50110-0144 also reduces noise and judder, improving driver comfort.
Installing the 710W50110-0144 is straightforward. Clean the hub face, apply anti‑seize compound on the bolt threads, and torque to OEM specifications (450‑500 N·m). Regularly inspect the drum for scoring or heat checks. With proper maintenance, this high‑carbon drum can exceed 500,000 km of on‑highway service. For off‑road applications, the robust construction resists impacts from gravel and debris.
The metallurgical composition of this brake drum includes chromium and molybdenum additions, enhancing hardness without sacrificing ductility. This balance is critical for heavy vehicles that frequently encounter emergency braking. The drum’s friction surface is machined to a fine finish (Ra ≤ 2.5 µm), which minimizes lining wear and promotes even pad contact. Additionally, the ventilation slots (six per drum) expel hot gases, keeping the braking interface cool.
This drum is manufactured in ISO 9001:2015 and IATF 16949 certified facilities. 710W50110-0144 meets ECE R90 and DOT FMVSS 121 standards for brake components. 710W50110-0144 Random samples are subjected to dynamometer tests that simulate 1,000 full‑load stops from 80 km/h. The high‑carbon material maintains friction stability within ±5% across the entire temperature range.
Compared to standard grey iron drums, the 710W50110-0144 offers a 22% reduction in thermal expansion, which translates to more consistent pedal feel and reduced brake fade. For fleets operating in mountainous terrain, this drum is the preferred upgrade. Its compatibility with both drum‑ and disc‑brake equipped trailers makes it a versatile choice for mixed fleets.
Regular ultrasonic thickness checks are recommended after 200,000 km. The high‑carbon construction provides visual wear indicators (two grooves on the friction surface) that allow quick inspection without disassembly. This feature simplifies preventive maintenance scheduling and reduces unplanned downtime.
Lower rolling resistance due to reduced weight and better concentricity can improve fuel economy by up to 1.2%.
The high‑carbon material dampens vibrations, resulting in quieter braking – especially under partial load.
In summary, the 710W50110-0144 high‑carbon brake drum combines durability, thermal stability, and precision fitment. It is a direct replacement for Howo and Sitrak trucks, offering OEM‑grade quality at a competitive cost. Whether you operate in mining, construction, or long‑haul logistics, this brake drum delivers reliability that keeps your fleet moving.
