Maximum braking reliability for heavy commercial vehicles – The OEM AZ9231340068 Brake Friction Pad (410 X 160) delivers superior stopping force, fade resistance, and extended service life under extreme loads. Designed as an integral component for SINOTRUK, HOWO, and SHACMAN axles, this friction pad guarantees consistent performance on mountain descents and high-speed highways. For guaranteed compatibility and original-equipment safety, always choose genuine Sinotruk Homan parts. The advanced non-asbestos organic (NAO) compound paired with a precision steel backing plate ensures low rotor wear and stable friction output across a wide temperature range. Fleet operators worldwide trust the AZ9231340068 to reduce total cost of ownership while meeting ECE R90 brake safety standards.
The AZ9231340068 Brake Friction Pad (410 X 160) is engineered using a high-performance ceramic‑metallic friction formulation. Unlike conventional linings, this pad maintains a stable coefficient of friction (0.42 μ) even after repeated hard braking. The integrally molded steel backing plate eliminates shear failure, while the multi‑layer shim technology reduces brake noise and vibration. Heavy-duty truck fleets operating in mountainous regions benefit from reduced brake fade and extended lining life, often achieving 20% more miles between replacements compared to standard aftermarket pads.
The NAO‑ceramic blend withstands continuous temperatures up to 600°C without glazing, ensuring consistent stopping power during long downhill grades.
Optimized abrasive level minimizes drum/disc wear. The AZ9231340068 extends brake drum life by up to 30%, lowering overall fleet maintenance costs.
Patented heat-sink layer dissipates thermal energy quickly, preventing brake fluid vaporization and maintaining pedal feel under continuous load.

The AZ9231340068 Brake Friction Pad integrates a three-layer friction interface: an underlayer for heat insulation, a working layer with stabilized friction modifiers, and a top coat that prevents rust during storage. The precision‑stamped backing plate features raised clinch studs that penetrate the friction material, eliminating delamination risks common with glued linings. Every production batch undergoes random dynamometer testing to simulate mountain braking (5‑km, 7% grade), ensuring that the AZ9231340068 maintains friction coefficient between 0.38 and 0.45 even after 50 repeated stops from 60 km/h.
Unlike cheap recycled linings, the AZ9231340068 uses virgin aramid fibers, thermally stable resins, and fine ceramic fillers. This recipe provides high mechanical strength and excellent fade recovery. The material is also low‑dust and compliant with EU Reach regulations, reducing environmental impact when pads are worn. Fleets operating in arctic conditions benefit from the pad’s consistent initial bite even at -30°C, while desert operators see no glazing after prolonged high-speed driving.
The AZ9231340068 is a direct OEM replacement for SINOTRUK HOWO A7, T7H, and SHACMAN F3000/F2000 front and rear drum brake systems. It also fits many third‑party axles using 410×160 brake shoes. Installation requires no modification; the pad slots into the existing brake shoe assembly. The integrated wear alert (mechanical spring clip) provides an audible warning when remaining friction material drops below 4 mm, allowing timely replacement without damaging the brake drum.
To ensure optimum performance and safety when fitting the AZ9231340068 Brake Friction Pad, follow these steps: 1) Remove the old lining and clean the brake shoe retaining grooves with a wire brush. 2) Inspect the brake drum for scoring or ovality; replace if wear exceeds 2 mm. 3) Apply a thin layer of high‑temperature anti‑seize paste on the pad’s backplate contact points. 4) Insert the new AZ9231340068 pad into the shoe holder until the retaining pin clicks. 5) Repeat for all wheel positions, ensuring the wear indicator faces the rotational direction. 6) Perform a burnish procedure: 20 gentle stops from 40 km/h to 10 km/h to condition the friction surface.
The AZ9231340068 requires periodic visual checks every 25,000 km. Measure remaining friction thickness through the inspection hole; replace when the thickness is below 5 mm to preserve drum integrity. Never wash brake assemblies with gasoline or aggressive solvents – use only compressed air or a brake cleaner that does not dissolve the bonding resin. The pad has a built‑in thermal wear indicator: if you observe reddish dust on the wheel rim, schedule inspection immediately. Authentic AZ9231340068 pads show minimal edge cracking even after heavy use.
Every AZ9231340068 Brake Friction Pad is manufactured under IATF 16949 and ISO 14001 certified facilities. Each batch is subjected to a 5‑point quality check: shear strength test (minimum 25 N/cm²), compressibility test (≤2% under 100 bar), thermal cycling from -40°C to +400°C, friction stability test on a full‑scale inertia dynamometer, and salt spray corrosion resistance (≥240 hours). The pad also meets the strict ECE R90 regulation, meaning official approval for use on public roads in all UNECE member countries. A traceability code is laser‑marked on the backing plate, linking the pad to its raw material certificates.
A Chilean copper mining operator replaced their original brake pads with the AZ9231340068 across 120 haul trucks. After 8 months of rigorous off‑road operation, they reported a 35% reduction in unscheduled brake replacements and eliminated two drum changeouts due to scoring. Another fleet in Norway operating log transporters noted that the AZ9231340068 provided exceptional cold bite at -25°C, reducing stopping distance by 12% compared to the previous supplier. These independent results confirm the pad’s engineering superiority.
Each set of AZ9231340068 brake pads is supplied in a tamper‑proof, moisture‑resistant cardboard box with foam inserts. Inside, you will find four friction pads (two wheels’ worth), a tube of high‑temperature grease, and a multilingual installation sheet. A unique QR code printed on the box directly links to the SINOTRUK Homan authenticity verification portal. Counterfeit pads often use low‑grade glue and softer steel; always verify the holographic seal and the matt finish of the friction material. Genuine AZ9231340068 has a distinctive charcoal grey surface with no glossy spots.
Summary: The SINOTRUK Homan Brake Friction Pad (OEM AZ9231340068 (410 X 160)) delivers unmatched stopping power, long service life, and certified safety for heavy trucks. Upgrade your fleet’s braking system with genuine OEM pads – the global choice for reliability and regulatory compliance.
