1. Strong Stability Under Heavy Load Braking
Specially designed for mining and heavy-duty dump trucks, with high braking torque and stable braking response.
High precision fitting between inner diameter and brake shoes ensures no deviation or shaking during braking.

2. High Temperature Resistance & Anti-Fade Perforce
HT300 material delivers excellent high-temperature stability, resisting deformation and cracking under continuous downhill high-temperature conditions.
Optimized structure improves heat dissipation efficiency, effectively reducing brake fade and ensuring braking safety on long downhill slopes.

3. High Wear Resistance & Long Service Life
Optimized alloy cast iron formula provides superior wear resistance on the friction surface compared with ordinary brake drums.
Service life is significantly longer than general parts under normal heavy-duty working conditions, reducing replacement frequency.

4. Original Factory Size for Direct Replacement
ufactured strictly in accordance with Sinotruk original drawings, with 1:1 matching of mounting holes, spigot and flange dimensions.
No modification is required for installation; it can directly replace the original part WG9970340081.

5. Impact Resistance & Crack Resistance
Thick-wall reinforced structure design offers strong resistance to impact loads in harsh mining road conditions.
Stable casting process minimizes internal stress, preventing failures such as cracks and chipping.

6. Low After-Sales Maintenance Cost
High reliability reduces downtime and maintenance time, suitable for high-intensity operation scenarios such as fleets and mines.
Good universality and a complete aftermarket parts system facilitate bulk procurement and replacement.
