This rear brake drum (OEM QDT3502010-LB) is critical for ensuring safe and predictable deceleration, reducing stopping distances, and minimizing brake fade during prolonged use. Its robust construction and precise internal diameter guarantee uniform contact with brake shoes, ensuring even wear and consistent braking force. The QDT3502010-LB is built to endure the rigors of long-haul transport, off-road operations, and severe environmental exposure, delivering dependable service over thousands of miles.
OEM direct replacement • High-strength grey iron • Optimized cooling fins • Precision-machined friction surface
The QDT3502010-LB Rear Brake Drum is a critical component of the vehicle’s foundation braking system, responsible for converting kinetic energy into heat through friction to slow down and stop the truck safely. It is engineered to replace original equipment drums in SINOTRUK Howo trucks, ensuring optimal braking performance, thermal stability, and durability. This genuine part is built to the highest standards, guaranteeing a perfect fit and reliable operation.
Constructed from high-quality grey iron with a controlled microstructure, the drum offers excellent wear resistance, high thermal conductivity, and resistance to scoring and cracking. The braking surface is precision-ground to a fine finish, providing a consistent coefficient of friction with brake shoes. The drum’s ventilation ribs facilitate airflow, reducing heat accumulation and minimizing the risk of brake fade during repeated heavy braking.
This rear brake drum is essential for maintaining vehicle safety, ensuring short stopping distances and stable braking behavior even when fully loaded. Its robust construction and precise engineering guarantee reliable performance over extended service intervals, meeting the rigorous demands of heavy-duty trucking. It is the direct replacement you can trust to keep your SINOTRUK Howo stopping safely and efficiently.
The QDT3502010-LB Rear Brake Drum is specifically engineered for SINOTRUK Howo heavy-duty trucks, including Howo A7, T7H, T5G, and other models that use this drum size and mounting configuration. It is compatible with both standard and heavy-duty rear axle assemblies, making it the ideal replacement choice for maintaining optimal braking performance.
This brake drum is suitable for a wide range of applications, including long-haul trucking, regional distribution, construction, mining, and agricultural operations. The robust construction and effective heat dissipation ensure reliable braking even under sustained heavy loads, steep grades, and high ambient temperatures.
When replacing, always verify the drum diameter, width, and bolt pattern to ensure a perfect match. The QDT3502010-LB is a direct-fit component that simplifies maintenance and restores original braking performance.
Installing the QDT3502010-LB Rear Brake Drum requires proper lifting equipment, hand tools, and safety precautions. Begin by securing the vehicle on level ground with wheel chocks. Remove the rear wheel and hub assembly, then carefully extract the old brake drum. Inspect the brake shoes, springs, and wheel cylinders for wear and replace as needed.
Clean the axle flange and hub mounting surface thoroughly. Install the new brake drum onto the hub, ensuring it seats evenly and rotates freely without binding. Adjust the brake shoes to achieve the correct clearance between the lining and drum inner surface, following the manufacturer’s specifications. Reinstall the wheel and hub assembly, tighten the lug nuts to the recommended torque, and lower the vehicle.
After installation, perform a road test with moderate braking to bed in the new drum and brake shoes. Avoid aggressive braking for the first 200 miles to allow proper mating of the friction surfaces. Regular maintenance includes periodic inspection of the drum for scoring, cracking, or out-of-roundness. Measure the internal diameter with a brake drum gauge and replace if it exceeds the maximum wear limit.
If any signs of brake judder, reduced stopping power, or unusual noise are observed, inspect the drum and associated components immediately. This drum is built to last, but proper care and timely replacement ensure continued braking safety.
This rear brake drum is manufactured in an ISO 9001-certified foundry, with stringent quality controls applied throughout the casting, machining, and finishing processes. The grey iron composition is spectrometrically analysed to ensure optimal mechanical properties. Every drum is subjected to dimensional inspection, hardness testing, and dynamic balancing to guarantee smooth operation.
Each unit undergoes a rigorous 100% leakage test to verify the integrity of the casting, as well as a runout check to ensure the friction surface is perfectly concentric. We also perform random sample testing for thermal fatigue, brake torque capacity, and wear resistance to confirm that the drum meets OEM durability standards. It is designed to deliver consistent stopping power under the most demanding conditions.
Our commitment to quality ensures reliable, fade-free braking performance, reducing the risk of accidents and extending the service life of the entire braking system. Backed by a comprehensive warranty, this brake drum offers peace of mind for fleet operators and owner-operators.
