The QDT3502070-LB Rear Brake Shoe Assembly is the heart of the drum braking system on the rear axle of FOTON trucks. When the brake pedal is pressed, the wheel cylinder expands, pushing the shoes outward against the rotating brake drum. This friction converts the vehicle’s kinetic energy into heat, effectively slowing or stopping the truck. The assembly designated QDT3502070-LB includes pre-assembled components for quick replacement, minimizing downtime during maintenance.
For commercial vehicles like FOTON trucks, which often operate under heavy loads and in demanding conditions, the integrity of the brake shoes is non-negotiable. The QDT3502070-LB is engineered to withstand high temperatures and pressure without fading or warping. Using a substandard assembly can lead to uneven braking, premature drum wear, and increased risk of failure. Therefore, the genuine QDT3502070-LB part is critical for maintaining the vehicle’s safety certifications and operational legality.
Regular inspection and timely replacement with the QDT3502070-LB assembly prevent more costly damage to brake drums, wheel cylinders, and other related components. It is a direct investment in the safety of the driver, cargo, and other road users, ensuring that the vehicle meets the stringent performance standards expected from FOTON commercial trucks.
High-Friction, Low-Wear Lining: The brake linings on the QDT3502070-LB assembly are formulated from premium materials that provide consistent friction across a wide temperature range. This ensures reliable stopping power from the first application to the thousandth, with minimal wear on the brake drum.
Precision-Formed Shoes & Hardware: The metal shoes in the QDT3502070-LB kit are stamped and formed to exact OEM tolerances. All included springs, pins, and clips are heat-treated for durability, ensuring the assembly operates smoothly and quietly without rattles.
Optimized Heat Dissipation: The design of the QDT3502070-LB assembly facilitates better heat dissipation compared to generic alternatives. This reduces the risk of brake fade during prolonged use, such as descending long grades, which is crucial for truck safety.
Complete Kit for Easy Installation: Each QDT3502070-LB box contains a full set for one axle end (both shoes and all necessary hardware). This completeness eliminates the need to source additional parts, streamlining the repair process and ensuring all components work in harmony.
Beyond these primary features, the QDT3502070-LB assembly is rigorously tested for balance and structural integrity. Vibrations and imbalances are minimized, contributing to a smoother ride and extended tire life. For fleet managers, standardizing on the genuine QDT3502070-LB part simplifies inventory and ensures predictable maintenance outcomes across all vehicles.

The QDT3502070-LB Rear Brake Shoe Assembly is designed for specific FOTON truck models that utilize a 400mm rear drum brake system. These are typically found on light to medium-duty trucks in the Aumark TX series, certain Forland models, and select Ollin series vehicles used for urban distribution, regional freight, and construction support.
This assembly is crucial for vehicles that operate with frequent stop-and-go cycles, such as delivery trucks and refuse collectors. The robust design of the QDT3502070-LB also makes it suitable for trucks that occasionally haul near-maximum capacity, where brake system integrity is under the greatest strain. It is a direct replacement for worn-out original shoes during routine brake servicing.
Using the correct QDT3502070-LB part ensures that the braking force is evenly distributed between the left and right rear wheels, maintaining vehicle stability during braking. Incorrect or mismatched brake shoes can lead to pulling to one side, increased stopping distance, and accelerated wear on other brake components. Therefore, verifying compatibility with the QDT3502070-LB number is a critical step in any brake maintenance procedure.
Installation Overview: Replacing the rear brake shoes with the QDT3502070-LB assembly requires proper tools and safety procedures. The vehicle must be securely lifted and supported. After removing the wheel and brake drum, the old shoes, springs, and hardware are disassembled. The new QDT3502070-LB kit components are then installed in the reverse order, following the manufacturer’s recommended procedure. It is highly advised to replace shoes in axle sets (both left and right) to ensure balanced braking.
Critical Steps: Before installing the QDT3502070-LB assembly, the brake drum’s inner diameter should be measured and machined (if necessary) to ensure it is within service limits and free of grooves. All contact points on the backing plate should be cleaned and lightly lubricated with high-temperature brake grease to ensure smooth shoe movement. The wheel cylinder should be inspected for leaks and its pistons gently pushed back to accommodate the new, thicker shoes of the QDT3502070-LB.
Maintenance Schedule: Brake shoes are wear items and require periodic inspection. It is recommended to check the lining thickness every 20,000 km or during tire rotation. The QDT3502070-LB assembly should be replaced when the lining material wears down to within 2-3 mm of the rivet heads (if riveted). Regular checks for fluid leaks from the wheel cylinder and proper adjustment of the parking brake mechanism are also essential to maximize the life and safety provided by the QDT3502070-LB.
Opting for the authentic QDT3502070-LB Rear Brake Shoe Assembly guarantees performance that matches the original design criteria of FOTON engineers. Aftermarket copies may compromise on material quality, dimensional accuracy, or the durability of included hardware. The genuine QDT3502070-LB is subject to FOTON’s rigorous quality control and testing protocols, ensuring consistent friction characteristics and structural reliability.
From a logistical standpoint, using the documented part number QDT3502070-LB simplifies the procurement process for fleet managers and ensures the correct part is received every time. This reduces the risk of installation errors and comebacks. Furthermore, using genuine parts like QDT3502070-LB helps maintain any existing vehicle warranties and can be a requirement for certain commercial insurance policies.
Economically, while the upfront cost of the QDT3502070-LB might be slightly higher, its longer service life and protection of more expensive components (like brake drums) lead to a lower total cost of ownership. The safety assurance provided by a genuine, tested QDT3502070-LB assembly is invaluable and far outweighs the minimal savings from an unknown alternative.
Each QDT3502070-LB Rear Brake Shoe Assembly is packaged as a complete kit and undergoes final inspection to verify component presence and quality. This product is essential for maintaining the legal and operational safety standards of your FOTON commercial vehicle.
