Precision-Engineered Friction Material: The 3502N02-085 assembly uses a high-grade, heat-resistant friction compound that provides consistent braking torque across a wide temperature range, resisting fade even during repeated heavy braking.
Robust Steel Backing Plate: The shoe is manufactured from high-strength steel, formed to exact OEM specifications to ensure perfect alignment with the brake drum and cam. It resists bending and distortion under extreme loads.
Precision-Machined Contact Points: Critical areas like the cam roller and anchor pin contact surfaces are accurately machined to minimize wear and ensure smooth, even application of the brakes, reducing the risk of grabbing or pulling.
Corrosion-Resistant Finish: The assembly is protected with a durable e-coat primer and topcoat, providing excellent resistance to rust and corrosion caused by road salt, moisture, and chemicals, ensuring long service life.

Installation of the 3502N02-085 Rear Brake Shoe Assy. should be performed by a qualified technician. Begin by safely supporting the vehicle and removing the wheel and tire. Remove the brake drum. Remove the old shoe assembly by unhooking the return springs and removing the retaining pins and rollers. Clean the backing plate and inspect the camshaft, bushings, and rollers for wear. Position the new 3502N02-085 shoes on the backing plate, install the pins, and hook the return springs using a brake spring tool. Install the cam rollers and ensure they seat properly in the cam. Reinstall the brake drum and adjust the brakes according to the manufacturer’s specifications.
The 3502N02-085 brake shoe assembly is a direct OEM replacement for SINOTRUK HOWO heavy-duty trucks with standard 16-ton rear axles (e.g., ST16, HC16). Compatibility must be verified by matching the part number and axle model with your vehicle’s service manual. Genuine SINOTRUK HOWO parts guarantee a perfect fit with your truck’s original brake hardware, eliminating the need for modification.
Always replace brake shoes in axle sets (both wheels) to ensure balanced braking. Inspect the brake drum for wear or damage and replace if necessary. Apply a thin film of high-temperature brake grease to the shoe contact pads on the backing plate. After installation, check and adjust the brakes before returning the vehicle to service.
The precision‑engineered friction material of the 3502N02-085 provides stable and predictable braking torque, minimizing fade and ensuring reliable stopping power even under heavy loads and repeated use.
High-quality materials and robust construction resist wear, heat checking, and glazing, delivering extended service intervals and lower operating costs.
Pre‑assembled with all necessary hardware (springs, pins, rollers) and manufactured to exact OEM dimensions, the shoe assembly simplifies replacement, reducing labor time and ensuring a correct fit.
Using a genuine OEM brake shoe prevents premature failure and unscheduled brake system repairs, keeping your SINOTRUK HOWO on the road and maximizing productivity.
Worn brake shoes significantly reduce braking efficiency and can lead to unsafe operating conditions. Common indicators include: a scraping or grinding noise during braking, reduced stopping power, a low brake pedal (if the system is self-adjusting), visible thinning of the friction material (lining thickness less than 6 mm), or uneven wear patterns. During routine maintenance, inspect the brake linings through the inspection hole on the backing plate. If the lining is worn close to the rivets or the steel shoe, immediate replacement with a genuine 3502N02-085 Rear Brake Shoe Assy. is essential to restore safe braking performance and prevent damage to the brake drum.
Ignoring worn brake shoes can lead to metal-to-metal contact, scoring the brake drum and requiring expensive replacement. Replacing them promptly with genuine 3502N02-085 ensures your truck’s braking system remains safe and reliable.
To maximize the life of your 3502N02-085 brake shoes, perform regular brake inspections. Check for even lining wear and ensure the automatic slack adjusters are functioning correctly. Keep the brake system clean and free of oil or grease contamination, which can ruin friction materials. During relining, always replace return springs, as weakened springs can cause dragging and accelerated wear. Ensure the brake drums are within manufacturer specifications for diameter and runout. Following these practices will help your braking system perform reliably for hundreds of thousands of kilometers.
Generic aftermarket brake shoes often use inferior friction materials, incorrect profiles, or substandard steel, leading to poor fit, uneven wear, brake fade, and potential brake failure. The genuine SINOTRUK HOWO 3502N02-085 Rear Brake Shoe Assy. is engineered to the exact specifications of your truck’s braking system. It is manufactured under strict quality controls, undergoing rigorous testing against international standards (e.g., ISO, CE) and Sinotruk’s original specs. Using premium, wear-resistant materials ensures it withstands the extreme demands of heavy-duty diesel operation, providing consistent performance and safety.
By choosing the authentic part, you protect your investment and ensure safe, reliable braking for years to come. For fleet managers and owner‑operators who demand the best, the genuine 3502N02-085 is the only responsible choice.
