Complete front & rear set • High-friction linings • Precision-machined steel shoes • All locking hardware included • ECE R90 certified
The LZ711800004464+051/2 is a complete brake service kit designed for the front and rear drum brake systems of SINOTRUK Howo A7, T7H, and other heavy-duty truck models. This comprehensive kit includes all the components needed for a full brake shoe replacement: the brake shoes themselves, along with all locking devices such as hold-down springs, return springs, adjuster cables, and retaining pins. Its OEM-grade construction precisely matches the original components’ dimensions, lining material, and spring rates, ensuring a perfect fit and seamless integration with the truck’s existing brake system.
The brake shoes are manufactured with high-strength steel pressings and precision-welded reinforcements, providing a rigid foundation for the friction material. The brake linings are made from a high-quality, non-asbestos organic or ceramic composite, selected for its excellent fade resistance, consistent coefficient of friction, and long service life. Each shoe is rigorously tested to ensure it meets or exceeds the stringent safety standards required for commercial vehicle applications.
The locking devices included in the kit are manufactured from durable spring steel and feature corrosion-resistant coatings. These components are critical for maintaining proper shoe-to-drum clearance and ensuring the brake shoes retract fully when the brakes are released. The kit includes all necessary springs, pins, and clips, eliminating the need to source these parts separately and ensuring a complete, reliable brake service.
Common signs of worn brake shoes include squealing or grinding noises during braking, a soft or spongy brake pedal, increased stopping distances, and visible wear on the brake linings. Replacing the shoes and locking devices with the LZ711800004464+051/2 kit restores full braking power, enhances safety, and protects the brake drums and other components from costly damage.
Whether you’re performing scheduled maintenance or addressing a brake performance issue, this kit offers the quality, precision, and reliability that SINOTRUK Howo professionals demand.
The LZ711800004464+051/2 brake shoe and locking device kit is specifically designed for SINOTRUK Howo A7 and T7H series trucks, including popular models such as ZZ4257, ZZ3257, and other variants with the same drum brake configuration. It serves as a direct replacement for the original factory brake shoes and hardware, and is compatible with all axles that use this specific brake drum size and mounting system.
This brake kit is essential for applications involving heavy loads, frequent braking, and demanding operating conditions, such as long-haul transport, construction, mining, and heavy hauling. In these environments, the brake system is subjected to extreme heat and stress, making high-quality friction materials and robust hardware critical for safety and reliability. The LZ711800004464+051/2 kit is engineered to provide consistent stopping power, even under the most severe conditions.
The kit is designed to work with the factory brake drums and hydraulic actuators, ensuring proper clearance and optimal braking force distribution. It is compatible with both standard and heavy-duty axle configurations. When replacing brake shoes, it is highly recommended to inspect the brake drums for scoring or wear and replace them if necessary to ensure the new shoes bed in correctly and deliver maximum stopping power.
For fleets with multiple HOWO trucks, this kit standardizes brake maintenance, simplifying parts inventory and ensuring the correct components are available for scheduled service or emergency repairs. Always verify the axle type and brake drum size on your specific truck to confirm compatibility, though the LZ711800004464+051/2 is the standard brake shoe and locking device kit for the majority of A7 and T7H applications.
Installing the LZ711800004464+051/2 brake shoe and locking device kit is a critical safety procedure that requires mechanical expertise and the proper tools. This work should only be performed by qualified technicians with experience in heavy-duty truck brake systems. Begin by safely raising the vehicle and removing the wheels and brake drums.
Carefully remove the old brake shoe assemblies, taking note of the orientation of the springs, pins, and adjuster cables. Thoroughly clean the brake backing plate and inspect the wheel cylinders for leaks and the brake drums for wear or damage. If the brake drums are scored or worn beyond the manufacturer’s limit, they should be machined or replaced.
Install the new brake shoes from the LZ711800004464+051/2 kit by attaching the parking brake cable and the brake lines. Secure the new brake shoes using the provided hold-down pins and springs. Install the new return springs and the automatic adjuster mechanism, ensuring it is correctly oriented to maintain proper shoe-to-drum clearance.
After installation, adjust the brake shoes to the correct clearance with the drum, then reinstall the brake drum and wheel. Bleed the brake system if any hydraulic lines were opened. Conduct a thorough road test at low speed to ensure the brakes are functioning correctly, making any necessary adjustments to the brake pedal feel and stopping distance. The new brake shoes will require a bedding-in period to achieve optimal performance.
For maintenance, regularly inspect the brake shoes for wear during routine service intervals. Check the thickness of the brake linings and replace them if they are worn down to the manufacturer’s minimum specification. Keep the brake system free of contaminants like oil and grease, which can degrade the friction material. The LZ711800004464+051/2 kit is designed for long service life, but regular inspection is essential for maintaining safe braking performance.
The LZ711800004464+051/2 brake shoe and locking device kit is manufactured in an ISO 9001 and IATF 16949-certified facility using advanced production and quality control processes. The friction material is sourced from leading suppliers and is formulated to deliver consistent, fade-resistant braking performance across a wide range of temperatures.
