All values are based on OEM engineering specifications for the AZ9231340070 brake shoe. Minor deviations may occur due to manufacturing tolerances.
The AZ9231340070 shoe features a specially formulated semi-metallic compound that provides stable friction across a wide temperature range, ensuring consistent braking performance.
The friction material is securely bonded to the steel backing plate using advanced adhesive technology, preventing separation even under extreme thermal and mechanical stress.
The steel backing plate is zinc-plated for excellent corrosion resistance, protecting the AZ9231340070 shoe from rust and extending service life in harsh environments.
The lining is precision-ground to the correct arc radius, ensuring full contact with the brake drum for maximum braking efficiency and even wear.
The advanced compound minimizes brake fade and noise, providing a smooth, quiet stopping experience even under heavy loads.
With its durable material and precision engineering, the AZ9231340070 brake shoe delivers long-lasting performance, reducing the frequency of brake replacements and lowering maintenance costs.
The rear brake shoe is a safety-critical component that directly affects stopping distance, stability, and overall vehicle control. Using a counterfeit or substandard shoe can lead to increased stopping distances, brake fade, uneven wear, and even catastrophic brake failure. The genuine AZ9231340070 brake shoe eliminates these risks through OEM-grade materials, precision manufacturing, and rigorous quality testing.
Key benefits of choosing the authentic AZ9231340070 shoe:
Deruna sources the AZ9231340070 rear brake shoe directly from authorized manufacturers, subjecting each unit to a thorough quality inspection. We package each set securely to prevent damage during shipping, so it arrives ready for installation.
Proper installation and regular maintenance are essential to maximize the service life and braking performance of the AZ9231340070 rear brake shoe. Follow these best practices:
Before fitting the new shoes, inspect the brake drum for scoring or out-of-roundness. Also check the return springs, adjusters, and anchor pins for wear.
Clean all brake components with brake cleaner and apply a thin layer of high-temperature brake grease to the contact points of the AZ9231340070 shoe backing plate.
After installation, adjust the brake shoe clearance to the manufacturer’s specification. Follow the SINOTRUK HOWO service manual for the correct procedure.
After installation, perform a bed-in procedure consisting of several moderate stops to condition the lining and ensure optimal friction transfer.
Always refer to the SINOTRUK HOWO service manual for detailed brake system procedures, torque values, and inspection intervals. Regular inspection of the AZ9231340070 shoe lining thickness is essential to maintain safe braking performance.
The AZ9231340070 rear brake shoe is compatible with a wide range of SINOTRUK HOWO heavy-duty trucks and commercial vehicles, including:
For models not listed, cross-reference your original brake shoe part number with AZ9231340070. This shoe is designed to fit SINOTRUK HOWO rear axles with drum brake systems. Please consult your vehicle’s service manual or a qualified technician to confirm compatibility.
