SHACMAN F3000/F2000/3000/X3000 Rear Brake Pads DZ9112340063/DZ9112340062
FUNCTION
1. Core Braking Function
Generates powerful braking force through close friction against the rear axle brake drum.
Converts the pneumatic energy of the air brake system into mechanical friction, enabling vehicle deceleration, stopping, and parking brake engagement.
Primarily responsible for the main braking duties of heavy-duty truck rear wheels, making it suitable for high-intensity braking conditions such as heavy loads and long downhill descents.
2. Friction and Performance Function
Provides a stable friction coefficient (typically 0.38–0.42), ensuring rapid braking response and short stopping distances.
Maintains excellent braking performance in high-temperature environments, minimizing brake fade.
Features a dual-thickness design (approx. 17mm when new / wear limit at approx. 12mm) to ensure a consistently effective friction surface over an extended period.
3. Safety Assurance Function
Installed within the rear axle drum brake assembly, working in conjunction with components such as brake shoes, return springs, and camshafts.
In the event of wear or anomalies, changes in the brake clearance trigger warning signals or affect braking efficiency, alerting the operator to the need for timely replacement.
Utilizes an eco-friendly, non-asbestos formulation to reduce harmful dust emissions, thereby safeguarding both driver and environmental safety.
Working Principle
The driver depresses the brake pedal → a pneumatic pressure signal is generated.
Compressed air enters the rear axle brake chamber, driving the pushrod and the S-camshaft to rotate.
As the S-camshaft rotates, its cam lobes push apart the two brake shoes (DZ9112340062 and DZ9112340063), causing them to expand outward.
The friction linings on the brake shoes press firmly against the inner wall of the rotating brake drum, generating powerful friction.
This friction converts the rotational kinetic energy of the brake drum (and the wheel) into thermal energy, thereby decelerating or stopping the vehicle.
Features: Drum brakes possess a "self-energizing" effect; when the vehicle is moving forward, the friction force further "wedges" the brake shoes against the brake drum, resulting in even stronger braking force.
Advantages
1. Braking Performance Advantages
Stable friction coefficient (approximately 0.38–0.42), ensuring rapid braking response and strong stopping power.
Features a self-energizing drum design, delivering superior braking performance under heavy loads and during downhill operation.
Minimal braking fade at high temperatures, making it ideal for the prolonged, high-intensity braking conditions typical of heavy-duty trucks.
2. Durability and Lifespan Advantages
Utilizes highly wear-resistant semi-metallic or NAO (Non-Asbestos Organic) materials, offering strong resistance to thermal cracking and dust accumulation.
Optimally designed thickness (approx. 17 mm for new pads) ensures a long service life (reaching 80,000–120,000 km under normal operating conditions).
Outstanding wear resistance reduces the frequency of replacements, thereby lowering maintenance costs.
3. Safety and Environmental Advantages
Asbestos-free, eco-friendly formulation minimizes harmful dust emissions, safeguarding driver health and meeting environmental compliance standards.
Perfectly matched with original vehicle brake drums and Hande rear axles, ensuring excellent braking balance and reducing the risk of vehicle deviation.
Superior heat dissipation capabilities minimize thermal fade and enhance overall driving safety.

Daily Maintenance Suggestions
Inspect the braking system every 5,000–10,000 kilometers or once a month.
Key inspection points:
Remaining thickness of the brake linings (new linings are approximately 17 mm thick; replacement is required once they reach their wear limit).
Check the inner surface of the brake drums for cracks, grooves, or signs of overheating.
Remove dust and grit from the brake drums and linings (avoid using a high-pressure water jet for direct rinsing).
Verify that the return springs, S-cams, and slack adjusters operate freely and are free of binding.
Check for proper brake air pressure, and test for any pulling to one side or abnormal noises during braking.
It is recommended to replace the brake pads promptly once their thickness has worn down to 5–7 mm or less.
