DONGFENG TIANLONG Front Brake Slack Adjuster 3551N-010
FUNCTION
1. Transmitting Braking Force: It connects the brake air chamber pushrod to the brake camshaft, transmitting the thrust generated by the air chamber to the camshaft to force the brake shoes outward, thereby achieving vehicle braking.
2. Maintaining Braking Performance: As the brake shoes and drums wear down, it automatically adjusts the clearance to prevent excessive gaps-which could lead to brake lag or insufficient braking force-or insufficient gaps, which could result in brake drag and overheating.
3. Ensuring Driving Safety: It maintains the front axle braking system in its optimal operating condition, minimizes brake pull (deviation), and enhances overall braking stability and safety.
4. Extending Component Lifespan: Proper clearance adjustment reduces abnormal wear on the brake shoes and drums, thereby lowering maintenance frequency.
Advantages
| Category | Specific Performance Advantages |
|---|---|
| Adjustment Accuracy | High-precision worm and worm gear structure allows fine angle adjustment, ensures consistent brake clearance on both sides, and reduces brake pull |
| Force Transmission | High-strength cast steel material with solid structure, reliably transmits thrust from the brake chamber, provides quick response and strong braking force |
| Durability | Surface anti-corrosion treatment offers strong rust resistance, adapts well to harsh conditions (mud, water, salt, high/low temperature), long service life, not prone to sticking |
| Ease of Operation | Manual adjustment design, simple structure, easy and fast to adjust by technicians without complex tools, high maintenance efficiency |
| Cost Performance | Original standard part, perfectly matches Dongfeng front axle, stable and reliable performance, reasonable price, suitable for fleet bulk maintenance |
| Safety | Maintains optimal brake clearance, prevents brake drag, overheating or braking force decay, significantly improves driving safety |
Interfacing Relationships
It is mounted on the outer end of the left brake camshaft on the front axle.
One end fits onto the brake camshaft via a splined bore.
The other end connects to the pushrod of the front left brake chamber via a pushrod fork.
The rotation angle of the camshaft is adjusted through a worm gear mechanism located on the slack adjuster, thereby controlling the clearance of the brake shoes.

Daily Maintenance Suggestions
3551N-010 (Dongfeng Front Axle): Every 10,000 kilometers or during each scheduled maintenance, inspect the slack adjuster for cracks, deformation, or corrosion, and verify that the worm gear rotates freely.
Brake Clearance Inspection: Use a feeler gauge or specialized tool to measure the clearance between the brake shoe and the brake drum, ensuring it falls within the standard range; manually adjust as necessary.
Lubrication Maintenance: Periodically apply high-temperature lithium-based grease to the adjustment bolt and worm gear areas to prevent seizing and corrosion.
Brake Performance Monitoring: Observe the vehicle for signs of brake pull (deviation), delayed braking response, or excessive brake pedal travel; these may indicate a malfunction of the slack adjuster.
