FUNCTION
1. Controlled Service Braking: When the driver depresses the brake pedal, compressed air in the air reservoir is precisely regulated and proportionally distributed to the front and rear brake chambers to achieve vehicle deceleration, braking, and stopping.
2. Dual-Circuit Independent Control: Employing a primary/secondary dual-circuit design, even if one circuit fails, the other can still provide normal braking force, meeting heavy vehicle safety regulations and significantly improving driving safety.
3. Proportional Braking Output: Braking force is proportional to the pedal pressure and travel, achieving a smooth and controllable braking effect and preventing vehicle lock-up, skidding, or loss of control during emergency braking.
4. Rapid Exhaust Function: When the pedal is released, compressed air in the brake chambers is rapidly expelled, allowing for quick brake release and improving vehicle responsiveness and handling.
Advantages:
Excellent response speed and control precision: Brake pressure builds up within 0.3–0.5 seconds after pedal depressing, and rapid venting upon pedal release ensures smooth, shock-free braking, preventing lock-up or skidding.
Long-term use minimizes air leakage, reducing frequent air pump starts, saving fuel, and extending compressor life; dual-circuit independent sealing ensures that even minor leaks in one circuit do not affect overall braking performance.

Maintenance Schedule (Recommended Reference)
| Maintenance Item | Recommended Interval | Operation Content & Standards |
|---|---|---|
| Daily Visual + Auscultation Inspection | Before each departure / Daily | Check valve body and connections for hissing sounds or oil traces; press pedal and listen for abnormalities |
| Leakage Test | Every 5,000–10,000 km | Apply soapy water to joints and check for static/dynamic leaks |
| Brake Performance Road Test | Every 10,000 km | Test brake response, pedal feel, and stopping distance under no-load/heavy-load conditions |
| Air System Drainage | Weekly or every 5,000 km | Open the air reservoir drain valve to release accumulated water and oil (to prevent contamination inside the valve) |
| Comprehensive Inspection (incl. linkage/pedal) | Every 20,000–30,000 km | Check pedal free play, balance spring, and seal wear |
