Dongfeng School Bus Reminder: Driving Brake Adjustment Please Note
Dongfeng School Bus Reminder: Driving Brake Adjustment Please Note How to adjust the service brake After each 12,000km drive, remove and adjust the service brake, replace the brake shoe or repair and repair the brake drum. Adjustments should be made before loading the wheels, as follows: 1. Make sure the engine brake is turned off before starting the vehicle. 2. When the engine reaches operating temperature, the engine brake switch can be turned on. But at this time, the engine brake will not start working immediately 3. After the engine brake switch is turned on, only when the driver 4. When the driver depresses the clutch pedal or the accelerator pedal, the engine brake will be released immediately. 5. The engine speed has an important influence on the engine braking effect: The higher the engine speed, the better the engine braking effect. Recommendation: In order to achieve the best braking effect, keep the engine speed near the rated speed of 1900-2000 rpm (at the junction of the yellow zone and the red zone). 6. In engine braking mode, the engine stops fuel injection, and the engine speed does not affect fuel consumption. 7. To improve the braking effect, the driver can increase the engine speed by lowering the gear. 8. The engine brake should be used with caution on icy or snowy roads to prevent tires from locking or slipping due to excessive braking power. 10. In the event of an emergency, the driver should depress the brake pedal (ie, the foot of the truck) at the same time. At this time, the braking power will be superimposed and the braking effect will be better. 11. The engine brake is a retarding device, not a parking device. It is not suitable for parking or parking. 12. The engine brake has no damage to the engine and is absolutely safe and reliable. When the engine brake is closed, the normal operating conditions and fuel consumption of the engine are not affected.

1 Release the clutch pedal
2 and release the accelerator pedal
3 and the engine brake will start working when the engine is in gear (not neutral) (three conditions are indispensable)
9. The driver can select the size of the brake power by adjusting the brake gear switch.
Choosing the correct hydraulic cylinder sealing kit can extend the service life of the hydraulic system and improve work efficiency.
The following are some key points for purchasing a hydraulic cylinder sealing kit:
1. Determine the model and specification of the hydraulic cylinder: The size and model of the hydraulic cylinder sealing kit must be completely matched with the hydraulic cylinder, otherwise it may cause poor sealing or damage to the sealing components.
2. Choose appropriate sealing materials: The sealing materials for the hydraulic cylinder sealing kit should be selected based on factors such as the type of hydraulic oil, temperature, pressure, etc. The commonly used sealing materials are fluororubber, Butyl rubber, polyurethane, etc.
3. Choose a reliable supplier: Choose a legitimate hydraulic cylinder sealing kit supplier to ensure product quality and after-sales service.
4. Pay attention to installation and maintenance: Proper installation and maintenance of the hydraulic cylinder sealing kit can extend its service life and reduce maintenance costs.
