Basic Maintenance Tips for the Braking System of a 23-Seat Tourist Vehicle

When the handbrake is not functioning properly, adjust the tension bolts at the connection points of the front and rear handbrake lines.

Regularly check the brake fluid reservoir's level. Refill immediately if the fluid level is below 1/3. The reservoir is typically located in the upper left corner of the dashboard or inside the seat frame.

Brake softness or unresponsive braking requires timely adjustment of the brake clearance and releasing air from the brake lines.

Brake pull can be adjusted by modifying the gap between the brake shoes and brake drums within the braking system.

Regularly inspect the brake line and the fixed points of the chassis, and take protective measures promptly if any detachment or friction between the lines and the chassis is found.

2-6-seater vehicles require regular inspection of the brake line connection for looseness and wear. Adjusting the brakes can be done directly by adjusting the threads on the brake pull rod connected to the brake pedal.

Common Issues and Maintenance for the Rear Axle of a 23-Seat Tour Bus

1. Misalignment of mating cone gears and tooth side clearances, as well as excessive bearing wear in gears, can all cause abnormal noise.

2. Excessive bearing preload, too small gear mesh side clearance, incorrect meshing marks, and insufficient lubricant can all cause abnormal heating. It should be addressed promptly before allowing the vehicle to be dispatched.

3. Regularly inspect the tightness of all connection parts. If loose, tighten immediately to prevent accidents.

4. Regularly inspect for any oil leakage at all connection points, and address any issues promptly.

5. Regularly clean the external soil from the vent plug to maintain air passage. Frequently check the lubricant level; it should not be excessive or insufficient.

6. Squealing noises from the rear axle during vehicle operation are mainly due to the following reasons:

Half-axis bearing damage, replace the bearing.

Insufficient gear oil quantity or prolonged use of gear oil may lead to oil quality degradation. Add gear oil or drain and replace the original gear oil. Inject new gear oil as specified in the manual and the recommended quantity.

Damaged or leaking rear shock absorber, replace with new shock absorber.
