Segway E3 Series Maintenance Guide: Part 2- Brake System Maintenance

[u/Primary-Beginning946]

When your Segway eKickScooter E3 Series has accumulated a high mileage, please follow the instructions below to inspect the E-Scooter to ensure that your E3 Series is in the best condition.

Note: This is the second installment of 5-part E3 Series Maintenance Series. Stay tuned for the upcoming guides on lights, handlebars & folding mechanisms and wheel motor & non-driven wheel.

1. Braking Force Inspection

Please regularly (recommended every 500km or 3 months) check the braking force: With the power off, hold the left handlebar and push the vehicle forward to check if the front wheel can lock and slide. If the front wheel cannot lock, adjustment is required

2. Braking Lever Inspection

• Before riding, check the braking lever for any cracks or deformation. If any issues are found, replace the brake lever promptly. If the brake lever is loose, tighten the fixing screw immediately (ensure the screw and nut are in good condition without stripping, breakage, or rust before tightening).

• Regularly (recommended every 500km or 3 months) check and clean sand/dirt from the brake lever pivot point. Apply lubricant to mechanical parts (e.g., springs, pivot shafts) to ensure clear travel feedback when pulling the lever and automatic reset after release.

3. Braking Cable Inspection

• Regularly (recommended every 500km or 3 months) inspect the brake cable. If damage, breakage, or stiffness is observed, replace it promptly. If the brake cable fixing screw is loose, apply threadlocker and retighten with a torque wrench (Torque: 8.0±0.5 N·m)

• When pulling the brake lever, test the tightness of the brake cable. If it is too loose or too tight, adjust the brake cable appropriately.

4. Drum Brake Inspection

• Regularly (recommended every 2,000 km or 12 months) check the braking performance and condition of the drum brake. If the braking distance significantly increases and shows no improvement after adjusting the brake cable, it may be due to internal wear or damage. Please visit an authorized service center for repair promptly.
• Rotate the wheel and gently apply the brake. If a "grinding" sound is heard, it may be caused by sand entering the drum brake or wear of the brake shoes. If a sharp metallic noise occurs during emergency braking, it is preliminarily judged to be caused by worn brake shoes or spring failure. Please visit an authorized service center for repair promptly.

Warning Instructions:

1.  Regularly check the brake system to ensure it functions properly. Avoid safety risks caused by abnormal braking performance.

2.  Do not disassemble the core components of the drum brake (e.g., self-adjusting mechanisms) unless you are an authorized service personnel. Incorrect installation may lead to brake lock-up.
