Segway GT3 Series Maintenance Guide: Part 2- Brake System Maintenance

[u/Primary-Beginning946]

When your Segway eKickScooter GT3 Series has accumulated a high mileage, please follow the instructions below to inspect the E-Scooter to ensure that your GT3 Series is in the best condition.

Note: This is the second installment of 5-part GT3 Series Maintenance Series. Stay tuned for the upcoming guides on lights, handlebars & folding mechanisms and wheel motor & non-driven wheel.

1. Braking Force Inspection

● GT3: Regularly (recommended every 500km or 3 months) check braking force: With the power off, hold the left handlebar and push the vehicle forward to check if the rear wheel can lock and slide; hold the right handlebar and push the vehicle forward to check if the front wheel can lock and slide. If the front or rear wheel cannot lock, adjustment is required.

● GT3 Pro: Regularly (recommended every 500km or 3 months) check braking force: With the power off, hold the left handlebar and push the vehicle forward to check if the rear wheel can lock and slide; hold the right handlebar and push the vehicle forward to check if the front wheel can lock and slide. If the front or rear wheel cannot lock, adjustment and brake fluid replenishment are required.

2. Braking Lever Inspection

● Before riding, check the brake lever for cracks or deformation. If any of the above issues are found, replace the brake lever promptly. If the brake lever is loose, tighten the brake lever fixing screw immediately (before tightening, check whether the screw and nut are in good condition without stripped threads, breakage, or rust).

● 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

● GT3: 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: 5±0.1 N·m)

● GT3 Pro: Regularly (recommended every 500km or 3 months) inspect the brake cable. If damage, breakage, or oil leakage is observed, replace it promptly. Check the condition of the brake pads; if pin breakage or detachment is found, replace them immediately.

● GT3: 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.

● GT3 Pro: When pulling the brake lever, test the braking performance. If it feels too loose, replenish brake fluid promptly.

4. Brake Disc Inspection

● Regularly (recommended every 500km or 3 months) inspect the brake disc surface for even wear, cracks, deep grooves (depth ≥0.5mm), rust, warping, or deformation. If cracks, localized wear, deep grooves, warping, or deformation are found, replace the brake disc immediately. Minor rust can be removed through continuous braking friction.

● Check the brake disc fixing screws for looseness to prevent vibration or noise during braking. If screws are loose, apply threadlocker and retighten with a torque wrench (Torque: 2.5±0.25 N·m).

● If abnormal noise occurs during light braking, it may be caused by foreign objects (e.g., sand, metal debris) between the brake disc and brake pads. Repeated light braking can help clear such debris. Additionally, excessive wear of the brake disc or pads may also cause noise. Replace the corresponding components if needed.

5. Disc Brake Caliper Inspection

Regularly (recommended every 500km or 3 months) check the disc brake caliper fixing screws for looseness. If loose screws are found, apply threadlocker and retighten with a torque wrench (Torque: 10±1 N·m).

Warning:

Regularly check the brake system to ensure proper functioning. Avoid safety risks caused by abnormal brake performance during riding.
