2. Step 2: Install New Brake Lever.

   Slide the new WUXING 115PDD brake lever onto the handlebar. Loosen the adjusting nut on the new brake lever to prepare for cable insertion.
3. Step 3: Connect Brake Cable.

   Insert the brake cable into the adjusting nut of the new lever. Once properly seated, tighten the adjusting nut to secure the cable.

4. Step 4: Adjust Lever Position.

   Adjust the position of the brake lever on the handlebar to a comfortable and ergonomic angle. Use an appropriate tool (e.g., Allen key) to tighten the clamp and lock the lever securely in place.

5. Step 5: Link to Controller.

   Connect the brake lever's electrical cable to the e-bike's controller. Ensure the correct plug type (Waterproof or SM) is used and securely connected. The waterproof plug is typically yellow and 3-pin female, while the SM plug is black. Refer to the video for visual guidance on connecting the appropriate plug type.

After installation, test the brakes to ensure they function correctly and the power cut-off feature is active. The brake lever should return smoothly to its original position after being squeezed.

4. Operating Instructions

The WUXING 115PDD E-Bike Brake Lever operates like a standard bicycle brake lever with the added functionality of a motor power cut-off.

• Braking: Squeeze the brake lever towards the handlebar to engage the brake mechanism.
• Power Cut-Off: When the brake lever is squeezed, the integrated sensor will automatically cut power to the e-bike's motor, preventing accidental acceleration while braking.
• Release: Release the brake lever to disengage the brake and restore power to the motor (if the throttle is engaged).

5. Maintenance

Regular maintenance ensures optimal performance and longevity of your brake levers.

• Cleaning: Keep the brake levers and surrounding areas clean from dirt and debris. Use a damp cloth for cleaning.
• Cable Inspection: Periodically check the brake cables for fraying, rust, or damage. Replace damaged cables immediately.
• Tension Adjustment: Ensure proper brake cable tension. The brake lever should have a firm feel and engage the brakes effectively without excessive slack or stiffness. Adjust the adjusting nut as needed.
• Lubrication: Apply a small amount of bicycle-specific lubricant to the pivot points of the brake lever and where the cable enters the housing to ensure smooth operation.
• Sensor Check: Regularly verify that the power cut-off sensor is functioning correctly by observing if the motor disengages when the brake is applied.

6. Troubleshooting

If you encounter issues with your brake levers, refer to the following common problems and solutions:

• Brakes feel spongy or loose:

  Solution: Check brake cable tension. Tighten the adjusting nut on the brake lever or at the brake caliper/V-brake arms. Inspect cables for stretching or damage.

• Brakes are too stiff or drag:

  Solution: Loosen brake cable tension slightly. Ensure the brake lever pivot points are clean and lubricated. Check for any obstructions in the brake cable housing.
• Power cut-off feature not working:

  Solution: Verify that the electrical connection between the brake lever and the controller is secure and correctly plugged in. Check for any visible damage to the sensor wire or connector. Ensure the brake lever is fully returning to its open position when released.

• Brake lever does not return smoothly:

  Solution: Clean and lubricate the lever's pivot points. Check the brake cable for kinks or damage that might impede smooth movement.
