If you feel that the brake is too tight, use a wrench to loosen the brake arm nut 1 counterclockwise, return the brake cable to shorten the length of the exposed tail, and lock the nut clockwise 1 to confirm the brake force and complete the adjustment.
• Insufficient braking force
If you feel that the brake is too loose, use a wrench to turn the fine adjustment screw 3 counterclockwise, and then confirm the braking force by the brake action, and tighten the limit nut 2 clockwise after completion.
Changing Brake Pads

• Completely loosen the brake cable and remove the brake calipers from the vehicle body with a 4MM hexagon wrench.
• Tilt the tail end of the brake pad return spring and remove it.
• Remove the old brake discs one by one and clean the brake piston with a clean cloth.
• Put the new brake discs in one by one, and push the two brake discs apart with tools.
• Push the return spring to the bottom through the gap of the brake discs.
• Install the calipers to the vehicle body, thread the brake cable and lock it in place.

**Handlebar shaking debugging

**

Check whether the vertical tube screws are loose. If so, fasten the standpipe screws first, and then fasten the two screws of the folding mechanism with a 6mm hexagon wrench.

Use of the extension nozzle
