What Are the Causes of Metal Friction Noise in the Rear Wheel of a Scooter?

[LeElisa]

Here are the specific reasons for the metal friction noise in the rear wheel of a scooter: Brake clearance adjusted too tightly: The brake clearance is adjusted too tightly, or the brake block return spring is broken. Bearing wear: The rear axle bearing is worn or damaged. Lack of gear oil: The rear wheel gearbox is low on gear oil. It is necessary to inspect and resolve these issues promptly. Below is additional information about scooters: No gears: Scooters do not have gears; they all use continuously variable transmission (CVT). The front brake is on the right handle, while the rear brake can be either a foot brake or a hand brake. If it's a hand brake, it is located on the left handle, similar to a bicycle's brake. Other configurations: The horn is located on the lower left side, and the turn signals are in the middle of the left-hand switch. Turning the switch to either side activates the corresponding turn signal. Generally, the topmost switch is the headlight dimmer switch. If the headlight switch on the right side is turned on, this switch can be used to toggle between high and low beams.
