There are several reasons:

1. It should be that the disc brake is not installed or adjusted properly.

2. The newly replaced disc brake will have disc grinding. The disc brake automatically follows up and cannot be adjusted. It will be fine after running in.

3. It mainly depends on whether it is easy to turn the wheel by hand. It is because of the burrs on the brake pads. It is normal for a new car to have friction sounds at the beginning. After half a month of running-in, it will be fine. As long as there are no brakes, it will not work. The rule is that the brake stack is not installed correctly.

4. Avoid overcharging. Stop charging when the charger shows that it is fully charged. Do not charge overnight or even for several days. Overcharging will cause the plate active material to harden and fall off, causing water loss and battery deformation. When batteries operate in high temperature seasons, there is mainly the problem of overcharging.

Wheel alignment

Wheel alignment is another major factor in tire health. If the wheels are misaligned in any way, the tires will wear unevenly, often much faster than wheels that are correctly aligned.

If the steering wheel is off-centre, pulls to one side or the other, or deviates much more than usual when driving on a straight highway, it's usually a sign that the truck's wheels are misaligned.
