Does the brake disc have grooves and need to be replaced?
Mar 27,2023
If there are obvious grooves on the brake disc surface, the brake disc usually needs to be replaced. This is because the grooves affect the flatness and friction of the brake disc, thus affecting the performance and safety of the brakes.
Grooves in brake discs are usually caused by wear and tear from long-term use and friction. When obvious grooves appear on the surface of the brake disc, the brake pads will not be able to closely fit the brake disc, thus affecting the friction and braking effect of the brake. At the same time, grooves will also cause the brake disc surface to be uneven, further affecting braking performance and stability.
Some people will also say that the brake discs can be polished, but this is not recommended because polishing may have a negative impact on the performance of the brake discs. Grooves and wear on the surface of the brake disc will reduce the friction coefficient of the brake disc. If the surface of the brake disc is polished by polishing, the friction coefficient of the brake disc may be reduced, and the thickness of the brake disc may be reduced. Thereby reducing braking effect and safety.
In addition, polishing may cause the brake disc to become uneven, causing the brake pads to fail to fit the brake disc surface, affecting the friction and performance of the brake.
Therefore, if there are obvious grooves and wear on the surface of the brake disc, it is recommended to replace it with a new one to ensure the safety and braking performance of the vehicle.
