I know why the brake disc will make a strange noise. Now Xiaobian will tell you how to solve this problem.

    1. one method is to simply change the liner into a different friction material, find a material that takes into account the braking performance, noise, price, etc., change the resonance frequency, and let the gasket and disk do not interact with each other. However, some of the sprays that claim to remove noise should not be used blindly. After all, they directly affect the braking system and keep away from safety hazards.

    2. the other is to check the caliper: whether the guide rail is lubricated smoothly, the piston oil seal has no damage; all the noise proof clips and brake pieces are suitable, the installation is correct; the brake disc is too smooth and is overused.

    3. you can also choose to install the component and remind the replacement of the shim when the brake pad is seriously worn.

    In short, it is worth noting that whenever any parts of the brake are replaced, the foreign bodies and dirt, including some oil stains, must be removed.
