After the front tire is replaced, the front brake pad and brake disc will make metal friction squeak?
If there's a scream when braking, it's okay! The braking performance is not affected, but the friction sound of brake pads and brake discs is mainly related to the materials of brake pads! Some brake pads have large metal wires or other hard material particles. When the brake pads are worn to these substances, they will make a sound with the brake disc! It will be normal after grinding! Therefore, it is normal and will not affect safety, but the sound is very annoying. If you really can't accept such brake sound, you can also replace the brake pads. Replacing the brake pads with better quality can solve this problem! Precautions for new brake pads: spray carburetor cleaner on the surface of the brake disc during installation, because there is antirust oil on the surface of the new disc, and it is easy to stick oil on the old disc during disassembly. After installing the brake pads, the brake pedal must be pressed several times before starting to ensure that the excessive clearance caused by installation is completely eliminated.
