How to Solve the Piercing Noise from Motorcycle Brakes?

Visit a maintenance service center to grind the edges of the brake pads to avoid friction with the raised edges of the brake disc. Generally, the vehicle's braking system has its own warning system to alert the owner to replace the brake pads. Simply choose to replace the brake disc directly. New brake pads and discs require a break-in period. You can apply some lubricant at the repair shop to reduce the noise.
I've been riding motorcycles for several years, and the issue of squeaky brakes is quite common, usually caused by dust or small debris sticking to the brake pads. Once after riding in the rain, I heard the noise and immediately checked it myself. I found mud and metal shavings stuck to the brake disc. I took it apart, cleaned it with a brush and water, let it dry, and reassembled it—the noise was gone. If the brake pads are severely worn, the sound of metal rubbing will be even more piercing, and that's when you need to replace them. Never ignore rust issues, especially if the bike has been parked outside for a long time—oxidized brake discs can also cause noise when braking. I recommend checking the brake system before and after every ride to keep it clean. If you can't fix it yourself, don't force it—take it to a professional repair shop. Safety comes first, after all, brakes are a matter of life and death. Parking in a dry place can prevent a lot of trouble.
