How to Deal with Motorcycle Brake Squealing Noise?
3 Answers
Drum brake shoes and the brake drum have oil contamination, causing slipping and producing sharp noises. Rinse the brake drum and brake shoes with alcohol to remove the oil contamination. The surface of the drum brake shoes is too smooth, causing slipping and producing sharp noises. Sand the surface of the brake shoes with 800-grit sandpaper to increase friction.
My own motorcycle used to have brake squealing issues, and dealing with it isn’t actually difficult. First, check the wear condition of the brake pads. If they’re already worn very thin, simply replace them with new ones, as the squealing is often caused by uneven surfaces due to wear, resulting in harsh noise. If the brake pads are still thick but squealing, try spraying Brake Cleaner to clean the brake disc and pad surfaces, removing grease or dust. After cleaning, ride a short distance to see if the noise disappears. If it doesn’t, you may need to sand them down or consider replacing them with higher-quality material if the pads are subpar. Additionally, improper brake installation or rainwater buildup can also cause unusual noises, so check if the mounting bolts are loose and ensure a dry riding environment. During regular maintenance, I routinely clean the brake system and inspect the brake pad condition every three months, which helps prevent issues and saves a lot of trouble.
I'm very concerned about the screeching sound from my motorcycle's brakes, as it directly relates to riding safety. Whenever I hear abnormal noises, I immediately reduce speed and pull over to inspect. The screeching may indicate reduced braking efficiency, increasing risks during emergencies. Common causes include excessively worn brake pads or foreign objects stuck in them, creating noise during friction. I'll check the brake pad thickness and replace them if they're below the safety line, while avoiding DIY adjustments to prevent errors. Next, I'll inspect whether the brake discs are smooth without scratches, and wash them with specialized cleaner if heavily soiled. If the noise persists, I must visit a professional repair shop for inspection, as there might be deeper issues like aging or deformation of the braking system. Remember to pay attention to this warning signal while riding, and maintain the brakes properly to prevent accidents.
