If the friction surface of the disc brake comes into contact with the brake disc, it is usually due to component damage or severe brake pad wear. If the condition improves or the phenomenon disappears when the temperature rises, you can check if there is an issue with the brake fluid. New brake systems or those unused for a period of time are prone to producing abnormal noises, and generally, the more they are used, the better they perform.

I've been riding motorcycles for over ten years, and adjusting the brakes is a fundamental skill. First, identify the type of braking system—for disc brakes, check the travel of the brake lever. If it's too loose, braking performance suffers; if it's too tight, it can lead to premature wear. Try adjusting the screw on the lever until you feel significant braking at about half the travel. Also, inspect the brake pads for wear—if they're less than half their original thickness, replace them. Don’t forget to check the brake fluid level and top it up if low to ensure the system functions properly. The process is simple but crucial for safety—test the brake sensitivity before every ride. It's best to do this when the bike is cold to avoid burning your hands.

When motorcycle brakes have issues, I first check common areas. Loose brakes are frequent, possibly due to aging cables or improper tension adjustment. Use simple tools to tighten drum brake screws or adjust disc brake lever travel. Don't forget to check if brake pads are severely worn—new pads improve performance. If brakes make unusual noises or feel sluggish, air may have entered the hydraulic system, requiring bleeding. I always remind myself to test before riding, ensuring brake effectiveness in a safe area. Too tight increases fuel consumption, too loose is dangerous, so maintaining moderate tension is best. Regular maintenance saves major repair costs.

For brake adjustment, I prioritize assessing the condition. For disc brake systems, adjust the lever travel; for drum brakes, tighten the adjustment knob. Pay attention to brake pad wear level - replacement is a necessary step. Check if the cable is rusted or loose, just spray some lubricant. Maintain sufficient hydraulic fluid to avoid air bubble interference. Safety first - after adjustment, test ride on flat ground for a few laps to confirm. Don't neglect this minor maintenance, as it can extend brake lifespan.
