If the braking distance of the motorcycle exceeds the requirements of the driving manual, remove the brake shoes and check the contact area between the brake shoes and the inner diameter of the motorcycle brake hub. It can use fine file and sandpaper to polish the brake shoe surface, so that the contact area between the shoe surface and the brake hub is not less than 80% of the total area, and keep the brake shoe surface and the hub surface clean without dust.
If the brake system needs to be repaired, the brake shoe surface should be replaced. The minimum allowable thickness of the shoe surface is usually required to be 1.5-2mm. When deep wear marks are found on the inner surface of the brake hub, it is necessary to replace the thickened brake shoe surface after turning.
The normal free stroke of the front brake handle (the change of the outer brake handle) is 10-20 mm, and the free stroke of the rear brake pedal is 20-30 mm. The wheels should be able to turn easily without braking.
When the brake is often used to stop the vehicle (such as downhill), the temperature of the brake system (brake shoes) will be very high, so it is necessary to stop to cool down, otherwise it is easy to burn the brake shoes. When driving in rainy days, the braking distance is reduced after the water seeps through the braking system, which should reduce the speed and drive safely.
Motorcycle braking system is a very important part of a motorcycle, which is related to the safety of the driver. Please pay more attention to your car. If the brake is weak and the braking distance is too long, you should check the brake parts to replace and maintain them!
