Routine Maintenance Method of Motorcycle Brake Disc After a long distance ride, the motorcycle brake disc will generate a lot of heat under braking. Therefore, do not wash the motorcycle immediately after a long distance ride. You should turn off the engine to reduce the surface temperature of the brake disc to prevent the brake disc with high temperature from deforming due to thermal expansion and contraction due to contact with cold water. It is also necessary to prevent rocks from hitting the brake disc and causing deformation. If you forget to unlock the wheel rim after locking, you can start the vehicle, which is also easy to cause deformation of the brake disc. When the brake disc is deformed, it will produce a friction sound in a single direction. In addition, the best way to improve the service life of the brake disc is to keep good driving habits and try to avoid sudden stop (easy to increase wear on brake accessories). Clean the mud on the brake disc frequently and check wh…
