Common Problems of Brake Friction Plates (1)
Impact on braking performance after wading?
Because there is a layer of water film between the friction plate/shoe and the brake disc/drum after wading, the friction force is reduced, which will affect the braking effect, and the water in the brake drum is not easy to escape. For disc brakes, this wading has a lower impact on the braking effect, because the contact area of the disc brake pads is small, and it is exposed and does not retain water droplets. When the wheel rotates, due to the centrifugal force, the water droplets on the brake disc will quickly dissipate, and the remaining water layer will be removed as long as the brake is slammed a few feet after wading. But for drum brakes, it is necessary to step on the brakes while walking after wading in water, that is, step on the brakes while stepping on the accelerator. After several consecutive times, the water between the brake shoes and the brake drum can be evaporated. This restores the braking effect.
