Frequently asked questions about brake pads
The impact on braking performance after wading?
After wading, there is a layer of water film between the friction plate/shoe and the brake disc/drum, which reduces the friction and affects the braking effect, and the water in the brake drum is not easy to escape. For disc brakes, the impact of this wading on the braking effect will be lower, because the contact area of the disc brake friction plate is small, and it is exposed to the outside and will not retain water droplets. When the wheels are turning, due to the centrifugal force, the water droplets on the brake discs will quickly dissipate. As long as you slam on the brakes after wading, the residual water layer will be removed. But for drum brakes, you must step on the brakes while walking after wading, that is, step on the brakes while stepping on the accelerator. After several times in a row, the water between the brake shoe and the brake drum can be evaporated. And then restore the braking effect.
Why is there noise when braking?
The noise generated during braking is mainly caused by the resonance or mutual interference of the relevant components of the suspension system. However, due to the improper use or deformation of the material of the brake disc, the hardness, porosity, friction characteristics and compression characteristics of the friction plate are unqualified, and the friction plate and brake disc are damp and rusted (it only needs to be braked a few times to recover) , The metal wire in the friction lining formula is too hard, the friction lining wear degree alarm, and the noise or scream caused by mechanical friction lining scraping disc and other reasons.
