Many people involve the issue of replacing brake discs and pads when repairing cars, but even if they have their own car, they still cannot distinguish between these two things and always feel that they are the same thing. In fact, the brake disc and brake pad are not the same thing, they need to interact with each other to have a braking effect. Today we will talk about the difference between brake discs and brake pads.
First of all, let's talk about the brake disc. Literally, it should look like a plate. The brake discs mentioned here are generally the four wheel disc brakes or the discs in the front and rear drums provided on the configuration table in the store. The brake disc rotates as the wheels roll, and different structures can be made based on production costs and effects, such as solid discs or brake discs with ventilation openings. In short, it is a rotating disc. And the brake pad can be understood as a sheet shape, because it is indeed much smaller compared to the brake disc. If the brake disc rolls with the wheels, then the brake pad is fixed relative to the longitudinal movement of the vehicle. The only thing that can make it move is that when it needs to brake, it will strike the brake disc horizontally with lightning, realizing the desire of the vehicle to stop.
Finally, the owner can decide whether to replace the brake discs and pads based on abnormal brake sounds, soft brakes, and instrument panel prompts.
