Why do Engine Accessories need to be replaced in pairs?

The reason why a motorcycle can lift heavy objects and keep them hovering is because of its braking function, and the main accessory to achieve the braking function is the Engine Accessories. The motorcycle engine starting plate is located in the internal gear and is circular in shape with a round hole in the middle. It keeps the equipment intermittently stopped at all times to increase lifting safety.

However, as the use time increases, the Engine Accessories will become thinner, and it needs to be replaced at this time. So why does it need to be replaced in pairs?
As an important part of the braking system, the Engine Accessories is located on both sides of the ratchet. It forms a brake by squeezing the Engine Accessories of the Engine Accessories itself and the ratchet. Since it is a squeezing brake, it is natural for both pieces to function at the same time during operation.
The working intensity, Engine Accessories and thickness of these two Engine Accessories are basically the same, so the service life is roughly the same. Therefore, when replacing the Engine Accessories, you must replace both pieces at the same time, even if only one of them is replaced. If the other piece is damaged for some reason, the other piece is intact. Both pieces must be replaced together. This can ensure that the two Engine Accessories work with the same performance and avoid different Engine Accessories and thicknesses from affecting the braking system. security.
