What is the reason why the brake cylinder does not return?

When installing a vehicle, it is generally necessary to conduct a safety test on the working performance of the brake cylinder to prevent problems during the use of the vehicle. Then we often encounter problems of non-return when using it, then What causes this?
The most frequent problem is that the brake pads are seriously worn. It is necessary to replace the brake pads in time to ensure the good performance of the brake cylinder. Because use will cause wear, the surface flatness of the brake pads has already been inaccurate to a certain extent, so It is necessary to strengthen the maintenance and repair with the old man, and make the correct replacement when necessary.
Our driving habits have caused problems with the brake cylinder. For example, in normal driving, due to the fast rotation of the brake disc, the brake cylinder manufacturer’s superiority will cause the brake pads to be uneven in the hands, but it will cause problems for a long time. The steering wheel will deflect. In this case, the sub-cylinder may need to be replaced.
