Automotive brake pads are wearing parts, and with the increase of braking times, brake pads will become thinner and thinner. So, automotive brake pad manufacturers take you to understand how disc brake pads adjust the brake gap?
We know that when braking, the disc brake pads rely on the piston of the brake caliper, push, and then the brake pads and the brake disc friction to achieve braking, then we have not thought, after we release the brake, the brake pads are how to return it, today Shandong brake pad manufacturers and everyone together to study this problem.
When we step on the brake, the piston seal ring will be deformed, when the brake is released, the deformed seal ring will return to its original state, so that the pressure out of the live pull back to achieve the return of the piston and brake pads, so after the caliper is used for a long time, the seal ring will appear aging and insufficient elasticity, which can not be a good return caused by the brake pad drag brake.
After we release the brake, the brake disc is still rotating, and the rotation of the brake disc will push the brake pad away, which is equivalent to help, if it is not easy to understand, you can imagine a scene in life: Both hands hold a relatively thin book, and then quickly pull the book out of it, will push the hands slightly, the brake spiral turn to push the brake pad is such a truth, and the brake spiral speed is faster, push the brake pad force is greater.
Here, the auto brake pad manufacturers have to say that the sealing ring and the automatic adjustment of the brake gap. During the use of brake pads, the gap between brake pads and brake discs will gradually increase due to wear, when the piston seal deformation reaches the limit during braking, the piston can still continue to move forward under the action of liquid pressure until the brake disc is compressed; However, when the brake is removed, the sealing ring can make the distance of the piston return is the same, that is, the gap between the brake pad and the brake disc still maintains the standard value.
Disc brake pads play an important role in the entire automobile brake system, protecting the safety of people and vehicles.
