Por qué no correr a alta velocidad inmediatamente después de cambiar las pastillas de freno）
Many people check brake pads before a long trip, and if they are thin, they will be replaced. This is a good habit and a necessary condition for safe driving. But if you do, it’s very dangerous to run at high speed right away! Because the new braking effect is not good, the braking distance will be long in emergency braking! So why is that? Today, car brake pad manufacturers（proveedores de pastillas de freno） take you to understand!
No surface of an object can be flat, just like plates and plates. In general, only when the contact area of the two reaches 75%, can sufficient braking force be generated to give full play to the braking effect; If the contact area of the two is too small, the friction between them is relatively small when braking, there will be insufficient braking force, and the braking distance of the vehicle will be extended. In general, disc brake systems can achieve close to 100% contact between the disc and the disc, and drum brake systems, which are quite good with 80% of the contact surface.
For the old brake pads and brake discs, the surface marks between the two are consistent due to their long contact and friction. For example, if there is a groove on the brake disc, the corresponding position of the brake pad will be raised; For some reason, the brake disc is partially grounded and then will also be partially grounded. They are almost 100% in contact, ensuring sufficient braking force when braking.
But with a new one, it’s different. The new surface is relatively flat, while the old brake disc surface may not be flat, and the contact area between the two after assembly may be small, some even less than 50%. In this way, when braking, because the contact area is too small, can not produce enough braking force, the braking distance will be extended, and even there is the risk of stopping and not getting off.
First, do not drive at high speed after replacing the brake pads（pastillas de freno auto） of the car.
Someone said my film and plate were new. It should be fine. This is not to say that even new plates and plates will not touch 100% due to machining errors. In addition, the new sheet surface also has an oxide film, which will reduce the coefficient of friction and braking force between the two. So after the new car leaves the factory, the brake system will be run in the operation manual. Generally speaking, after 500 kilometers of driving, the brake disc and the brake disc can reach the ideal running-in and combination state. Please drive carefully during this mileage.
Second, after replacing the new brake pads, what should we do?
1. Drive carefully within 500 kilometers of starting, and keep enough distance between braking and the car in front. During driving, the brake is often lightly stepped on consciously, so that the brake disc and the brake disc often contact friction, so that the surface traces of the two coincide as soon as possible, and the contact surface is larger.
2, find an open space, increase the speed to more than 100 kilometers, and then use moderate strength on the brake, so that the car slowed down until the stop. Repeat this step until the braking distance meets the requirements. During this process, be careful not to overheat the braking system. If you overheat, stop and rest. After the brake system is completely cooled, continue to run in. This method is suitable for long-distance vehicles and can achieve the purpose of fast running-in.
