（Por qué las pastillas de freno del automóvil son más propensos a sonidos anormales después de que se instalan nuevas）
When the brake is about to move or the brake is about to stop, the automatic transmission model clanks. This is because an automatic transmission vehicle always generates torque as long as it is in D or R gear. The force is pressed against the brake disc on the drive wheel, and the manual only hears occasional clanging when the slope slackens or the brake is pressed down.
When the brake of the automatic transmission model is half raised, the car has been energized, but the brake disc is still in the half brake state. At this point, there is a lot of friction between the brake liner and the caliper. Make resonant sounds. The brake pads make this sound when reversing. Manual models are usually not required, as there is no need to brake when starting.
Brake pad manufacturer（fábrica de pastillas de freno） inspection method:
Lift the car, then use the tire lever to move the wheels and support arms and check the front suspension lower arm bushing for damage. Determine the wear of the rubber sleeve, if you find damage, please use the wood wedge method, and then test drive to determine whether there is a fault. After replacing conventional factory or brand rubber sleeves, remember to place all four wheels of the vehicle.
There are many possible problems:
1. Produce friction sound between brake disc and brake disc.
2. There is a foreign body between the brake disc and the brake liner.
3. The reason for the quality of brake pads: high metal content or poor quality, friction material is too hard.
4. Protrusion and excessive loneliness in the middle of the brake disc due to irregular or abnormal use time and abnormal contact friction with the (new brake disc).
5. The fixed pin hole of the brake cylinder is naturally worn, and the spring press sheet loses its elasticity. Abnormal sound due to stuck, rusty or inflexible pistons
6. The brake system lacks brake fluid;
7. Abnormal deformation of the brake disc fender, resulting in tight friction with the brake disc in the opposite direction;
Other parts or components are not excluded and are subject to actual vehicle test results. Especially when the cold car is not fully started, the hot car will quickly regress, and the brake is easier to sound. So there are no anomalies. Many different brands of cars are the same, it’s not a problem.
When the brake is abnormal, the car will not vibrate or vibrate, will not feel the inertial balance on both sides of the car, and will not feel that one of the four corners of the car is sinking. None of the above points can rule out that “sound comes from the power of buildings”. If “the sound is coming from an emergency building in the Guan”, then the problem is not only reversing, the car will make an abnormal sound, and will not brake on the speed bump, and the direction will become unstable.
Apart from the abnormal noise, there are no other problems, which means there is no problem with the vehicle itself. We are a brake pad manufacturer Abnormal noise can be eliminated only by checking whether the friction material of the new brake pads（pastillas de freno auto） is hard or not perfectly matched. Of course, if you are unsure of your own judgment, you can check the root cause of the problem several times.
