How to judge that the car brake pads need to be replaced?
As for the various parts of the car, as long as there is damage, it must be replaced in time, otherwise it is very likely to be dangerous when driving, but what makes many car owners feel distressed is not that they don’t want to change it but don’t know when to change it. It is the most suitable time. It would be a pity if the parts can still be used and replaced, but if they are not replaced in time, there may be danger. For example, today I will talk about brake pads. Many people will take a flashlight and look at the brake disc carefully when checking whether to replace the brake pads. Some car owners will step on the brakes for a while to see if the braking distance is exceeded. Standards. In fact, these methods are very troublesome. There is a particularly simple way to determine whether the brake pads need to be replaced, which can be judged by listening to the sound.
If you hear such a sound when you step on the brakes, it is the harsh sound of the interior metal rubbing, and every time you step on the brakes, it will be accompanied by this sound, and this sound sounds like only metal rubbing in the car. Pure sound, it appears when you step on the brake, and there is no when you don't step on it. When you stop outside the car, the sound is sharper, just like the sound of metal scraping against the brake disc, then it means that the brake pads need to be replaced. Some cars think that this situation should be more like the sound of the brake disc being rubbed back and forth between the brake disc and the brake caliper after only a small part of the brake pad has been worn?
Although it is indeed a figure of a metal sheet rubbing against the brake disc, it is not a figure that appears when the brake pad is about to wear out. In fact, the designer deliberately designed this phenomenon when designing. A metal friction strip is inserted at the place where the brake pads are replaced. This metal friction strip is usually useless, and it is basically covered by the brake pads. When the wear of the brake pads reaches the maximum, the brake pads The metal friction strip can no longer be covered, and the friction strip will follow. Therefore, when the brake pads should be replaced, the brake discs will rub against this friction strip, and a sharp sound will be generated to remind the car owner that the brake pads should be replaced.
Some people think that if such a loud noise occurs, the friction strip will not cause great damage to the brake disc? Will the brake disc be damaged by such friction over time? In fact, it will not cause such a result. The metal friction strip has been specially treated, and the brake disc will only have a sharp and louder sound when rubbing against it, but the brake disc will not suffer any wear, and the owner can rest assured. The use of metal friction strips is also a very useful tool for automobiles.
This sharp sound is also deliberately designed by the designer, because some bold car owners do not want to replace the friction plate even if the friction plate is almost worn out and will continue to drive. With this metal friction strip, even if you want to continue to drive, I can’t continue driving, because the shorter the brake pads are, the louder the friction sound will be. If you continue to drive, not only will you be affected, people outside the car can also hear this sound, and no one wants to continue driving. If you want to eliminate this sound, you can only replace a new brake pad.
