Should The Brake Pad Be Replaced When The Alarm Light Is On?

As the most important part of safety equipment, the brake pads may not be noticed by consumers. More people just know that regular maintenance is performed on time, and the brake pads are generally what 4S stores say. How long does it take to replace ? In strict compliance with the maintenance manual for the kilometers, it looks that the removed old film is not worn seriously, can it still be used? How long will it last? Does the brakes and noises have anything to do with it? Hummer Brake Pad Manufacturer will tell you next.

Generally, high-end cars have brake pad warning lights. Generally, the line will be alarmed when the wire is worn out, reminding the owner to change the brake pads. Of course! However, it can be delayed appropriately! The replacement cycle of the brake pads and brake discs is not fixed, which depends on the driving conditions of the vehicle, the frequency and intensity of the brake pedal depression by the driver. Generally speaking, the front wheel brake pads have a greater loss than the rear wheels. The service life of the front brake pads is about 30,000 to 50,000 kilometers, and the service life of the rear brake pads is about 100,000 to 150,000 kilometers.

So how thick can the new brake pads be? How thin can the wear limit be? The thickness of new brake pads is generally about 15 mm. With the daily wear of the brakes, when the thickness of the brake pads is only one-third of the new one, the frequency of inspection needs to be increased, and new brake pads are always ready to be replaced. Some BMW Brake Pads have raised small signs on both sides. When the brake pads are flush with it (2-3 mm), it means that the limit is approaching. Manufacturers have stipulated that the thickness must not be less than 1.2 mm. After the thickness of the brake pads is less than 1.2 millimeters, the brake pads wear and peel more quickly. Therefore, current Mercedes-Benz, BMW, Audi and other models generally alert the owner of the brake pads at this time.

Some older vehicle brake pads are not connected to the trip computer, but a small iron plate is installed on the brake pad. When the friction material is worn out, the brake disc will also rub the small iron plate of the alarm when the brake pad is stepped on, and a harsh sound of friction between the metal will be emitted, that is, the signal to replace the brake pad. It is certainly correct to replace the alarm, but if there is another option for the driver who has a good driving level and a fixed driving route. During maintenance, the technician detects that the brake pads are about to reach the end, or the computer has alarmed. Dago will work out a more optimized solution for the fans based on the actual remaining thickness-it will be replaced during the next maintenance or it can still drive for several thousand kilometers. 

Of course, all this depends on the driving habits and leisure time of the owner. If the car is usually uniform speed, there is almost no need to run at high speed, and at the same time, the owner can ensure that there is time to visit the store regularly to check, then you can delay the replacement at this time. Conversely, if there is no time for frequent inspections at the store, then it must be replaced on time. After all, delaying replacement is also under the premise of ensuring safety.

In addition, you can't just change the brake pads and ignore the brake discs. At the same time, there is another point that needs to be considered at the same time: the thickness of the brake discs. If the brake disc is already worn and the edges have exposed the back plate, you must not delay the replacement of the brake pads at this time, because if you do not replace it again, the brake pads can only rub against the brake disc back plate. Movement, bringing great dangers.

The above is the replacement rule of the brake pads introduced by Chevrolet Brake Pad Manufacturer. Hope to help everyone.
