The brake pad is one of the important parts of the brake system
#What are brake pads
Brake pads are also called brake friction pads. In the automobile braking system, the brake pad is the most critical safety part. The brake pad plays a decisive role in all braking effects. A good brake pad is the protector of people and cars
The working principle of braking is mainly to use the friction between the brake pad and the brake disc (drum) and the tire and the ground to convert the kinetic energy of the vehicle into the heat energy after friction and stop the vehicle. If the brakes fail, the consequences will be unimaginable.
Theoretically, the car needs to be replaced every 50000 kilometers. However, in actual vehicles, the replacement time may be advanced or delayed.
#How to judge whether the brake pad needs to be replaced
>>Look at the thickness
Normally, the thickness of the brake pad is about 1.5cm. When the thickness of the front wheel brake pad reaches the limit value of 0.2cm and the thickness of the rear wheel brake pad reaches the limit value of 0.15cm, we need to replace it in time.
There will still be errors in direct observation with the naked eye. Sometimes it is difficult to see the inner brake pad, so it is best to go to the service station and ask the master to help detect it.
>>Listen to the sound
When braking gently, you hear the "creak" metal friction sound, which may be that the brake pad has exceeded the service limit. Be sure to check it as soon as possible.
>>Sensory strength
When the brake pads become thinner, the braking effect will also be affected. You need to step on the brake pedal to a deeper position to achieve the original braking effect. During this period, I feel that the braking effect is obviously attenuated, or I feel that the brake has become soft, or even I can't stop.
