【The owner's family car knowledge】Nowadays, the car is not only a simple means of transportation, but also a life partner of many people. Many friends like to play around with cars after work. There are still some friends who don’t know much about cars, but hope to gain more car knowledge through car experience, and use this knowledge to check their cars. In the future, we will continue to bring some car self-check tips. Let’s take a look today. Self-check of brake pads.
Self-inspection tips hope to introduce some simple self-inspection methods within their ability, so that even if the car owner cannot replace or repair by himself, he can understand the vehicle information in a more timely manner. The method of the problem.
Brake pads and brake discs are two parts. This article mainly explains the brake pads. The brake pads need to be replaced regularly, and the brake discs do not need to be replaced in daily use if there is no damage.
When do the brake pads need to be replaced?
Method 1: Look at the thickness
The thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner as the friction continues during use. Professional technicians suggest that when the thickness of the brake pads is only about 1/3 of the original thickness (about 0.5cm), the owner should increase the frequency of self-checks and be ready to replace them at any time. Of course, due to the design of the wheel hub, individual models do not have the conditions for visual inspection and need to remove the tires to complete.
There is a raised mark on both sides of each brake pad. The thickness of this mark is about two or three millimeters. This is also the limit for the thinnest replacement of the brake disc. If the thickness of the brake pad is already parallel to this mark, it must be replaced. Therefore, when the thickness of the brake pads is close to this mark, the owner must observe and prepare at any time, but it is difficult to accurately observe with the naked eye without removing the tires. At present, many models have the indicator handbrake light when the brake pads are too thin. As prompted, it is more convenient than self-checking.
Tips:There is no strict replacement interval for the brake pads according to the vehicle environment and driving habits. Generally, replacement should be considered when driving about 60,000 kilometers. When the brake pads are found to be thin by naked eyes, technicians should be required to check them during maintenance, because there will be errors in naked eyes, and professional repair stations are more rigorous through calipers than naked eyes.
Method 2: Listen to the sound
If the brake is lightly tapped and accompanied by the squeaky sound of "iron rubbing iron", the brake pads must be replaced immediately. Because the limit marks on both sides of the brake pad have directly rubbed the brake disc, it proves that the brake pad has exceeded the limit. In this case, when replacing the brake pads, you must cooperate with the inspection of the brake discs. When this sound occurs, the brake discs are often damaged. At this time, even if you replace the new brake pads, the noise cannot be eliminated. In severe cases, you need to replace the brake discs. .
Tips:It is often too late when the sound of the brake is heard, and the brake disc will be more or less damaged at this time. The price of brake discs is much higher than that of brake pads. Therefore, it is recommended that you check the brake pads frequently to avoid damage to the brake discs.
Method 3: Feel the power
When the brake pads become thinner, our braking effect will be affected. At this time, we need to depress the brake pedal deeper to achieve the braking effect that can be achieved by lightly stepping on it. The braking effect in the first half of the journey is obviously weakened. Many people feel that they are The brake becomes soft and it is a bit unable to stop. At this time, check whether the brake pads need to be replaced.
Tips:This method is relatively abstract, and it may be a little unsure based on the feeling, so it is very important to develop a good self-checking habit. In addition, the reduced braking effect will lead to increased brake fluid consumption. Therefore, when replacing the brake pads, check the condition of the brake fluid.
