Tips for simple self-checking of automobile brake pads to eliminate potential safety hazards

Nowadays, in addition to being a simple transportation tool, the car is also a life partner of many people. Many friends like to play with the car and work on it after work. Some friends, even if they don’t understand cars well, want to gain more car knowledge through the use of car experience, and use this knowledge to check their own vehicles. In the future, we will gradually bring some tips for vehicle self-tests. Let’s take a look today Self-test of brake pads.

Self-inspection tips hope to introduce some simple self-inspection methods within its power, so that the owner can learn more about the vehicle information in a timely manner even if he can’t replace or repair it by himself, and can check and judge the vehicle if he can’t get professional inspection at any time. Problem approach.

The brake pad and the brake disc are two parts. This article mainly explains the brake pad. The brake pad needs to be replaced regularly, and the brake disc does not need to be replaced in daily use without damage.

When do 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 is continued during use. Professional technicians suggest that when visually observing 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-tests, ready to replace at any time. Of course, due to the design of the wheels, some models do not have the conditions for visual inspection, and the tires need to be removed to complete.

Each brake pad has a protruding logo on both sides. The thickness of this logo is about two or three millimeters, which is also the limit of the thinnest replacement of the brake disc. If the thickness of the brake pad is already parallel to this logo, it must be replaced. Therefore, when the thickness of the brake pad is close to this mark, the owner must observe and prepare at any time, but it is difficult to accurately observe the naked eye without removing the tire. At present, many models have the position of the instrument hand brake light when the brake pad is too thin It is suggested that it is more convenient for self-checking.

Small suggestion: There is no strict replacement interval for the brake pads according to the car environment and driving habits. Generally, you should consider replacing it when driving for about 60,000 kilometers. When visual observation reveals that the brake pads are thinner, technicians should be required to check them during maintenance, because visual observation will inherently have errors, and professional maintenance stations should be more rigorous than visual observation through calipers.

Method 2: Listen to the sound

If the brake sound is accompanied by the sound of "iron rubbing iron", the brake pads must be replaced immediately. Because the limit marks on both sides of the brake pads have directly rubbed the brake disc, it proves that the brake pads have exceeded the limit. In this case, you must cooperate with the brake disc inspection when replacing the brake pads. When this sound occurs, the brake discs have often been 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. .

Small suggestion: It is often too late when you hear the sound of the brake, and the brake disc will be damaged more or less at this time. The price of the brake disc is much higher than that of the brake pad, so it is recommended that you check the brake pads frequently to avoid damage to the brake disc.

Method 3: Feel the intensity

When the brake pads become thinner, our braking effect will be affected. At this time, we need to press the brake pedal deeper to achieve the braking effect that can be achieved by lightly pressing. The braking effect of the first half of the journey is significantly weakened, and many people feel their own The brakes become soft and can't stop a bit. At this time, check whether the brake pads need to be replaced.

Small suggestion: This method is relatively abstract, and it may be a bit difficult to grasp according to the feeling, so it is very important to develop a good self-check habit. In addition, the reduction of the braking effect will lead to an increase in the consumption of brake fluid, so it is important to check the condition of the brake fluid when replacing the brake pads.
