How to inspect automobile brake pads
1. See thickness
The thickness of a new brake pad is generally about 1.5cm, which will gradually become thinner with the continuous friction in use. Professional technicians suggest that when the thickness of the brake pad is only about 1/3 of the original thickness (about 0.5cm) by visual inspection, the owner should increase the self inspection frequency and be ready to replace it at any time. Of course, due to the wheel hub design, some models do not have the conditions for visual inspection, and the tire needs to be removed to complete.
There is a raised sign on both sides of each brake pad. The thickness of this sign is about twoorthree mm, which is also the limit for replacing the thinnest brake disc. If the thickness of the brake pad has been parallel to this sign, it must be replaced.
Therefore, when the brake pad thickness is close to this sign, the owner should be ready to observe at any time. However, it is difficult to observe accurately with the naked eye without removing the tire. At present, the position of the instrument hand brake light will be prompted when the brake pad is too thin for many models, which is more convenient for self inspection.
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 60000 km. When the brake pad is found to be thin by visual inspection, the technician should be required to check it during maintenance, because there will be errors in visual inspection, and the caliper used by a professional maintenance station is more rigorous than the visual inspection.
2. Listen to the sound
If the sound of "iron rubbing against iron" accompanies the light braking, 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, it is necessary to cooperate with the inspection of the brake disc while replacing the brake pad. When this sound occurs, the brake disc is often damaged. At this time, even if the new brake pad is replaced, the sound cannot be eliminated. In serious cases, the brake disc needs to be replaced.
Tips:
It is often too late to hear the sound of the brake. At this time, the brake disc will be damaged more or less. The price of the brake disc is much higher than that of the brake pad. Therefore, it is recommended that you check the brake pad frequently to avoid damaging the brake disc.
3. Feeling strength
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 in the first half of the journey is significantly weakened. Many people feel that their brakes have become soft and can not be braked. At this time, we need to check whether the brake pads need to be replaced.
Tips:
This method is relatively abstract, which may be difficult to grasp by feeling. Therefore, it is important to develop a good self inspection habit. In addition, the reduction of braking effect will lead to the increase of brake oil consumption. Therefore, when replacing the brake pads, it is necessary to focus on the inspection of the brake oil.
If it is found that the braking efficiency or sensitivity of the hand brake is not ideal, it can usually be solved by adjusting the operating copper cable of the hand brake. There is an adjustable compensation mechanism at the connection between the bottom of the handbrake handle and the copper cable (generally covered by the interior trim). The length of the brake copper cable can be stretched by loosening the locking nut with a wrench.
How often do I change the brake pads
Novices usually step on the brakes more and consume more.
Automatic transmission costs more brake pads than manual transmission, because the shift of automatic transmission depends on the accelerator pedal and brake pedal.
If you drive a car in the city, the brake pad will wear out faster than if you drive a car on the highway. Because I often drive cars in the city, I often have to stop and go, and I use the brakes more often. It may take several tens of kilometers to slow down or stop on the highway, and there are relatively few opportunities to use the brakes.
A car with a heavy load has a large loss of brake pads. When braking at the same speed, the heavy vehicle has a large inertia and requires a large friction force on the brake pads, so the wear is large.
Generally speaking, under mixed driving conditions (half highway and half urban area), the brake pads of the front wheels should be able to use 60000-70000 kilometers.
The brake pads of the rear wheels should be able to use more than 100000 kilometers. Of course, this is not absolute. It's just a rough average. The front brake pads wear out faster because when braking, the center of gravity of the car will tilt forward. The front brake has to bear more force than the rear brake. The ratio is about 7:3. Therefore, the disc heel of the front brake is generally larger than that of the rear brake.
