How long does it take to change the car brake pads

Generally speaking, the service life of the front wheel brake pads is about 40,000 kilometers, and the rear wheel brake pads are about 80,000 kilometers (this is because the center of gravity of the car will lean forward during the brake), and check the brake pads every 5,000 kilometers. But in normal driving, if you encounter these three signs, you need to pay more attention!

1. The thickness of the brake pads

Generally, the thickness of the new brake pads is about 1.5cm. When the brake pad is worn to 0.5cm, it should almost be replaced. There is a protruding logo on both sides of each brake pad. The thickness of this sign is about two or three mm. If the thickness of the brake pads is already parallel to this logo, it must be replaced. Some high -end models will be prompted when the brake film is too thin.

2. Brain abnormal noise

When stepping on the brakes, try to listen to the sound of the brakes. If you hear a sharp sound similar to iron grinding iron, you should pay attention. The extreme logo on both sides of the brake pads has directly rubbed the brake disc, which proves that the brake pads have already been. More than the limit, it must be replaced at this time.

3. Brake response and distance

When the brake pads become thinner, the car's brake response will become slow, and it needs to be deeper and heavier to step on the brakes to achieve the previous braking effect. When you find that the braking effect of the first half of the brakes is significantly weakened, the brakes become soft, and a bit unable to brake, you have to check whether the brake pads need to be replaced.

How to change the brake pads

Because the frequency of each driver's brake is different, it is difficult to define how long the brake pads need to be replaced. The only way is to look at the degree of wear of the brake pads during routine inspections. If you reach the critical point, you must replace it immediately.

The replacement of the brake pads of the disc brake is simpler. Remove the tire and loosen the screws of the brake pliers, you can get the brake pads, and then replace it with a new one. The whole process is up to 5 minutes without any adjustment.

The replacement of the drum -type brake is slightly more difficult. It needs to be removed from the wheels, and then the brake drum is removed before the brake pads. Pay attention to the reassembly between the new brake pads and the brake drum. When assembly, you need to adjust the gap between the brake pads and the brake drum. In short, this is a slightly technical work.

The correct driving method allows the brake pads to live long

When you encounter some problems, you step on the brakes. This is the favorite of people with bad driving skills, but it is actually a hidden danger of accidents. I believe you may have such an experience: the car in front is good, and there is nothing wrong with the road ahead, but people have a inexplicable brakes. This is a typical road killer.

In addition, there are only two options during driving: refueling, step on the brakes. The frequency of stepping on the brake has reached a high level. In fact, such people are not a minority. The result of this is naturally 2-30,000 kilometers, and you have to change the brake pads once.

The correct way of driving is to maintain full attention at any time and look at the six roads. It is found that the problem will be accepted in advance in advance, and it is determined whether to step on the brake according to the changes in the situation. Doing so can not only save gasoline, but also extend the life of the brake pads.
