Dongfeng Fengyun automobile and bus brake pads

1. How long does it take to replace the brake pads?

Brake pads are also called brake pads. In the automobile braking system, the brake pad is the most critical safety component, which plays a decisive role in all braking effects, so a good brake pad is the patron saint of people and automobiles.

Brake pad refers to the friction material fixed on the brake drum or brake disc that rotates with the wheel, in which the friction lining and friction pad bear external pressure and produce friction effect to achieve the purpose of vehicle deceleration. The replacement time period of brake pads and brake discs is not fixed, which depends on the road conditions of the vehicle and the frequency and intensity of the driver's stepping on the brake pedal. Generally, the replacement mileage of conventional brake pads is about 25,000-30,000 kilometers per trip.

Second, the following are some special situations that need attention:

1, novices generally step on the brakes more, and the consumption will be greater.

2. Automatic gear requires more brake pads than manual gear, because automatic gear shifting depends on accelerator pedal and brake pedal.

If you drive in the city, the brake pads will wear out faster than if you drive on the road. Because I often drive in the city, I often have to stop and go, and the brakes will be used more. It may take tens of kilometers to slow down or stop on expressway, so there are relatively few opportunities to use the brakes.

4. For vehicles with large load capacity, the brake pads wear heavily. In the case of deceleration braking at the same speed, the inertia of heavy vehicles is large, and the friction of brake pads requires a large force, so the wear is large.

Generally speaking, in the case of mixed driving (semi-highway and semi-urban area), the brake pads of the front wheels need 60,000-70,000 kilometers.

5. The brake pads of the rear wheels should be more than 654.38+ 10,000 kilometers. Of course, this is not absolute, just a rough estimate. The brake pads on the front wheels wear faster because when braking, the center of gravity of the car will lean forward, and the force borne by the front brakes is greater than that of the rear brakes, with a ratio of about 7: 3. Therefore, the disc heel of the front brake is generally larger than that of the rear brake.

3. What are the tips for brake pad alarm?

1, the driving computer prompts:

A red word "Please check the brake pads" will appear in the general alarm. Then there is an icon, which is a circle surrounded by several dotted brackets. In general, the display is close to the limit and needs to be replaced immediately.

2. Brake pads are provided with alarm sheets:

Some classic car brake pads are not connected to the driving computer, but a small iron piece is installed on the brake pad to give an alarm. When the friction material is worn, the brake disc is not worn by the brake pad, but by the small iron sheet that gives an alarm. At this time, the vehicle will make a harsh "chirp" sound of friction between metals, which is a signal to replace the brake pads.

3. Simple daily self-examination method:

Check whether the brake pads and brake discs are thin. You can use a small flashlight to observe and check. When it is found that the black friction material of the brake pad is worn and the thickness is less than 5 mm, it is necessary to consider replacing it.

4, car feeling:

If you are experienced, you may feel the brakes are soft without brake pads. What about this? It depends on how you feel after driving for many years.

4. What should I do after replacing the brake pads?

When you replace the brake pads, the braking effect is definitely not as good as before, and you will feel that the brakes are soft. At this time, you must step on the brake to eliminate the gap between the brake pad and the brake disc. In addition, the best braking effect can only be achieved after 200 kilometers. The new brake pads must be driven carefully, and be careful not to follow the car too tightly.
