Brake pads are also called brake pads. In the braking system of a car, the brake pad is the most critical safety part. The quality of all braking effects is determined by the brake pads, so a good brake pad is the protector of people and cars. We need to check the brake pads frequently to see if they need to be replaced.
The replacement time period of the brake pads and brake discs is not fixed, which depends on the road conditions of the vehicle, the frequency and strength of the driver's brake pedal. Generally speaking, the service life of the front brake pads is 30,000 to 50,000 kilometers, and the service life of the rear brake pads is 120,000 to 150,000 kilometers.
The best time to replace the Bus Disc Brake Pads, the thickness of the disc brake pads can be checked by stepping on the brake pads, while the thickness of the brake pads on the drum brake pads is checked by pulling the brake pads from the brake. out.
The structure of the brake pads is roughly divided into: steel backs, conflict blocks, and accessories. The steel back needs to have sufficient strength and can be installed in a matched manner; the collision block mainly consists of the adhesive layer and the collision material (the bottom layer); the accessories mainly include the muffler sheet, the circlip, the alarm or the alarm wire.
We can also check whether the brake pads should be replaced by ourselves every day. The following teaches us a few very simple methods to ensure that we can learn it as soon as possible.
1. see with eyes
Check whether the brake pads and brake discs are thin. You can use a small flashlight to investigate and check. When you find that the black conflict material of the brake pads is almost worn out, and the thickness is less than 5 mm, you should consider replacing them.
2. Feel the power of the brakes
If you are more experienced, you may feel that the brakes are soft when the brake pads are not. This is a feeling that you have to master for many years.
3. Listen to the sound
The brake pads of some old vehicles are not connected to the trip computer, but a small iron plate for alarm is installed on the brake pads. When the conflicting data is almost gone, the brake disc is not the brake pad, but the small iron plate for the alarm. At this time, the vehicle will emit a harsh "chirp" sound, which is the signal to replace the brake pads.
First of all, it is necessary to check whether the replaced brake pads are genuine accessories (that is, the original car accessory products), whether the integrity of the product packaging, the anti-counterfeiting card and the packaging logo are consistent with the logo on the brake pads, and whether the product model is consistent with the content of the certificate.
Replacement process:
Remove the tire, loosen the tightening screws of the pliers body, check the screws and the sliding guide rod of the pliers, remove the sediment and oil on it, and apply lubricating oil for maintenance. Remove the old brake pads and check the wear level of the brake discs and whether they are ditched or bad. Serious wear (one side depth 3mm) should be replaced with a new brake disc.
The tires should be reset after the brakes are installed. When installing the tire screws, tighten them at the corners, which will help protect the tires and brake hubs. At the same time, it is also necessary to check whether the wear condition of the tread and the edge is normal. It is best to replace the left and right wheels regularly, which will help prolong the service life of the tire.
pay attention to:
Also need to check brake fluid. The brake fluid should be replaced and increased regularly. At the same time, it should be ensured that the grade of the brake fluid used is the same as that of the original brake fluid, which is conducive to removing the sludge and dirt in the brake pipeline and making the braking more active. If different grades of brake fluid are mixed and used, chemical changes will occur, and sludge and inorganic salts will be deposited in the brake system, which will block the pipeline over time and cause brake failure. The result is unimaginable. Before driving away from the seat, apply force to the brakes until you feel that the brakes have returned to the strong position, and then you can drive away normally.
