Car owners often report that the brake pads are not wear-resistant, which is actually an early wear phenomenon. The main reasons for this early wear are as follows.
1. The material and structure of poor quality brake discs or drums are easy to cause early wear of brake pads.
2. Because the brake caliper of the brake system is damaged for a long time, the brake does not return to its original position, resulting in excessive wear of the disc and disc due to long-term wear.
3. The material used for the brake pad is not in conformity with the requirements and the design density of the friction layer of the brake pad is not reasonable, which is also one of the reasons for the serious wear of the brake pad.
4. The design area of the original brake pad is small, and it is also the main reason for the serious wear of the brake pad under long-term overspeed driving, frequent braking, overload work and long-term high temperature.
For the above reasons, it is recommended that you use the brake series products, such as discs, calipers and brake pads, which are compatible with your car. The best time to change the brake pad thickness of the disc brake can be checked by stepping on the brake pad, while the brake pad thickness of the drum brake shoe must be checked by pulling the brake shoe out of the brake. However, whether the brake pads on disc brakes or drum brakes, the manufacturer stipulates that their thickness should not be less than 1.2 mm, because all actual measurements show that the brake pads wear and peel faster before or after 1.2 mm. Therefore, the owner should check and replace the brake pads on the brake at this time or before. Generally, under normal driving conditions, the service life of the front brake pads is 30-50000 km, and the service life of the rear brake pads is 120-15000 km. Now the company mainly produces and processes brake discs of various large passenger cars and heavy trucks. It can be processed and customized according to different requirements of customers. Brake disc and brake disc washer products are exported to domestic and foreign markets, and are highly praised by customers.
Precautions before and after brake pad replacement
First of all, check whether the brake pads replaced by the road sweeper are genuine accessories, whether the integrity of the product packaging, anti-counterfeit marks and packaging marks are consistent with the marks on the brake pads, and whether the product model is consistent with the contents of the certificate of conformity. Before lifting the vehicle, the cover containing brake oil should be opened, and the tire screws should be loosened diagonally. If a simple jack is used for support, the jack shall be properly supported and the wheels without changing the brake pads shall be reinforced. Remove the tire, loosen the fastening screws of the clamp body, check the screws and the sliding guide rod of the clamp, remove the sediment and oil dirt on them, and apply lubricating oil for maintenance. Remove the old brake pads and check the wear degree of the brake discs to see if they are grooved and deteriorated. If the brake disc is severely worn, it should be replaced with a new brake disc with a cycle of 80000-120000 km, otherwise the wear of the newly replaced brake disc will be accelerated, and the direction will shake when braking, and the braking force will be calibrated.
It is worth noting that when installing a new brake pad, the inside and outside should be distinguished, and the friction surface of the brake pad should face the brake disc to make the disc fit properly. Install the accessories and fasten the clamp body. Before fastening the tong body, use a tool to push the plug on the tong back into place, so as to install the tong in place. If it is necessary to replace the brake pads on the drum brake, it is recommended to go to a professional repair shop and ask professional personnel to operate to avoid errors.
The tire should be reset after the brake is installed. When installing the tire screw, tighten it diagonally, which is beneficial to protect the tire and brake hub. At the same time, it is also necessary to check whether the wear of the tread and edge is normal. It is better that the left and right wheels can be replaced regularly, which will help to extend the service life of the tire. Now the company mainly produces and processes brake discs of various large passenger cars and heavy trucks. It can be processed and customized according to different requirements of customers. Brake disc and brake disc washer products are exported to domestic and foreign markets, and are highly praised by customers.
