Good braking is the key to safe driving. seemingly ordinary brake discs need to withstand various environments of cold, hot, dry, and wet conditions, maintain structural stability under high temperatures, and have sufficient friction to provide reliable travel guarantees.

However, inferior brake discs do not have such a "responsibility". The low cost of materials leads to high thermal attenuation and thermal conductivity, which can be accompanied by sparks and strong noise during braking. The service life is short, and the braking distance is about 30% longer. And the low-quality brake discs have not been tested and accepted, with rough workmanship and no after-sales guarantee.
In addition, due to the crude operation of some informal repair shops, rust stains on the contact surface of the flange plate may be ignored during replacement, the sliding rails and dust of the brake disc may not be thoroughly cleaned, and even the front and back of the brake disc may be mistaken. After installation, the sensor wires may not be replaced in a timely manner, which affects the braking effect and service life of the brake disc.

Introduce the hazards of brake pads to everyone:
Poor quality brake pads can increase brake disc wear

Using inferior brake pads can result in uneven scratches on the surface of the brake disc, leading to excessive wear and high "protrusions" at the edges. Under normal circumstances, the braking force is most sufficient when the surface of the brake pad and brake disc is fully fitted. However, due to the impact of scratches, the contact area of the brake disc is reduced. As the brake pad can only compress the most convex point of the brake disc, abnormal noise may occur when the force is uneven.

3. Poor quality brake pads exacerbate the speed of brake oil deterioration
Poor quality brake pads have poor high temperature resistance, and generally experience thermal decay at 200 ℃, which is manifested by a decrease in friction coefficient. At the same time, the heat of the brake pads is transferred to the brake oil through the cylinder piston. High temperatures can have an impact on the braking system.
So inferior brake pads not only wear out quickly themselves, but also cause damage to the brake system. When choosing brake pads, car owners must choose those produced by reputable manufacturers.
