Practical Guide Brake pads and brake discs: how to choose products suitable for safe driving

Reasonable selection of brake accessories is crucial for driving safety, especially under different road conditions and driving intensities. The adaptability of accessories directly affects braking efficiency. From a material perspective, semi metal brake pads contain 60% -80% metal fibers (such as steel fibers and copper fibers), with a high temperature resistance of up to 600-800 ℃. They are suitable for SUVs or heavy-duty vehicles that frequently run on highways and brake frequently, but the noise during braking is slightly higher and needs to be used with noise reduction pads; Ceramic brake pads are mainly composed of ceramic fibers, which emit more than 70% less dust than semi metallic materials. They have low noise and wear rates, making them more suitable for family cars commuting in cities. However, their low-temperature braking response is slightly slower, and they need to be preheated in advance for use in low-temperature areas in winter. In addition, when selecting, attention should be paid to the diameter and thickness of the brake discs – sedans are usually compatible with brake discs with a diameter of 280-320mm, while SUVs require brake discs with a diameter of 320-380mm. When the brake disc thickness wears down to 2mm below the standard value (such as the original factory thickness of 22mm, which is less than 20mm after wear), it must be replaced. This article will help you accurately match suitable brake accessories based on your car model (such as compact sedans, mid to large SUVs), daily driving conditions (congested roads in cities, highways), and driving habits (mild driving, intense driving). At the same time, it will provide troubleshooting methods for common problems such as brake noise and brake fatigue.
