1. It is recommended to inspect your brake pads every 5,000 kilometers under normal driving conditions. Don’t just check the remaining thickness—also examine the wear pattern. Make sure both sides are wearing evenly, and check if the pads return smoothly. If anything seems abnormal, such as uneven wear or sticking, it should be addressed immediately to avoid potential safety issues.
2. Brake pads typically consist of two main parts: the metal backing plate and the friction material. Never replace only the friction part if it’s worn down. For example, on a Volkswagen Jetta, the new front brake pads have a thickness of 14 mm, and they should be replaced when the total thickness reaches 7 mm. This includes at least 3 mm of metal backing and about 4 mm of friction material. Some vehicles come with a brake pad wear indicator that alerts you through the dashboard when replacement is needed. Once the limit is reached, the pads must be replaced, even if they still seem functional. Continuing to use them can reduce braking performance and compromise your safety.
3. When replacing brake pads, always use original equipment manufacturer (OEM) parts. This ensures optimal contact between the pads and the brake rotors, minimizing wear and maximizing braking efficiency.
4. When installing new brake pads, always use the proper tools to push the caliper piston back into place. Avoid using regular crowbars, as this can damage the caliper guide pins or cause the pads to stick, leading to poor braking performance.
5. After replacing the brake pads, it's important to press the brake pedal several times to eliminate any gap between the pads and the rotor. This prevents the first application from being ineffective, which could lead to an accident. Also, drive cautiously for the first 200 km after installation to allow the new pads to bed in properly. During this period, the braking performance may not be at its best, so stay alert and drive safely.

Piston seal is a kind of seal used to seal between piston and cylinder, usually used in hydraulic system and Pressure system. The piston seal can prevent liquid and gas leakage, and also prevent external impurities from entering the system, thus maintaining the normal operation of the system.
Piston seals can be classified based on their structure and material. According to different structures, piston seals can be divided into unidirectional seals and bidirectional seals. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. According to different materials, piston seals can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, etc.
In hydraulic systems, piston seals are typically used to seal hydraulic cylinders and pumps. The piston seals in hydraulic systems need to have characteristics such as high temperature resistance, corrosion resistance, and wear resistance to ensure long-term stable operation of the system. In Pressure system, piston seals are usually used to seal cylinders and pumps. The piston seals in the Pressure system need to be resistant to high pressure, low temperature, wear and other characteristics to ensure the normal operation of the system.
In addition to hydraulic system and Pressure system, piston seals can also be used in other industrial fields, such as automobile, aviation, machinery, etc. In the automotive industry, piston seals are commonly used in engines to ensure normal engine operation. In the aviation industry, piston seals are commonly used in the hydraulic system of aircraft to ensure normal takeoff, landing, and flight. In the field of machinery, piston seals are commonly used in hydraulic and press machines to ensure the normal operation of the machine.
