There are several reasons for noise in car brakes, including severely worn brake pads, excessively hard brake pad material, improper installation of the brake system, foreign objects between the brake pads and brake discs, rusted brake calipers, slow return of the brake master cylinder, and the installation of new brake pads. Severe wear of the brake pads is usually caused by the brake pads reaching the warning line or being completely worn out, often resulting in a metallic friction sound. If the brake pad material is too hard, it can easily cause noise. After replacing the original brake pads, noise may occur due to human factors. For example, if the mechanic installed the brake pads incorrectly, upon removal, it may be observed that only part of the brake pad surface shows friction marks, requiring reinstallation.

What Type of Oil Should a China VI Vehicle Use?

China VI vehicles typically use 5W30 semi-synthetic oil. The choice of oil should be based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Always select the oil type recommended in the vehicle's user manual. Owners should opt for multi-grade oil whenever possible, as it offers benefits such as fuel economy, extended lifespan, and high efficiency, providing better protection for the engine. The primary functions of engine oil are to reduce friction and wear on moving parts, remove sludge and varnish from the engine, neutralize acids produced by fuel and lubricant oxidation, improve piston ring sealing, and cool the engine by carrying away heat from moving components.
