Generally, the thickness of new brake pads is about 1.5cm. When driving and stepping on the brake, the brake pads will gradually become thinner. If the thickness of the brake pads is less than 1cm, the brake pads should be inspected frequently. To be on the safe side, it can be replaced in time. If the thickness of the brake pads is less than 0.5cm, there is a risk of brake failure at any time. The thickness of brake pads can be judged by the naked eye without a caliper.

How to choose brake pads?
1. Look at the materials There are three types of materials for brake pads: semi-metallic, low-metallic and ceramic. Semi-metallic brake pads are the most common and are generally used in ordinary family cars. They are relatively inexpensive. Brake pads with less metal have better performance and are usually installed in mid-range vehicles. Ceramic brake pads have the best performance but are also the most expensive. They are generally used in high-end cars.
2. High-temperature resistance In high-temperature environments, the friction coefficient of brake pads will spread everywhere, affecting the braking effect. So when choosing brake pads, it is essential to check whether the material is stable at 350 degrees.
