It is understood that a family went out for an outing on the weekend. When they encountered a sharp turn, the car could not brake. The owner of the car found that the brake pads were severely worn when he checked the car the previous week. Then he went to an auto parts store to buy brake pads. He chose a low-quality brake pad for him, and he went home to install it. The owner drove the car 600KM in the suburbs every day, and the brake pad was subjected to strong friction, because the low-quality brake pad was not heated, which led to the accident. How do we choose brake pads in our daily life?

1. Check the coefficient of friction of the brake pads

If the friction coefficient of the brake pad is too high or too low, it will affect the braking performance and endanger the life safety of the driver and passengers. Especially during emergency braking during high-speed driving, if the friction coefficient is too low, the brakes will not be sensitive, the braking distance will be prolonged, and the probability of traffic accidents will increase.

If the coefficient of friction is too high, the tire will lock up. According to the SAE standard, the brake friction pad will use the rated coefficient of FF grade, that is, the friction rated coefficient is 0.35~0.45. In addition, according to national standards, the suitable working temperature of brake pads is 100°C~350°C, and when the temperature of inferior brake pads reaches 250°C, the friction coefficient will drop sharply, resulting in brake failure.

2. Observe the appearance of the brake pads

High-quality brake pads are particularly particular about the ratio of materials used in the friction material of the brake pads, and the appearance is full of color, smooth to the touch, not easy to drop dust, and the workmanship is excellent. In order to reduce costs, informal ones are made casually, and a large amount of cheap metal scraps are used in the production. The color may be reddish, and the surface may have oxidized.

3. Look at the thickness of the brake pads

The thickness of a new brake pad is generally about 1.5cm, and the thickness will gradually become thinner with continuous friction during use

4. Look at the steel back of the brake pad

Standard brake pad steel back thickness is 5mm

There are many different brands of brake pads and brake pads of different materials on the market now. How to choose a brake pad that suits you with confidence? Don’t worry, I have selected a good brand of brake pads for JMBM brake pads. It has undergone professional quality inspection and strict material control to maximize the performance of the brake pads. For more information, please visit
