How to replace the brake pads?

- Aug 29, 2018 -

When does the brake pad need to be replaced? 

Method 1: Look at the thickness The thickness of a new brake pad is generally around 37.5px, gradually thinning as the friction continues to increase in use. Professional technicians suggest that when the naked eye observes that the thickness of the brake pads is only about 1/3 of the original thickness (about 12.5px), the owner must increase the frequency of self-test and be ready for replacement. Of course, due to the wheel design, individual models do not have the conditions to be viewed by the naked eye and need to be removed to complete the tire. Each brake pad has a raised sign on both sides. The thickness of the mark is about two or three millimeters. This is the limit of the thinnest brake disc replacement. If the brake pad thickness is parallel to this mark, it must be replaced.

Therefore, when the brake pad thickness close to this mark, the owner must always observe the preparation, but it is difficult to accurately observe through the naked eye without disassembling the tire. At present, there are many models in the instrument brake light position when the brake pad is too thin It is suggested that relative self-checking is more convenient. Tips: Brake pads are not subject to a strict replacement interval based on the car environment and driving habits. Generally, you must consider replacing the brake pads when you are driving about 60,000 kilometers. When visually observing that the brake pads are relatively thin, they should be inspected by technicians during maintenance. Because visual observations are inherently inaccurate, professional maintenance stations use calipers to be more rigorous than the naked eye.

 Method 2: Listen to the sound If the brakes are lightly accompanied by the sound of "Iron Iron", the brake pads must be replaced immediately.

Because the limit signs on both sides of the brake pad have directly rubbed the brake disc, it proved that the brake pad has exceeded the limit. In this case, when the brake pads are replaced, they must be checked with the brake discs. When this kind of sound occurs, the brake discs are often damaged. At this time, even if a new brake pad is replaced, the sound cannot be eliminated. If the brake pad is severe, the brake disc must be replaced. . Tip: When you hear the sound of a brake, it is often too late. At this time, the brake disc will be damaged more or less. The price of the brake discs is much higher than that of the brake pads. Therefore, it is recommended that you check the brake pads frequently to avoid damage to the brake pads. Method 3: Feeling of Strength When the brake pads become thinner, our braking effect will be affected. At this time, we need to step deeper on the brake pedal to achieve the braking effect that can be achieved by the previous light stepping. The braking effect in the first half is obviously weakened. Many people feel that their brakes have become soft and a bit unpredictable. At this time, we must check whether the brake pads need to be replaced.
