Brake pads are a very important component in the car braking system, directly affecting driving safety. Judging the appearance of brake pads can help us get a preliminary understanding of their condition and whether they need to be replaced in a timely manner.

Firstly, the color of the brake pad’s appearance can provide some clues.

New brake pads are usually shiny and have a smooth appearance. When the brake pads are excessively worn, the surface may turn dark gray or black, which is caused by the high temperature and friction generated during braking. If the surface of the brake pad appears uneven in color, it may indicate a problem with the brake pad and requires careful inspection.

Secondly, the thickness of the brake pad’s surface is also an important indicator for judging its condition.

Generally, the thickness of the brake pad is considered normal within the range specified by the brand. By visually inspecting the appearance of the brake pad, you can roughly estimate whether the thickness of the brake pad is excessively worn. If the brake pad is found to be too thin, it may cause problems such as unstable braking force and longer braking distance, and it needs to be replaced promptly.

In addition, the appearance of the brake pad also reflects its wear condition.

If there are obvious dents, cracks, or damage on the surface of the brake pad, it is a signal that the brake pad needs to be replaced immediately. These damages will seriously affect the performance and service life of the brake pad, and if not replaced in time, it may lead to serious consequences such as brake failure.

Finally, attention should also be paid to the grooves between the brake pad linings.

If the grooves between the brake pad linings are too deep, it may be due to common impurities such as iron slag or oil stains remaining between the brake pad linings. These impurities will affect the contact area of the brake pad, resulting in a decrease in braking effect. At this time, cleaning or replacing the brake pads is necessary.

In conclusion, judging the appearance of brake pads can provide us with clues to get a preliminary understanding of their condition.

However, relying solely on appearance judgment is not enough to fully and objectively evaluate the quality of brake pads. More in-depth inspection and testing should be left to professional personnel. If you have any questions about brake pads, it is recommended to immediately consult and have them inspected at a professional car repair shop or brand dealership to ensure driving safety.
