How to change the thickness of the brake pad?

The importance of the car brake system is well known to everyone. If the car is driving and there is a problem with the brakes, the consequences are very serious. The brake pads of the car are a very important accessory in the brake system. As the use time increases, the brake pads will inevitably wear out, especially when the thickness of the brake pads becomes very thin, the brake performance will be much lower. Then, how to look at the thickness of the Brake Pad, how much does the brake pad thickness need to be replaced ?

The brake pad thickness is lower than the need to replace

A new brake pad thickness is generally around 1.5cm, and the thickness will gradually become thinner during use due to constant friction. Professionals suggest that when the thickness of the brake pads is only about 1/3 of the original thickness (about 0.5 cm), the owner will increase the frequency of the self-test and be ready to replace it. However, some vehicles cannot be judged by clear observation, and you can judge by disassembly. Suggested to find a professional repair shop to check, the disassembly can not be reasonably installed to cause the brakes to fail.

Each brake pad has a raised mark on both sides. The thickness of this mark is about two or three millimeters. This is the limit of the thinnest replacement of the Brake Disc. If the thickness of the brake pad is already parallel with this mark, it must be replaced. Therefore, when the thickness of the brake pad is close to this mark, the owner must observe and prepare at any time, but it is difficult to accurately observe it through the naked eye without disassembling the tire. At present, many models have the position of the hand brake lamp when the brake pad is too thin. Prompt, relative self-test is more convenient.
