The importance of automotive brake pads to vehicles is self-evident. When it comes to testing automotive brake pads, the first thing to talk about is the mechanical equipment and standards used in the testing. At present, the national standard for detecting the friction coefficient of brake pads is achieved through a constant speed testing machine. The constant speed testing machine does not test the friction coefficient of brake pads by taking a complete set of brake pads, but by cutting two 25m * 25mm small blocks from the brake pad friction blocks, grinding them flat, and placing them in the designated position of the testing machine. Below, the brake pad manufacturer will take you to learn about the testing methods for brake pads.

How to inspect the brake pads of a car

The rotational speed of the testing machine disk is constant, the ambient temperature is constant, the pressure applied to the friction block is constant, and the sample is a small friction block rather than a complete brake pad. When conducting temperature rise detection in the experiment, the disc at each temperature point rotates at a constant speed of 5000 revolutions, and the average friction coefficient at each temperature point is recorded by the tester; During cooling detection, the testing machine disc rotates at a constant speed of 7500 revolutions, and the testing machine will also record the average friction coefficient at each temperature point.

The above is the knowledge related to brake pad testing introduced to you by the brake pad manufacturer. For more information, please follow the company's official website!
