Timing and Precautions for Replacing Semi-Metallic Brake Pads

Semi-metal-based friction materials are very stable below the conflict coefficient, without thermal degradation, and have good thermal stability. Semi-metal-based friction material has good wear resistance, and its service life is 3-5 times that of asbestos friction material; it has good conflict performance and stable conflict coefficient under high load. In addition, semi-metal-based friction materials have good thermal conductivity. The temperature gradient is small. Especially suitable for small disc brake products. So do you know the timing and precautions for replacing Semi-metallic Brake pads? Next, let's take a look together. Here are some answers.

Here is the content list:

Timing of replacing Semi-metallic Brake pads.

First, the thickness of Semi-metallic Brake pads is less than the minimum maintenance standard allowed by the vehicle manufacturer. Second, when the wear alarm switch on the brake pad has alarmed. Third, when Semi-metallic Brake pads are contaminated with oil or grease. Fourth, Semi-metallic Brake pads make abnormal noise when braking. Under normal circumstances, if the thickness difference between the two sides of the brake pads on the fixed brake caliper reaches 1.5mm, the brake pads on the floating brake caliper need to be replaced when the thickness difference between the two sides of the brake pads reaches 3.0mm. However, it is impossible to accurately determine whether the brake pads are worn or not through simple appearance observation. It is best to use a ruler to measure the thinnest part of Semi-metallic Brake pads to see if it is within the allowable range.

What should I pay attention to for the newly replaced Semi-metallic Brake pads?

First, when changing Semi-metallic Brake pads, you must pay attention to polishing the corners. Generally, Semi-metallic Brake pads have a chamfered surface reserved at the factory, commonly known as "chamfering". In addition to this "chamfer", the edge position of the entire friction surface needs to be polished. This process is noise matching，because the old brake pads and the brake discs have gone through tens of thousands of kilometers of "lingering", they have formed a certain shape complementarity with each other. The second point is that after changing to Semi-metallic Brake pads, try not to brake heavily, let alone brake quickly. Because the friction surface of the new brake pad is not completely conformed to the surface of the brake disc. The third point is that after replacing the new brake pads, you must pay attention to running-in so that the Semi-metallic Brake pads can achieve a better fit with the brake disc as soon as possible to ensure the braking effect.

The owner needs to be reminded: when replacing Semi-metallic Brake pads, use the same material as the old brake pads as much as possible. Of course, it would be better if the new brake pad material can be made one level higher than the original material. Pay attention to the following principles when replacing brake pads: Try not to use NAO materials to replace Semi-metallic Brake pads. NAO material can replace asbestos material brake pads.
