Introduction of blake pad

Automobile brake pads are referred to as friction materials that are fixed onto the brake drum or brake disc, which rotates with the wheel. These friction linings and pads bear external pressure and create friction to slow down the vehicle. To gain a better understanding of brake pads, you can refer to the following introduction.

Construction of brake pad

To put it simply, the composition and materials of brake pads for vehicles tend to vary based on several factors including the type, model, and brand of the brake system in question. Generally speaking, such pads contain four main components:

1. A base material that often consists of sturdy metal materials like steel plate or copper alloy, providing durability and strength;

2. A friction material that sits outside of the pad and interacts with the brake disc to produce friction; this component requires high-strength materials that are wear-resistant and possess a high friction coefficient such as carbide metal, ceramic, or organic polymer;

3. Binders, which are chemicals that unify the base material and friction material, improving how well the brake pads perform and last;

4. Anti-noise material that helps decrease noise and vibration during braking, usually achieved via a small soundproof pad or special polymer. Consequently, the efficacy of brake pads largely depends on their materials, shell design, and accuracy of processing, while choice of materials and how one designs brake pads will be influenced by the type of vehicle, brake system, and desired performance.

Principle of brake pad

The principle behind automobile brake pads is based on friction. The brake system of a car involves brake pads, brake discs, brake drums, brake fluid, brake cylinders, and other components. When a driver presses the brake pedal, the brake cylinder generates pressure on the brake fluid, which in turn is transmitted to the brake pads, causing them to rub against the brake discs through friction.

The friction arises due to the brake pad's high friction coefficient. When the brake disc comes into contact with the brake pad, friction generates heat. This heat increases as the friction rises, leading to the temperature of the brake pad to rise to a certain level. When this temperature gets to a particular point, the material of the brake pad undergoes decomposition or sub-chemical reaction, resulting in more heat generation. This process proceeds until the vehicle stops entirely, increasing the braking force and deceleration capacity.

It's crucial to note that proper lubricants are also necessary between the brake pad and the brake disc for lubrication to ensure the adequate functionality of the brake system and improve the brake pad's lifespan. High-speed cars should also avoid prolonged braking, which could overheat the brake pads, leading to brake failure, affecting driving safety.
