What's in the brake pads? Your safety and security are one. The car needs to do two things more than anything else: stopping and starting, and brake pads on the front-wheel or four-wheel disc brakes ensure that your car stops running when needed. But what's in the brake pads? Why are they so important, and why do we have so many different types?
What are brake pads?
The brake pads will cause friction to stop the vehicle. They are placed in the brake caliper and clamped on the brake rotor in response to the pressure you exert through the brake pedal. Clamping on the rotor will cause friction, which will slow down and stop the rotor, wheels and vehicle. This friction generates heat and "dust", which are small debris on the brake pads that will fall off during braking. Modern mats are usually made of semi-metal or ceramic compounds and have some distinctive features such as grooves and chamfers.
Semi-metal brake pads
The semi-metallic pad is made of 30%-60% metal by weight, and includes other materials such as graphite lubricant. Semi-metal or semi-metal pads are excellent performance in almost any weather conditions and provide a firm braking feel. Because they have many composite varieties, you can find this high-quality brake pads for daily street driving or hard braking. Although semi-metal gaskets are known for their excellent performance and durability, they also generate a lot of dust and are noisier than ceramic gaskets due to the addition of metal.
Ceramic brake pads
Smooth, fine selection of ceramic pad with its relaxed, quiet and durable stopping performance is known. Ceramic pads are made of dense ceramic materials and are favored for their quiet braking and consistent all-round braking performance. Ceramic brake pad produces less dust. Most ceramic dust evaporated by friction with the rotor, and the pad than the semi-metal dusts, dust remaining finer, lighter in color and more easily stick to the wheel. Although the price is slightly higher, but the ceramic pads may be the best choice for everyday driving, but usually not recommended for heavy transport or severe braking. They may also perform poorly in cold temperatures, lack "cold bite" or brake immediately in extreme cold conditions.
What is the chamfer on the brake pad?
The chamfer is the sloped edge of the brake pad. It controls the way the pads apply friction to the rotor and significantly reduces braking noise.
What is the brake pad slot and why is it important?
The groove in the middle of the brake pad generates friction by separating the braking friction force into separate components and creating a small gap for air, dust and heat, thereby improving braking performance.
What are brake pads?
Spacer plate is mounted between the back plate and the caliper pad. The gasket is usually made of multiple layers of steel and rubber to reduce vibrations that often cause braking noise.
Overall
In determining the required brake pad, use the above features to help determine the most suitable for your driving style. If driving in extreme weather or mountainous areas in most cases, or frequently active towing and/or braking, semi-metal brake pads are a good solution. If you want to reduce initiative through quiet braking and cleaner wheels, ceramic brake pads will meet these requirements.
