Brake discs are also called brake discs. When the car is running, it will rotate with the tires. The brake caliper clamps the brake disc, which will generate braking force to slow down or stop.

The brake pads are also called brake pads, which are installed in the brake calipers. When the brakes are stepped on, they will be squeezed onto the brake discs or brake drums, causing friction to achieve the purpose of vehicle deceleration and braking.

In our daily driving life, we often use brakes, and the brakes rely on the friction between the brake discs and the brake pads to reduce the speed and brake. Many friends will confuse them and do not know the difference between brake discs and brake pads.

As the name suggests, the brake disc is a disc-shaped disc made of metal with many air holes in it. The brake disc has a good braking effect and is easier to maintain than a drum brake. The brake pads are made of ceramic, metal and carbon fiber. In the braking system of automobiles, the brake pads are the most critical safety parts. The quality of the braking effect is determined by the brake pads. The brake pads are generally made of steel plate and bonded heat insulation layer. And the friction block.

Do you want to replace the brake pads and brake discs together?

Under normal circumstances, the brake pads and brake discs do not need to be replaced together. The replacement cycle of brake discs is longer than that of brake pads. Under normal driving conditions, the front brake pads need to be replaced once for 30,000 to 50,000 kilometers, and the rear brake pads need to be replaced once for 60,000 to 80,000 kilometers. The front brake disc is replaced once for 60,000 to 80,000 kilometers, and the rear brake disc needs to be replaced only about 100,000 kilometers. In other words, it is necessary to replace the brake disc once after replacing the brake pads twice, and it is best to develop the habit of regular inspection and timely maintenance.
