The difference between brake discs and brake pads, should brake pads and brake discs be replaced together?

The car brake system is a very important thing. It is our safety guarantee when driving. In our daily driving life, we often use brakes. The brakes rely on the friction between the brake disc and the brake pads to reduce the speed and speed. The role of braking. Many friends will confuse the two. They don't know the difference between brake discs and brake pads. Let's take a look.

The difference between brake discs and brake pads

The brake disc is also called the brake disc. As the name suggests, it is a disc-shaped disc made of metal with many air holes. When the car is driving, it will rotate with the tires. The brake caliper clamps the brake disc, which will generate The braking force plays a role in slowing down or stopping. The brake disc has a good braking effect and is easier to maintain than drum brakes.

Brake pads are also called brake pads. They are made of ceramic, metal and carbon fiber. They are installed in the brake calipers. In the brake system of a car, the brake pads are the most critical safety parts. The brake effect is determined by the brake pads. Brake pads are generally composed of steel plates, bonded heat insulation layers and friction blocks. When the brakes are stepped on, they will be squeezed onto the brake disc or brake drum to generate friction, so as to achieve the purpose of vehicle deceleration and braking.

Do brake pads and brake discs need to be replaced together?

Under normal circumstances, 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 3-50000 kilometers, and the rear brake pads need to be replaced once for 6-80000 kilometers. The front brake disc is replaced every 6-80000 kilometers, and the rear brake disc needs to be replaced only about 100000 kilometers. In other words, it is only necessary to replace the brake disc once to replace the brake pads twice. It is best to develop the habit of regular inspection and timely maintenance.

What should I do if the car brake disc is rusty due to rainy days or long-term suspension

The material of the brake disc is mostly cast iron, and it has been exposed for a long time, and the working environment is relatively evil, and it is often tested by ice and fire. If the vehicle is parked for a long time or in a humid environment, some rust will be generated on the surface of the brake disc, and these rust will more or less affect the normal operation of the brake system, so it is necessary for us to consciously clean it up. Please follow the editor to understand what to do if the car brake disc is rusty in rainy days or long-term suspension.

The difference between disc brakes and drum brakes

Disc brakes and drum brakes are two commonly used types of vehicles. The so-called drum brakes are composed of devices that rotate, fix, actuate, and adjust positioning. Among them, it is composed of small parts such as bottom plate, sub-pump, shoe and so on. There are usually also connecting rods, springs, studs, brake drums, etc. Today's drum brakes are generally more common in rear-wheel drive cars.

How to deal with the appearance of grooves in the brake disc

Only the front or only the rear brake disc has grooves due to driving habits and uneven distribution of front and rear brake forces. If only one brake disc has grooves and the others are normal, this situation is usually caused by materials or external forces, then how do we deal with the grooves in the brake disc?
