Do you need to replace 4 pcs of brake pads together?

The brake pads do not need to be replaced together with four, but they cannot be replaced alone. It is best to replace a pair. If all of them are used up, you can consider replacing four. Normally, the first two are replaced together, the last two are replaced together, and the front and back can also be replaced together. Car brake pads are usually replaced every 5000 kilometers, and the brake shoes are checked every 5000 kilometers. Not only is the remaining thickness checked, but also the degree of wear on both sides should be checked to see if they are the same. If any abnormalities are found, immediate action should be taken. Precautions for replacing brake pads: 1. Replace the brake pads provided by the original spare parts, only in this way can the braking effect between the brake pads and brake discs be best and the wear be minimized; 2. When replacing the brake shoes, tools must be used to push the brake wheel cylinder back, and other pry bars cannot be used to forcefully press it back. This can easily cause the brake caliper guide screw to bend, causing the brake pads to become stuck.

The other version does not require four brake pads to be replaced simultaneously, and the wear and service life of the front and rear brake pads are different. Under normal driving conditions, the front brake pads will experience greater braking force, greater wear, and shorter service life. They usually need to be replaced after around 30000 to 50000 kilometers, while the rear brake pads will withstand less braking force and can be used for a longer time. They usually only need to be replaced after 60000 to 100000 kilometers. Brake pads, also known as car brake pads, refer to friction materials fixed to the brake drum or brake disc that rotates with the wheels. The friction lining and pads bear external pressure, producing friction and achieving the purpose of vehicle deceleration.
