The replacement of damaged brake pads seems to be very important. When it is found that the brake pads are worn and need to be replaced, some friends ask if the brake pads need to be replaced together? In fact, they do not need to be replaced together under normal circumstances.

The degree of wear and service life of the front and rear brake pads are often different. Under normal driving conditions, the front brake pads will be subjected to greater braking force, and the degree of wear will often be greater, and the service life will be shorter. Generally, they need to be replaced after about 30,000 to 50,000 kilometers; while the rear brake pads are subjected to less braking force, so they can be used longer, and generally need to be replaced after 60,000 to 100,000 kilometers. When replacing, the coaxial ones must be returned together, so that the braking force on both sides is balanced. If the front, rear, left and right brake pads are worn to a certain extent, four can also be replaced together..

The brake pedal cannot be replaced alone, it is best to replace a pair. If all are worn out, you can consider replacing four. Normally, the front two are replaced together, the back two are replaced together, and the front and rear can be replaced together.

Automobile brake pads are generally replaced every 50,000 kilometers, and the brake shoes are checked every 5,000 kilometers of driving. Not only the thickness of the brake pads should be checked, but also the damage of the brake shoes, whether the damage on both sides is the same, whether it is easy to return to the original position, etc., and any abnormal situation needs to be solved immediately.
