General maintenance experts said, before the brake replacement cycle is 30000 km, the replacement cycle after the brakes for 60000 kilometers, but because each driver brake frequency is not the same, so more than 3 years of age of the car, maintain every time to check the brake condition.

If the purchase of brake pads, we should pay attention to the following three points: first, look at the packaging, there is a license number on the regular packaging, specify the friction coefficient, the implementation of standards, etc., while the counterfeit and shoddy products are rough packaging, incomplete information. Secondly, observe the appearance of brake linings, and the brake shoes made of inferior brake pieces have lower cost, which is prone to appear in red material, that is rust, while the quality brake pads are exquisite and the workmanship is excellent. Finally, to check the friction coefficient of brake pads, brake pads are usually manufactured according to the SAE standard, and the FF rating factor is chosen. The coefficient of friction rating of the household car is about 0.35-0.45.
