Did you get your brake pads and brake discs replaced at the 4S shop? How's the quality? I just got mine changed today for 2500 RMB.

The original brake pads damage the disc, wear out easily, produce a lot of dust, and are expensive.

I replaced the front rotors and brake pads at 45,000 kilometers. It seems like I got tricked, but I noticed the rotors have a ridge on the inside and edges. They said if I don't replace the brake rotors, there might be noise.

Did you change both the front and rear wheels?

My old car is 14 years old and the brake discs have never been replaced, even after 200,000 kilometers.

Did you replace both the discs and pads? How many kilometers have you driven?
