Do front and rear brake discs need to be replaced together?

[LaLogan]

No, replacement depends on the thickness of the brake pads. The front pads should be checked after 50,000 kilometers, and they need to be replaced if the thickness is around 3-4mm. The rear pads should be checked around 80,000 kilometers, and replacement is needed if the thickness is 3-4mm. Here is additional information: 1. Car brake pad wear warning light: Most cars are equipped with a brake pad wear warning light, which serves as a reminder for the owner to replace the brake pads early. Those who care for their cars can visit a 4S shop in advance. If you're worried about being misled, check the wear condition when the 4S staff inspects it. If the brake pads are below 5mm, consider replacement. Around 2mm, wear accelerates, marking a dangerous thickness range. It's best to replace them when the light comes on. 2. Regular inspection: Under normal driving conditions, the car's brake pads should be inspected every 5,000 kilometers. Not only should the remaining thickness be checked, but also the wear condition of the pads.
