What is the warranty period for brake discs?
2 Answers
The warranty period for brake discs is two years. The conditions for replacing brake discs include: 1. The thickness of the brake disc is less than the minimum repair standard allowed by the vehicle manufacturer; 2. The wear indicator on the brake disc contacts the brake disc; 3. The brake disc exhibits abnormal wear or tapered wear. The correct method for replacing brake discs is as follows: 1. Check the degree of wear on the brake disc; 2. Remove the tire to access the car's brake disc; 3. The brake disc is mounted on the front wheel bearing and secured by the brake caliper on the outside. Remove the screws on the brake caliper and take off the caliper; 4. Use a hammer to tap the back of the brake disc while rotating it to remove the old brake disc; 5. Align the holes on the new brake disc with those on the bearing, then gently tap the inside of the brake disc with a hammer to ensure it is fully secured on the bearing; 6. Reinstall the brake caliper in its original position and tighten the fixing screws.
I've been driving for over a decade, and brake discs don't have a fixed expiration date—they wear out like shoes. My compact car is mainly used for commuting in the city, and I typically replace them around 60,000 kilometers on average, but it depends on road conditions and driving habits. If I frequently brake hard or carry heavy loads, they wear out faster. I remember once when the brakes shuddered going downhill, which gave me a scare. The mechanic measured the thickness and said it was insufficient, warning that if the original thickness is halved, it becomes dangerous. There are many influencing factors: dusty dirt roads accelerate wear, braking performance is worse in rainy weather, and mismatched discs and pads can also cause issues. Safety comes first—I always have them check the disc surface during annual maintenance. If it's worn down, I replace it immediately. It's not worth skimping on this to prevent accidents.
