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.

What Causes Brake Disc Noise?

Brake disc noise can be attributed to the following main reasons: 1. New car or newly replaced brake pads making noise: This is usually due to the new brake discs being harder. Typically, after driving a few hundred kilometers and once the brake pads are properly worn in, the noise will cease. 2. If the vehicle has been owned for many years and has high mileage, and the brake pads are making noise, attention is needed. This is likely because the brake pads have worn too thin. 3. If the car has been parked for a long time without use, or after being left for a few days following rain, you might hear noise from the brake discs when driving again. This situation occurs because rainwater or moisture has entered between the brake pads and discs, causing the brake discs to rust.

How to Reduce Car Noise?

Methods to reduce car noise are as follows: 1. Road noise and tire noise are both structural noises, primarily caused by vibrations. The most effective solution is vibration damping. Adding damping plates combined with sound-absorbing pads can effectively address road noise and tire noise. 2. Wind noise occurs when the pressure of the wind exceeds the sealing resistance of the car doors. Therefore, enhancing the sealing resistance is the most direct and fundamental solution. Door sealing strips and inner sealing strips can effectively resolve this issue. 3. Additionally, specialized damping plates, sound-absorbing pads, and door sealing strips can be used for comprehensive treatment of the fenders, floor, and doors. This approach improves noise levels by addressing the three main sources: vibration damping, sound absorption, and sound insulation.

What does the car air conditioning mode mean?

mode button is located in the air conditioning control area of the center console, which is used to switch the air outlet mode of the car air conditioner, usually switching between modes such as foot blowing, head blowing and windshield blowing. The following is an introduction to other letter markings on the car air conditioner: 1. A/C: The A/C button is the switch of the air conditioning compressor. Only when the compressor is turned on, the air conditioner has the ability to cool. 2. MAX: After the MAX function is activated, the air conditioner in the car will run at full load, and the fan air volume is the largest; this function only appears in some models with automatic air conditioning. After pressing MAX, the air conditioning compressor and fan will use the maximum output to seek to reach the set temperature as soon as possible.

How to Check the Date on Tires?

The last four digits after DOT on the sidewall of a tire indicate the production date. Here is some information about tires: 1. The last four digits of the Tire Identification Number (TIN) represent the production date of the tire. Among these four digits, the last two digits indicate the production year, while the first two digits represent the production week. 2. The general shelf life of car tires is three years. Since tires are mainly made of rubber, and the shelf life of rubber is three years, tires should be replaced every three years.
