In general, brake discs are replaced every two years or 20,000 to 30,000 miles (about 3.).20,000 to 480,000 km).
1.Mileage: Mileage is one of the main factors in brake disc wear. Generally speaking, when the driving range reaches 20,000 to 30,000 miles, the brake discs may wear and deform. However, this number is not absolute, as the usage of individual vehicles will vary.
2.Driving habits: Driving habits are also one of the important factors in the life of brake discs. If you brake hard frequently, brake for long periods of time, or brake frequently on the highway, then the brake discs may wear out faster. In contrast, a smooth ride and proper use of the braking system can extend the life of the brake discs.
3.Quality & Material: The quality and material of brake discs vary greatly from make and model to model, so their service life is not the same. In general, high-quality brake discs usually have a longer lifespan, while low-quality brake discs may need to be replaced more frequently.
1.Brake Disc Wear Indicator: Some cars are equipped with a brake disc wear indicator, which will sound or display a warning light when the brake disc is worn to a certain extent. If your vehicle is equipped with such an indicator, then when it gives a warning, it means that the brake disc needs to be replaced.
2.Brake Disc Thickness: You can ask your professional auto technician or vehicle manufacturer about the minimum thickness requirements for brake discs. Regularly check the thickness of your brake disc and make sure it is within a safe range. If the brake disc has worn out to near or below the minimum standard thickness, then it is recommended to replace it with a new one.
3.Unusual noise or vibration: If you hear unusual noises (such as a sharp screech) or feel noticeable vibrations while braking, this could be a sign that there is a problem with the brake disc. These conditions may indicate that the brake disc surface is uneven, severely worn, or deformed, and needs to be inspected and replaced immediately.
In summary, while the brake disc replacement interval will vary from vehicle to vehicle, it is generally recommended to check it every two years or 20,000 to 30,000 miles and decide whether or not to replace the brake disc based on the actual condition. Timely replacement of brake discs is essential to maintain good braking performance and driving safety.
