How many kilometers should the Q5 brake pads be replaced?
2 Answers
Q5 brake pads should be replaced at 60,000 kilometers. Brake pads generally consist of two parts: an iron backing plate and friction material. It is important not to wait until the friction material is completely worn out before replacing the pads. Typically, the thickness of a brake pad is 14 millimeters, and the replacement limit thickness is 7 millimeters, which includes over 3 millimeters of iron backing plate thickness and nearly 4 millimeters of friction material thickness. Relevant information is as follows: 1. Automobile brake pads, also known as automobile brake linings, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction block bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. 2. The working principle of brakes mainly comes from friction. By utilizing the friction between the brake pads and the brake disc (drum) as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy after friction, bringing the car to a stop.
Having driven an Audi Q5 for many years, I can say that brake pad replacement intervals shouldn't be rigidly fixed. Generally, it's recommended to inspect and replace them every 40,000 to 60,000 kilometers, as this directly impacts driving safety. Worn brake pads affect braking performance, potentially leading to brake failure during emergency stops at high speeds and causing accidents. Personally, I frequently drive in mountainous areas where wear is accelerated, so I proactively have them checked at professional shops every 30,000 kilometers to ensure immediate replacement when thinning occurs. Don't underestimate this—timely replacement prevents greater risks, such as more expensive repairs if the brake discs get damaged. Developing a habit of regular maintenance saves money and provides peace of mind, after all, life is far more valuable than tire expenses.
