What are the causes of brake noise in the Audi Q5?
4 Answers
Audi Q5 brake noise is caused by: 1. Corrosion of the brake disc or brake pads; 2. New brake pads; 3. Excessive wear of the brake disc and brake pads; 4. Incorrect installation or mismatched model of brake pads; 5. Use of inferior or overly hard brake pads; 6. Abnormal brake caliper or lack of brake fluid; 7. Presence of foreign objects between the brake drum or disc and the pads. Taking the 2020 Audi Q5 as an example, it belongs to the medium-sized SUV category, with body dimensions of: length 4753mm, width 1893mm, height 1659mm, wheelbase of 2908mm, fuel tank capacity of 73l, and a body weight of 1855kg.
It's quite common to hear squeaking or unusual noises from the brakes of an Audi Q5 while driving, and I often help owners diagnose such issues. The main causes include brake pads worn too thin, triggering the warning indicator to make an alert sound, or rust and dust accumulation on the brake disc surface that hasn’t been cleaned off—especially after rain or prolonged parking. Additionally, small stones, metal shavings, or other debris may get stuck between the brake pads and disc, causing friction. A more troublesome issue is when the brake caliper guide pins lack lubrication or become loose, leading to shaking and unusual noises. Ignoring these problems can not only be annoying but also accelerate brake disc wear, impair braking performance, and even lead to accidents. It’s recommended to drive to an authorized service center as soon as possible for inspection, replacement of brake pads, or cleaning and adjustment of the system to prevent further risks. Regular maintenance, such as checking every 5,000 kilometers, can effectively prevent these issues from occurring.
My Audi Q5 has been making a squealing noise when braking after prolonged use, which is quite concerning. Common causes include worn-out brake pads producing a high-pitched sound or rusted brake discs becoming uneven and causing abnormal friction. Once, after washing the car, I didn’t drive it promptly, and the rust worsened, increasing the noise. Small stones getting lodged in the brake gaps are also a frequent issue, especially after driving on uneven roads. These aren’t just noise problems—they can reduce braking responsiveness and increase stopping distance. During maintenance, it’s advisable to specifically ask the technician to inspect the brake components and replace the pads or discs if necessary. In daily use, try to drive the car promptly in humid seasons to minimize rust buildup. Safety should always come first—don’t skimp on these inspection costs.
The Audi Q5's brakes made strange noises, which scared me several times. The issue often arises from worn-out brake pads or dirt and foreign objects like small sand particles stuck on the brake disc surface. Improper assembly leading to loose guide pins is also common. Taking it to the 4S shop, they can diagnose whether cleaning or replacing parts is needed by checking pad thickness or disc flatness with tools. Delaying the fix might worsen it into a major fault affecting driving, so safety first—don’t delay or panic, just troubleshoot early to avoid bigger issues.
