Squeaking reasons: Severe wear of brake pads or brake discs; Issues with the material of brake pads. Here are the related introductions: 1. Audi: Audi, a German luxury car brand, its logo is four interlocking rings. Now a subsidiary of Volkswagen AG, headquartered in Ingolstadt, Germany, with branches in many countries including China. 2.

The new Audi A4L features a completely new exterior and chassis design, with the front and rear of the car resembling the Audi A5.
I've encountered quite a few cases of creaking noises during low-speed braking in my Audi A4L, which are usually caused by friction issues between the brake pads and brake discs. For new cars, the noise may occur due to harder brake pad materials or slight misalignment during installation, resulting in sounds during low-speed friction. In older cars, it's more common to find dust or debris buildup on the brake discs, or uneven wear on the brake pads where some areas are thicker and others thinner, leading to noise. Additionally, rust caused by rain or after washing the car is a frequent factor, and pressing the brakes a few times can usually wear it off. I recommend checking the brake pad thickness; if it's below 3mm, it's time for a replacement. However, don't overlook regular cleaning of the brake components to reduce unusual noises. For safety, whenever you hear such sounds, it's best to visit a 4S shop for a comprehensive inspection to avoid the risk of brake failure.
When driving my friend's A4L, I encountered a similar issue - an annoying creaking sound when braking at low speeds. This was likely caused by dirt on the brake disc surface or small stones stuck between the friction surfaces. Some owners report this also happens when new cars haven't completed the break-in period and the brake pads haven't fully seated. During my inspection, I found it was caused by slight rust, which improved after a few high-speed drives. However, for long-term maintenance, I recommend rinsing the brake discs when washing the car to remove debris and performing regular maintenance to prevent severe wear that could affect braking performance. After all, brake issues are no small matter and should be addressed promptly.
