What are the causes of brake noise in the Audi Q5?
3 Answers
The causes of brake noise in the Audi Q5 are: 1. Normal activation of ABS; 2. Corrosion of brake pads and brake discs; 3. Excessive wear of brake discs and brake pads; 4. Assembly issues. Taking the 2020 Audi Q5 as an example, it belongs to the mid-size SUV category, with body dimensions of: length 4753mm, width 1893mm, height 1659mm, wheelbase 2908mm, fuel tank capacity 73l, and curb weight 1855kg. The 2020 Audi Q5 features a front suspension with a five-link independent setup and a rear suspension also with a five-link independent setup. It is equipped with a 2.0L turbocharged engine, delivering a maximum horsepower of 190PS, maximum power of 140kW, maximum torque of 320Nm, paired with a 7-speed dual-clutch transmission.
I've been driving an Audi Q5 for several years and often encounter brake noise issues, mainly due to worn brake pads or foreign objects stuck in them. Over time, as the brake pads wear down and become thinner, or when small stones or sand get lodged in them, they can produce squealing sounds during friction. This is more noticeable on rainy days because moisture causes the brake discs to rust, resulting in squeaking noises when braking initially. Newly replaced brake pads may also exhibit this behavior during the break-in period, which is normal. However, if the noise persists and affects braking performance, it's advisable to visit a 4S shop to check for issues like warped brake discs or loose calipers. Regularly cleaning the wheel hubs to reduce dust buildup can help minimize noise. I remember once experiencing loud noises during high-speed braking, but after replacing them with genuine parts, the noise disappeared. Safety should never be taken lightly.
Common causes of brake noise in the Audi Q5 include uneven or rusted brake rotors. Prolonged use can lead to rotor warping or uneven wear, causing noise when rubbing against new pads. Newly installed brake pads may also squeal if the material is incompatible or contains impurities. Loose brake calipers or insufficient lubrication of pins can similarly trigger noise. This is particularly noticeable during short-distance stops after cold starts. It's advisable to check the brake fluid level during inspections, as regular maintenance can prevent serious issues. Using genuine OEM parts enhances reliability and reduces break-in noise. Generally, brake noise doesn't compromise safety, but immediate repair is required if accompanied by soft brake pedal response.
