What are the solutions for brake noise in Golf?

Solutions for brake noise in Golf: 1. If it's a screeching sound, first check if the brake pads are nearly worn out (the warning tab is making noise). If the pads are new, check for any foreign objects caught between the brake disc and pads. 2. If it's a dull sound, it's mostly an issue with the brake caliper, such as worn sliding pins or detached spring plates. 3. If it's a hissing sound, there could be multiple issues, including problems with the caliper, brake disc, or brake pads. Therefore, for driving safety, it is recommended to promptly visit a repair shop for inspection and handling if you encounter brake noise. The Golf is a classic compact hatchback family car launched by FAW-Volkswagen. In terms of body dimensions, it measures 4199mm in length, 1786mm in width, and 1479mm in height, with a wheelbase of 2578mm.
I experienced squeaking noises from the front wheels on my Golf 7 and specifically visited three repair shops for diagnosis. When brake pads wear to their limit, the warning metal piece grinds against the brake disc, which is the most common source of abnormal noises. During the last maintenance, severe rust was found on the inner side of the brake disc. The technician said it was due to rust sticking to the brake pads after driving through water, and sanding them down solved the noise. Friends who modify their cars should note that performance brake pads can produce a whistling sound at high temperatures, which is normal and nothing to panic about. If you hear a clunking noise when starting after leaving the car overnight in the rain, it's just surface rust on the brake discs being pushed aside—a few more brake applications will fix it. However, if the steering wheel shakes during hard braking, there's an 80% chance the brake discs are warped and need replacing. My neighbor's Golf had this issue; not replacing them can damage the suspension.
Recently, my colleague's Golf just had its brake squealing issue resolved. Upon disassembly, it was found that the anti-noise shims inside the caliper were completely worn out. Although these components seem insignificant, new brake pads will produce a rattling noise without them. Once, after my car drove through deep water, pebbles got stuck in the wheel hub gaps, creating a grinding sound like a sanding wheel during driving, which was solved by washing the wheel hubs with a water gun. In winter, low temperatures make hard brake pads prone to squealing, especially a common issue with semi-metallic formulas—switching to ceramic formulas can improve this. Reminder to everyone: check if the tire bolts are over-tightened. Once, an apprentice torqued my bolts to 150 Nm, causing the brake discs to make metal stretching noises due to thermal expansion and contraction.
