What Causes the Squeaking Noise in Polo Brakes?

[McKeira]

The reasons for squeaking noise in Polo brakes are as follows: Use of low-quality or excessively hard brake pads: If low-quality or excessively hard brake pads are used, they will produce a squeaking noise when they rub against the brake disc during braking. Therefore, it is essential to use high-quality brake pads when replacing them. Foreign objects between the brake pads and brake disc: During normal driving, it is inevitable to encounter some complex road conditions. Due to the unique design of disc brakes, sand and other foreign objects may enter between the brake pads and the brake disc, which can also cause unusual noises during braking.

I also encountered brake noise issues when driving my Polo. The main causes could be: brake pads worn to the limit with exposed metal parts scraping against the rotors producing squealing sounds; uneven brake rotor surfaces with grooves requiring resurfacing; sand or small stones trapped causing friction noises; newly replaced brake pads needing several hundred kilometers of break-in period which may temporarily produce occasional noises; cold weather causing material contraction that exacerbates the problem. My recommendation is to immediately check brake pad thickness - replace if below 3mm; simultaneously clean the brake system; don't delay too long to avoid compromising braking performance and increasing accident risks; it's best to have a professional inspection at a repair shop.

As a Polo owner, I was startled by the squeaky brakes last time. After checking, I found it was caused by the brake pads wearing thin, leading to metal friction. Alternatively, new cars might have slight noises during initial use before proper break-in. Another possibility is rust on the brake discs, which is more likely to cause noise on rainy or humid days. Upon noticing the sound, I immediately stopped to inspect. If the noise is continuous, it's a warning sign. Normal operation was restored only after timely replacement of the brake pads. In daily driving, avoid slamming the brakes; gentle operation can reduce abnormal noises. Keep the wheels clean to prevent debris from entering. Safety first—anytime the brakes feel off, address the issue immediately.

I understand the causes of brake noise in Polo, which are mostly due to brake pad material issues or excessive wear; it could also be caused by brake disc deformation or improper installation; regular maintenance can prevent this phenomenon; I check the brake system during every service to ensure there is no dust accumulation; for new brakes, it is recommended to gently press for break-in; if the noise is frequent, it might be a caliper malfunction; early repair can ensure safety.
