What Causes the Squeaking Noise When Reversing in a Volkswagen Bora?
2 Answers
There are several main reasons for brake squeaking: 1. Metal hard spots on the brake pads. There may be small metal particles inside the brake pads, which produce a sharp, piercing sound when the brakes are lightly applied. This issue can be resolved by forcefully applying the brakes several times, removing and sanding the brake pads, or replacing them with higher-quality ones. 2. Severe wear on the brake pads triggering the warning system. Brake pads usually have warning indicators. When the pads wear down to their limit, the warning indicator rubs against the brake disc, creating a sharp metal friction sound. At this point, it is crucial to replace the brake pads promptly to avoid damaging the brake disc and potential brake failure.
As a veteran driver with over 20 years of experience who has driven various Volkswagen models including the Bora, brake squeaking during reversing is quite common. This is often caused by surface rust on the brake discs, especially after prolonged parking when humid weather causes iron components to corrode, resulting in that squeaking sound when braking in reverse. But don't panic - usually driving a few kilometers to polish the brake discs will make the noise disappear. If the squeaking occurs frequently, be cautious as it might indicate excessively worn brake pads becoming too thin, or small stones/dust trapped in the braking system causing abnormal friction noise. I recommend regularly checking brake pad thickness to ensure it's within safe limits, otherwise braking performance may be compromised, increasing accident risks. Never underestimate this - safety comes first. If possible, have it inspected at a trusted auto repair shop.
