What Causes the Abnormal Noise When Reversing and Braking in Lavida?
2 Answers
Lavida reversing and braking abnormal noise may be caused by the following reasons: 1. Normal noise phenomenon: The brake pads are composed of iron plates, graphite, asbestos, etc. When they rub against the brake disc, some metal powder is inevitably produced, which can cause a squeaking noise when braking. If this type of abnormal noise occurs in the brake pads, there is no need to worry too much, as it is a normal noise phenomenon of the brake pads. Firmly pressing the brakes several times or performing emergency braking in an open area can improve this situation. 2. Brake pad wear: Another reason for abnormal braking noise is that the brake pads have worn to their limit. The brake warning piece rubs against the brake disc, producing a metal-on-metal sound. At this point, the braking effectiveness will significantly decrease, posing a serious threat to the driver's safety. It is essential to replace the car's brake pads promptly to prevent any potential danger.
I've been repairing cars for over a decade and have seen many cases of Volkswagen Lavida's reverse braking noise. Most often it's due to severely worn brake pads – when the remaining thickness is less than 3mm, the metal backing plate directly scrapes against the brake disc, creating particularly noticeable friction sounds during low-speed reversing. Moist weather or residual water after car washes can cause disc rusting, resulting in squeaking noises during braking. For new cars, temporary noise may occur during the first few months' break-in period. Loose components like brake caliper brackets can also cause collision noises during rotation. Regularly check brake pad thickness – a simple method is using your phone's flashlight to inspect through the wheel hub gap. Don't wait until the noise worsens to address it, as this might lead to braking failure accidents. It's best to have professional shops conduct comprehensive brake system inspections every six months, while cleaning dust and rust to prevent future issues. Parking in dry garage spaces helps prevent rust effectively.
