What Causes the Abnormal Noise When Reversing and Braking in Lavida?
4 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.
My Lavida was making clicking noises when reversing the other day, and upon closer inspection, I found the brake pads were completely worn down. Turns out, driving aggressively and slamming on the brakes accelerated the wear of the pad material. After replacing them with new pads and adding brake dust covers to reduce mud and water buildup, the strange noises disappeared. Daily driving habits are crucial—gentle braking and smooth driving extend pad life. When washing the car, pay attention to rinsing the inner wheel brake area to remove rust and prevent noise. Newbies should learn basic knowledge, like checking brake pad thickness through forum-shared videos. If you hear any unusual sounds, don’t push it—pull over immediately to inspect or seek help from a repair shop. Such small issues are often overlooked but can have serious consequences. Keeping track of your car’s condition saves time and effort in the long run.
Reverse braking noise is not only annoying but also hides safety risks. The noise is often triggered by the warning mechanism due to excessive brake pad wear, and severe wear may lead to failure to brake when reversing. In humid environments, rust on the disc-pad contact surface increases friction and noise, which is more easily overlooked during low-speed turns. It is recommended to slow down, drive steadily, and turn on low beams upon hearing any noise, then safely pull over. Schedule an inspection immediately to avoid worsening damage and unnecessary expenses. Regularly park in dry, ventilated spots to prevent moisture and rust. Remember, poor visibility when reversing combined with brake failure most easily leads to collisions with walls, causing minor dents or even serious injuries.
