What are the causes of brake noise in the new Bora?
3 Answers
The brake noise in the new Bora may be due to the brake discs being in the 'break-in' period. Below are the reasons and solutions: 1. Continuous hard braking. The so-called heat fade is essentially the process where excessive use of brakes in a short time causes the brake discs to overheat, thereby reducing braking force. When driving the car with continuous hard braking, heat fade occurs. Two specific manifestations of heat fade are a noticeable decrease in braking force and the appearance of a sharp sound not normally heard during braking, referred to as 'noise.' Both of these are normal occurrences during brake heat fade and do not indicate a brake malfunction. 2. Excessive wear of the brake discs. Not only can excessive wear of the brake pads cause 'strange noises,' but excessive wear of the brake discs can also lead to this issue. When the thickness of the brake discs falls below the critical point, the metal edges enclosing the brake discs come into direct contact with the brake pads, resulting not only in loud abnormal noises but also potential brake failure and severe body vibration. This situation indicates that the brake pads are excessively worn and must be replaced. Failure to replace them not only makes the loud noise unbearable but also leads to a significant drop in braking force, increasing safety hazards.
I've just started driving my new Bora, and I always hear a squeaking sound when braking, which makes me a bit nervous. I asked the technician at the 4S dealership, and he said it's common for new cars' braking systems to behave this way. The brake discs and pads aren't perfectly smooth yet and need to be broken in over a few dozen kilometers before the noise subsides. During the rainy season, moisture can cause the brake discs to rust, leading to friction noises, but there's no need to worry too much. Small sand particles or dust getting into the brake gaps can also cause sharp sounds when braking. Driving more will help them naturally settle in, and after washing the car, avoid braking hard immediately to prevent water residue. However, if the noise becomes louder or persists continuously, it might indicate that the brake pads are too thin or contain impurities, requiring immediate inspection and replacement to prevent further wear. Addressing such minor issues promptly ensures a more comfortable and worry-free driving experience.
I just started driving my brand-new Bora, and the brakes are making a loud noise. As a new driver, I'm a bit panicked. I called my mechanic friend, and he explained that brake noise in new cars is mostly normal during the break-in period, caused by friction from the uneven surface of the brake discs. Sometimes, after rain, the brake discs rust, and you hear a squeaking sound when you start driving, but it goes away once they heat up. Dust or small particles getting stuck can also cause noise. He suggested driving a few hundred kilometers to see if the noise lessens and regularly cleaning the brake system. If the noise persists, it might be due to overly hard brake pad material or misalignment, requiring a shop adjustment. Pay special attention to the brakes during new car maintenance, avoiding slamming them at traffic lights to reduce noise. Addressing issues early saves hassle.
