What are the reasons for a sedan making noise when braking?
2 Answers
The reasons for a sedan making noise when braking are: 1. Rust on the brake disc or brake pads; 2. The sedan has just had new brake pads installed; 3. Excessive wear on the brake disc and brake pads; 4. Assembly issues, such as incorrect brake pad model. The solutions for a sedan making noise when braking include: 1. Applying butter or specialized lubricant to the connection between the brake pads and brake caliper; 2. Regularly inspecting and replacing the brake disc and brake pads; 3. Reinstalling the brake pads. Braking, also known as deceleration, refers to the action of stopping or reducing the speed of a moving motor vehicle or other transportation machinery, which is divided into drum brakes and disc brakes.
My car makes noise when I brake, and I've encountered this issue several times. The most common reason is excessive wear on the brake pads, where the friction material is nearly gone, causing the metal part to directly rub against the brake disc, producing that sharp, screeching sound. Another possibility is foreign objects on the brake disc, such as small stones or rust, especially during rainy days or early mornings when humidity causes rust to form on the disc surface, leading to squeaking noises when braking. I recommend regularly checking the brake pad thickness—at least every 5,000 kilometers—and replacing them if they're too thin. Don't ignore this, as it could lead to longer braking distances and increased accident risks. Another potential cause is that the brake pads are made of overly hard material or were installed at an incorrect angle, causing vibration noises; opting for softer, low-noise pads can help. In daily driving, try to avoid sudden braking to reduce overheating and wear. Proper maintenance can save you a lot of trouble.
