Why is there noise when braking the car?
2 Answers
The reasons for noise when braking a car are as follows: 1. Normal ABS activation: Cars equipped with ABS may produce abnormal noises during braking because the ABS system works by repeatedly locking and releasing the wheels. When the ABS is active, you may hear a clunking sound, which is normal and does not affect normal driving. 2. Rusty brake pads: Cars parked outdoors for a long time may experience rust on the brake pads. If the noise is caused by rust, it usually disappears after driving for a short while. If the noise persists, you can apply specialized lubricating oil at the connection between the brake pads and the brake caliper. 3. Newly replaced brake pads: When new brake pads are installed, they need to break in with the brake discs, which may cause noise. This is normal and nothing to worry about. 4. Excessive wear on brake discs or pads: Brake pads wear down over time, and when they reach a certain level of wear, they may produce noise. This situation requires attention, and replacement should be done based on actual driving conditions.
Recently, I also encountered a situation where my car's brakes were making noise, possibly due to worn brake pads or new parts still in the break-in period. It's quite common for brakes to squeak when the car is first started, especially after rainy days when the brake discs have some rust, which disappears after some friction. If the noise becomes louder or more screeching, it might be due to small stones or foreign objects stuck in the brake system, and they should be removed as soon as possible to prevent damage to the brake discs. I make it a habit to regularly check the thickness of the brake pads and have them measured at a repair shop at least every six months, as deteriorating braking performance can be very dangerous. Don't ignore these small issues—they are related to driving safety, and simple maintenance can save you from costly repairs.
