At what point should car brake pads be replaced?
2 Answers
Brake pads need to be replaced under the following circumstances: 1. When the vehicle has traveled approximately 80,000 kilometers, the car brake pads will become relatively thin due to wear and tear, at which point new brake pads should be replaced to ensure driving safety. 2. Observe the thickness of the brake pads. Generally, new brake pads are about 2.5 centimeters thick. When the thickness of the brake pads decreases to approximately 0.5 centimeters, they need to be replaced. 3. Listen for sounds. Since the brake pads will rub against the braking system when braking, you can determine whether the braking system is functioning properly by listening to the sound when applying the brakes. If there are unusual noises, the brake pads should be inspected and replaced. 4. Determine whether the brakes are functioning properly by the feel of the brake pedal. If you notice that the brakes feel soft and lack stopping power, the brake pads need to be replaced.
I've been driving for decades, and when brake pads need replacement, they're usually worn very thin. Specifically, once the thickness drops to around 2 millimeters, they must be replaced, otherwise they can easily scratch the brake discs. I have a technician inspect them every 20,000 kilometers. If there's a sharp screeching sound when braking, that's the metal indicator giving a warning. Remember, safety comes first—low braking efficiency increases the risk of accidents, especially on slippery roads. Regular maintenance is better than breaking down halfway and can also save you from costly repairs later on.
