When Should Brake Pads Be Replaced?
2 Answers
Brake pads should generally be replaced after the vehicle has traveled 80,000 kilometers or approximately 4 years, although the replacement time may vary depending on the vehicle's usage. Situations that require brake pad replacement include: 1. When the thickness of the brake pads is reduced to below 0.5 centimeters; 2. When the vehicle produces squealing or hissing noises during braking; 3. If you notice reduced braking efficiency, the brake pedal feels heavy, or the braking distance becomes excessively long, it's time to replace the brake pads. Brake pads are a crucial component of the automotive braking system, typically composed of a steel plate, friction material, and an insulation layer. They function by creating friction against the brake disc when the brakes are applied, thereby achieving the braking effect. As a key safety component, the quality of all braking performance is decisively influenced by the condition of the brake pads.
As a car owner, I usually pay close attention to the feel of the brakes while driving. When the brakes start making a sharp hissing sound, like metal rubbing against metal, it's a signal that the brake pads are nearly worn out. Last time, I noticed it after the brakes became softer—stepping on them didn't slow the car down as quickly as before, and it took a much longer distance to stop. In such cases, it's crucial to address the issue immediately, otherwise, completely worn-out brake pads can damage the brake discs, doubling the repair costs. Generally, it's advisable to check the brake pad thickness every 10,000 to 15,000 kilometers and replace them if they're too thin. Developing a habit of checking the brake fluid level is also beneficial, as maintaining the overall system ensures driving safety. Don't wait until the brakes fail completely to panic—that could lead to rear-end collisions, endangering yourself and others.
