How often should brake pads for sedans be replaced?
2 Answers
Generally, the normal wear lifespan of brake pads is around 60,000 kilometers. Below is some information about brake systems: 1. Brake Pads: Also known as brake linings, they are the most critical safety components in a vehicle's braking system. The effectiveness of all braking performance is decisively influenced by the brake pads; Brake pads are typically composed of a steel plate, an adhesive heat insulation layer, and friction material. The heat insulation layer is made of non-heat-conductive materials to provide thermal insulation; 2. Friction Material: Composed of friction materials and adhesives, it creates friction when pressed against the brake disc or drum during braking, thereby achieving the purpose of decelerating and stopping the vehicle.
Having driven a sedan for over a decade, I've learned that brake pad replacement isn't a one-size-fits-all matter. When I first got my car, I thought mileage alone would dictate when to change them. But during a period of constant city traffic where I was frequently braking, the pads wore out at just over 20,000 km – nearly causing a rear-end collision. Generally speaking, inspecting and replacing them every 30,000-50,000 km under normal driving conditions is safest. However, if you're a new driver or often drive in congested areas where wear accelerates, consider replacing them around 30,000 km. The key is regular monitoring: listen for high-pitched squealing while driving (a warning signal), and have a mechanic measure thickness biannually – don't delay if it's below 3mm. Neglecting this isn't just dangerous; it can damage the brake rotors too, costing you unnecessary repairs. My advice? Develop the habit of adjusting replacement intervals based on your driving patterns rather than blindly following manufacturer standards.
