Under normal circumstances, brake discs need to be replaced every 50,000 to 80,000 kilometers. Brake pads should be replaced every 20,000 to 30,000 kilometers. Below are the relevant details: Reasons for replacing brake discs: The replacement cycle for brake discs is related to individual driving habits and road conditions. Brake discs are a wear-prone component in the braking system. As the vehicle's mileage increases, the brake discs will continuously wear down. Reasons for replacing brake pads: When the vehicle has traveled approximately 30,000 to 60,000 kilometers, the brake pads usually experience significant wear. Before the brake pads are completely worn out, the warning tab on the brake pads will rub against the brake disc when braking, producing a sharp, piercing sound.

As a seasoned expert in the automotive field, I understand that brake discs and pads don't have a fixed replacement schedule - it entirely depends on wear condition and your driving habits. Typically, brake pads require replacement every 40,000 to 80,000 kilometers, especially if you frequently drive in congested urban areas where constant braking accelerates wear. Brake discs are more durable and should be inspected after about two sets of pad replacements, generally needing consideration for replacement around 80,000 to 120,000 kilometers. The key is to have technicians measure the thickness during regular maintenance; excessively worn components not only reduce braking efficiency but may also cause scoring or warping. I've seen many car owners ignore warning signs like unusual noises or increased stopping distances - these are serious red flags. Additionally, proper brake system compatibility is crucial, as different vehicle models have distinct disc/pad designs. For instance, inappropriate friction materials can cause noise or vibration, compromising driving safety. Adopting smooth driving techniques and avoiding sudden stops can significantly extend service life.

As a seasoned driver with over a decade of experience, primarily commuting, I've learned that brake pads typically need inspection and replacement every 50,000 to 60,000 kilometers, while brake discs last longer, usually around 100,000 kilometers. The key is safety first. If you notice squeaking sounds when braking or a spongy pedal feel, don't delay—get it fixed immediately. I once experienced significantly longer braking distances in rainy weather, nearly causing a rear-end collision; replacing them brought much peace of mind. Frequent stops and starts in urban traffic accelerate wear, so don't wait for the dashboard warning light. It's best to have the wear checked during annual maintenance—don't skimp on that inspection fee. Wear is even more pronounced on hilly roads or with heavy loads, so early prevention is always wise. The braking system is a matter of life and death—never take it lightly.

I just got my driver's license and don't know much about replacing brake pads and rotors. After checking various sources, I found there's no specific time frame—it mainly depends on actual wear. Typically, brake pads may need replacement every 40,000 to 50,000 kilometers, while rotors can last over 70,000 to 80,000 kilometers. As a new driver who's still not very skilled, if the car shakes or makes screeching noises when braking, it's time for a quick check. The most reliable method is having a mechanic measure the thickness with calipers—if it meets the standard, they're still usable. Remember to regularly maintain your car and confirm the wear level is safe. Driving smoothly and avoiding frequent hard braking can extend the replacement interval.
