How Long Do Brake Pads Last?
3 Answers
Brake pad lifespan varies depending on specific conditions: 1. Front brake pads typically last approximately 30,000 to 50,000 kilometers; 2. Rear brake pads usually last about 60,000 to 100,000 kilometers. Brake pads refer to the friction materials fixed on the rotating brake drum or brake disc of the wheels, where the friction linings and blocks withstand external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. The method for replacing brake pads is: 1. Lift the vehicle and remove the tire; 2. Unscrew the fixing screws on the brake caliper and remove the brake caliper; 3. Remove the old brake pads and push back the brake caliper piston; 4. Clean the mounting bracket of the brake disc and install the new brake pads.
I remember my first car's brake pads started squeaking at around 40,000 kilometers. This really depends on driving habits and road conditions. If you're driving mountain roads daily or have a habit of sudden braking, the brake pads wear out much faster. Most new car models now come with wear sensors – the dashboard light will tell you when it's time for replacement. Once when helping a friend check his car, I noticed the left front pad was significantly thinner than the right rear one, which turned out to be uneven wear caused by a sticking caliper. Reminder to everyone: during maintenance, don't just check thickness standards – also inspect the caliper condition. Oh, and if you hear unusual noises when braking on rainy days, get it checked immediately – the metal backing plate scraping against the rotor will cost you way more to fix.
Last week during maintenance, I specifically had the brake pads measured and immediately replaced them as they were down to just 3mm. The mechanic said the average lifespan for commuters is 30,000-50,000 km, but this figure is quite inflated. Those who frequently drive on highways can get up to 70,000 km, while food delivery e-bikes with modified brake pads may need replacement twice a year. The key is not to wait until they're completely worn out, as that can damage the brake discs. Nowadays, dealerships use endoscopes to check thickness conveniently, so I have them inspected every 10,000 km. A sudden drop in brake fluid level is also a warning sign, possibly indicating a leaking wheel cylinder that's carrying away brake pad material.
