How Often Should the Brake Pads of a Rear Eight-Wheeler Be Replaced?
3 Answers
Rear eight-wheeler brake pads are generally replaced every 30,000 kilometers or so. The relevant introduction to replacing brake pads is as follows: Method for replacing brake pads: Remove the tire to expose the brake caliper and brake disc. Apply lubricant to the gaps of screws or nuts that need to be loosened and removed. Hang the brake caliper with a rope, then remove the old brake pads. Lift the engine hood and unscrew the cover of the brake fluid box. Align and embed the new brake pads, placing the inner piece with the wear warning indicator on the inside. Precautions for replacing brake pads: Check whether the replacement brake pads are genuine parts (i.e., matching products), the integrity of the product packaging, whether the anti-counterfeiting marks and packaging labels are consistent with those on the brake pads, and whether the product model matches the content of the certificate.
It really depends on how hard you drive your vehicle. From my years of experience driving trucks, rear eight-wheel brake pads are generally recommended for inspection every 40,000 to 50,000 kilometers. Especially when carrying heavy loads or frequently driving on mountainous roads, they wear out much faster. I've encountered situations where brake pads were completely worn out after just 30,000 kilometers when hauling heavy cargo—scary stuff. Don't just rely on fixed intervals; regularly check the brake pad thickness visually. If they're worn down to less than 3 millimeters, replace them immediately. Or if you hear metal grinding noises when braking, don't delay. In daily driving, leave more distance and avoid sudden braking—this can extend their lifespan by a year or two. With good vehicle maintenance, they can last 60,000 to 70,000 kilometers, but don't take risks for safety's sake. Safety always comes first.
When it comes to professionally handling these matters, my view is that there are no rigid standards—it depends on the usage environment and driving habits. For example, frequent braking in heavy urban traffic may require replacement at 40,000 kilometers, while highway driving with light loads can easily extend to 60,000 kilometers. I recommend that car owners perform simple checks every quarter: feel the brake discs by hand for deep grooves, or inspect the brakes when checking for tire pressure imbalances. Replacing brake pads promptly avoids subsequent damage to the calipers and saves money; delaying too long not only increases repair costs but also affects handling. Based on my observations, stable driving combined with regular maintenance makes replacement intervals easier to predict.
