How often should rear drum brake pads be replaced?
4 Answers
Rear drum brake pads generally need to be replaced every 30,000 kilometers or so. However, the actual replacement interval depends on the vehicle's driving conditions and the driver's habits. It's also essential to check the thickness of the brake pads. If the brake pad thickness is less than 3MM, they should be replaced promptly. The braking system consists of a vacuum booster pump, master cylinder, wheel cylinder, brake pads, and brake discs. Brake system maintenance methods include: 1. High-temperature protection to prevent corrosion of the braking system, avoid brake pads seizing due to high temperatures, and eliminate brake squealing; 2. Clean brake discs, drums, and any components from oil stains, dirt, and friction dust to ensure proper heat dissipation; 3. Regularly replace brake fluid; 4. Periodically inspect the thickness of brake pads or brake shoes.
I've been driving for over twenty years, and there's really no fixed interval for replacing rear drum brake shoes—it largely depends on your driving habits and environment. If you frequently brake in city driving, you might need to check them every 20,000 to 30,000 kilometers, while those driving more on suburban roads or highways may only need inspection at 40,000 to 50,000 kilometers. I remember once ignoring the squeaking sound during braking, which resulted in longer stopping distances and nearly caused an accident. Since then, I've made it a routine to have the wear checked every six months or every 10,000 kilometers at the repair shop. Drum brakes are a bit more complex in structure than disc brakes, but you can perform simple checks yourself: pay attention to braking response and noises while driving, or remove the tire to inspect if the brake shoe thickness is running low. Safety comes first—don't cut corners by delaying replacements until it's too late. If you drive aggressively, be extra vigilant to help extend their lifespan.
As an office worker, I believe the replacement interval for rear drum brake pads depends on usage intensity. For those like me who commute daily in congested city traffic with frequent braking, they typically need replacement every 30,000-40,000 kilometers. Last time, the mechanic mentioned they should be replaced when thickness falls below 2mm - don't wait until you hear squeaking or experience brake dragging. Actually, self-inspection isn't difficult: regularly check brake pad condition during tire removal, or monitor for reduced braking performance. Delaying replacement not only poses risks but also accelerates wear on other components. I recommend checking them during every 5,000km or semi-annual maintenance - it's both safer and more convenient. Saving money isn't worth risking lives; timely maintenance is the reliable approach.
I enjoy tinkering with my car in my spare time. The replacement interval for rear drum brake shoes depends on actual wear and tear, with no fixed mileage. Driving conditions significantly influence wear: for example, frequent mountain driving with heavy loads accelerates wear, while city driving with light loads might allow replacement only after 60,000 kilometers. A simple self-check includes listening for unusual noises during braking and noticing changes in brake pedal feel. Delaying replacement can damage the brake drum or lead to brake failure, increasing accident risks. Remember to routinely check the wear thickness every 5,000 kilometers and replace them if they're too thin. Proper maintenance can also save some fuel.
