How to Determine Whether Brake Pads Need Replacement
3 Answers
Methods to determine whether brake pads need replacement include: 1. When you feel that the braking sensation becomes lighter or the braking effort increases, it is likely that the brake pads are severely worn and need immediate replacement; 2. You can directly inspect the wear level of the brake pads. Generally, it is recommended to check them every 3,000 kilometers. If the brake pads are worn down to one-third of their original thickness, they should be replaced. If severely worn brake pads are not replaced in time, various degrees of impact may occur. Firstly, when braking, the car may produce a metallic grinding sound, which will become more noticeable over time.
I've been driving for ten years and often encounter issues with brake pads. The most straightforward way to determine if they need replacement is by listening for sounds. If you hear a squeaking noise or a sharp metallic scraping sound when braking, it's likely the wear indicator telling you it's time for a change. I personally pay attention to these noises at traffic lights or when going downhill. Additionally, you can simply perform a visual inspection. Find a moment to park your car on level ground and easily peek through the wheel gap to check the thickness of the brake pads. If it's less than 3 millimeters, don't delay—get them replaced immediately. If the brake feels soft, the braking power isn't as strong as before, or the stopping distance increases, those are also warning signs. I recommend getting them professionally checked every 10,000 kilometers or so to avoid sudden emergencies while driving. Remember, brake issues directly affect safety—don't wait to save money; replace them when needed.
As a family car, I pay special attention to safety, especially since children are often in the car. Determining whether brake pads need replacement comes down to monitoring simple indicators in daily use. First, observe braking performance—if the pedal sinks deeper after hard braking or the steering wheel vibrates during braking, these subtle changes may indicate worn brake pads. Another effective method is regular thickness checks. You can do this yourself in good lighting by removing the wheel cover or using a mirror to inspect; if the thickness falls below 2-3mm, it's time for action. I make it a habit to measure every six months to avoid on-road risks. If the car produces persistent scraping noises during braking, treat it as a warning not to ignore. Additionally, modern dashboards may illuminate a yellow warning light, directly signaling an issue. Safety comes first—don’t delay upon noticing these signs. Visit a repair shop for replacements; the cost is modest but ensures family safety.
