Methods to determine whether brake pads need replacement are as follows 1. Check the thickness: A new brake pad is generally about 1.5cm thick, and the thickness of the brake pad should not be lower than the wear indicator. 2. Listen for sounds: If there is abnormal noise when lightly applying the brakes (it could also be the effect of the brake pads wearing in during initial installation), the brake pads must be replaced immediately. 3. Feel the pedal: If you feel that it is very difficult to press the brake, often needing to press it deeper than usual to achieve the same braking effect, and when emergency braking, you noticeably feel the pedal position is lower, it is possible that the brake pads have basically lost their friction. At this time, the brake pads should be replaced.

As a veteran driver with over 20 years of experience, I've summarized several methods to determine when brake pads need replacement. The key is listening for sounds: when braking, if you hear a sharp, screeching noise like metal scraping, it likely means the brake pads are worn out and the warning metal tabs are signaling. Next, pay attention to changes in the brake pedal feel; if it feels spongy or vibrates excessively, like slipping on wet roads, it indicates insufficient braking power. Regular thickness checks are crucial—use a flashlight to inspect the inner side of the wheel hub, and replace the pads if they're thinner than 5mm. Ignoring this can lead to longer braking distances and increase the risk of rear-end collisions in rain or snow. Checking every six months is inexpensive but life-saving—I advise not waiting until extreme situations arise.

I enjoy tinkering with my car in my spare time, and there are several simple methods to determine when to replace brake pads. Listen for sounds: Pay attention to any metallic squeaking or grinding noises every time you brake to slow down—that's the wear indicator signaling. Check the pedal: If it feels too hard or soft and unstable, it's time to inspect the thickness. Visual inspection is the most straightforward—remove the tire and use a ruler to measure the brake pad thickness. If it's below 3mm, replace them immediately. Failing to do so can damage the brake discs, leading to more costly and time-consuming repairs. Regular maintenance also saves fuel since dragging brakes increase resistance. Make it a habit to check twice a year for safety and cost-effectiveness.

Brake pad wear directly affects driving safety, so it's crucial to recognize the warning signs. For instance, if you hear screeching noises or notice a significant increase in braking distance, it's time to suspect an issue. Modern vehicles come with built-in sensors—don't hesitate when the dashboard warning light illuminates. Simple DIY checks: gently brake on a flat surface to feel for abnormal vibrations, or use a mirror to inspect pad thickness. Delaying replacement heightens rear-end collision risks, especially at night or in rainy conditions. New pads are affordably priced—prioritize protecting yourself and your family.
