What is the method to determine if brake pads need replacement?
2 Answers
The method to determine if brake pads need replacement is when the braking sensation feels lighter than usual or if braking seems more strenuous, then it's time to replace them. Brake pads, also known as brake linings, are critical safety components in a car's braking system, playing a decisive role in the effectiveness of all braking. Brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, with the coating process monitored by an SMT4 furnace temperature tracker to ensure quality by detecting the temperature distribution during coating. The heat insulation layer is made of non-heat-conducting materials, designed to insulate heat.
I often tinker with my car, and checking brake pads is particularly simple and practical. Just crouch next to the wheel and peek through the wheel hub hole to check the pad thickness. For most car models, replace them when they wear down to 3mm, otherwise braking performance will suffer. If you hear a squealing sound when braking, it's a sure warning that the pads are nearly gone. Or if the brake pedal feels spongy and less responsive than before, it's time for a quick replacement. I also have a backup method: regularly inspect the brake discs. If there are deep grooves on the disc surface, it's likely caused by worn-out pads. Make it a habit to check monthly and more frequently before highway drives—safety first. Delaying replacement significantly increases the risk of brake failure, especially on slippery roads, and can lead to costlier repairs. Developing this habit saves hassle, and all you need is a tape measure.
