Can brake pads still be used when they are down to 3mm?

They can still be used, as the wear limit is 2.5mm, but for safety reasons, it is recommended to replace them in advance. Below is relevant information about brake pads: 1. Brake pad maintenance: The effectiveness of a car's braking system largely depends on the brake pads, making them crucial for vehicle safety. Regular inspection and protection are essential. Under normal driving conditions, inspect the brake shoes every 5,000 kilometers. Not only should the remaining thickness be checked, but also the wear condition of the shoes, whether both sides are wearing evenly, and if they return to position smoothly. Any abnormalities should be addressed immediately. 2. Brake pad replacement: When replacing, it is best to use the original manufacturer's brake pads to ensure optimal braking performance and minimal wear between the brake pads and discs. After replacement, be sure to pump the brakes several times to eliminate the gap between the shoes and the brake discs.
Last time when changing brake pads, the mechanic explained it clearly to me - 3mm thickness really means it's time for replacement. When my old Sagitar reached this wear level, the brakes started squeaking and the steering wheel would shake. The repair shop measured with calipers and found the metal backing plate was nearly exposed. Continuing to use them not only increases braking distance, but worse, risks scoring the brake rotors - replacing rotors costs several times more than pads. One rainy day when picking up my kid, I almost couldn't stop at an intersection, which scared me into visiting the repair shop the next day. I suggest you immediately check your brake fluid condition too, as overly thin pads affect hydraulic pressure.
