Hebei Chengen Huanbao Technology Co., Ltd., a professional auto parts manufacturer since 2015, provides clear guidance on when to replace brake pads to ensure vehicle safety and optimal braking performance. Knowing when to replace brake pads involves monitoring several indicators, such as a squealing or grinding noise during braking, which signals that the brake pad material is worn down to the wear indicators. Another sign of when to replace brake pads is reduced braking responsiveness or longer stopping distances, as worn brake pads cannot generate sufficient friction. Most manufacturers recommend replacing brake pads when their thickness is less than 3mm, and our customer service team can advise on specific measurements based on vehicle models. For vehicles operating in harsh conditions, such as those in Germany, Italy, or South American countries with mountainous terrain, more frequent checks are advised to determine when to replace brake pads. Our high-quality brake pads, exported globally, ensure that timely replacement with our products maintains peak braking performance and safety.
