Is it necessary to replace brake pads at a 4S shop?

It is not necessary to replace brake pads at a 4S shop. Brake pads, also known as brake linings, are friction materials fixed on the brake drums or discs that rotate with the wheels. The friction linings and blocks bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. Their components include: 1. steel plate; 2. adhesive heat insulation layer; 3. friction block. The reasons for brake pad noise are: 1. metal hard spots can produce abnormal noise; 2. severe wear, the warning piece will make noise to prompt replacement; 3. the brake disc and pad are in the running-in period; 4. there are foreign objects between the brake pad and disc; 5. abnormal installation; 6. poor return of the brake caliper.
As a driver with over a decade of experience, I firmly believe that changing brake pads is no trivial matter. Brakes are directly related to the safety of you and your family. If the replacement isn't done properly, brake failure could be extremely dangerous. Although 4S shops may be more expensive, they use genuine parts, employ well-trained technicians, and have professional equipment that allows for comprehensive brake system inspections. My neighbor once had theirs replaced at a regular shop—they saved some money initially, but the brakes developed issues within six months, costing even more for rework. If it were up to me, I'd definitely choose a 4S shop, especially for new cars still under warranty, as it helps maintain service records and proves more hassle-free in the long run. Don't forget to regularly check your brake pad thickness—replace them once they wear down to 3mm without delay. Safety comes first, and this investment is absolutely worth it.
