Do brake pads have to be replaced at a 4S shop?

Brake pads do not necessarily have to be replaced at a 4S shop; they can also be replaced at a repair shop. Brake pads, also known as brake linings, are critical safety components in a car's braking system. The effectiveness of all braking depends decisively on the brake pads. 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, and the coating process uses an SMT4 furnace temperature tracker to monitor the temperature distribution during coating to ensure quality. The working principle of braking is primarily based on friction. By utilizing the friction between the brake pads and brake discs, as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy through friction, bringing the car to a stop.
It's not necessary to go to a 4S shop for brake pad replacement. I've been getting mine changed at chain quick-service shops for a long time. They use major brands like Bosch or Ferodo for brake pads, so the quality is guaranteed. The price is over 30% cheaper than at 4S shops, and the service is just as good. Of course, you should choose qualified shops like Tuhu or Tmall Auto Care, where the technicians are certified and the equipment is professional. The key is to confirm in advance whether they can provide official invoices and warranty certificates, so you're protected in case of issues. You can also check labor costs and parts prices on their official websites beforehand to have a clear idea.
My experience is that changing brake pads mainly depends on the vehicle's age. For new cars still under warranty, it's advisable to go to a 4S shop to avoid affecting the warranty of other components. However, for older cars, there's really no need to spend extra money unnecessarily; just find a reputable independent repair shop. They often have more experience handling various car models. Last week, I had mine changed at a shop recommended by a friend for just over 300 yuan, while the 4S shop quoted over 500 yuan. But it's important to ensure the mechanic follows standard procedures, especially since new brake pads need a break-in period. After installation, drive at low speed and pump the brakes a few times to eliminate any gaps.
