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

Brake pads do not necessarily need to be replaced at a 4S shop; they can also be replaced at a repair shop or even by yourself. The cost of brake pads varies depending on the location, vehicle model, and the material of the brake pads. Outside of 4S shops, the quality of brake pads may differ, and it cannot be guaranteed whether they are original. Below is some relevant information: 1. Whether the brake discs need to be replaced can be determined by yourself. Each person's driving habits have a certain impact on the replacement of brake pads. If they are replaced based solely on a uniform mileage standard, it may lead to waste or excessive wear, posing potential hazards. Generally, new brake pads are about 1.5 cm thick. If they wear down to one-third of their original thickness, meaning less than 5 mm, it is recommended to replace them promptly. 2. A good and efficient braking system must provide stable, sufficient, and controllable braking force. The working principle of braking mainly relies on friction, involving the friction between the brake pads and the brake discs (or drums) as well as the friction between the tires and the ground. When replacing brake pads, it is advisable to use original spare parts provided by the manufacturer. Only in this way can the braking effect between the brake pads and the brake discs be optimal, with minimal wear. You should choose brake pads produced by reputable manufacturers, which have a license number, specified friction coefficient, and comply with execution standards. The packaging should include a certificate of conformity, production batch number, and production date.
I think it's really necessary to replace brake pads at a 4S dealership, especially if your car is still under warranty or you're particularly concerned about safety. 4S shops use genuine parts for better compatibility, avoiding brake judder or noise – this is crucial since brakes are life-critical. I once opted for cheaper pads at a small garage, only to experience longer braking distances that nearly caused an accident, requiring a redo. 4S shops provide comprehensive service: technicians use professional equipment to inspect brake fluid and calipers, ensuring everything functions properly. Though pricier, it's worth it. If budget is tight, reputable chain repair shops are an alternative, but verify parts brands and keep invoices for dispute resolution. Developing a habit of checking pad wear during routine maintenance is wise – don't wait until they're completely worn out.
I don't think it's necessary to insist on changing brake pads at 4S dealerships. The money saved can be used for other purposes. Finding a professional auto repair shop outside and using quality aftermarket parts may cost less than half of what 4S dealerships charge. I often do this myself - asking the mechanic to first check the pad thickness and material, choosing ceramic or semi-metallic options as long as they're not no-name products. The installation process is actually quite simple, with the key points being the mechanic's experience and tool precision. Of course, 4S dealerships offer standardized services where they'll clean the calipers and inspect other components during pad replacement, but the extra time and money spent might be better used for other maintenance. If your car is relatively new or prone to issues, you could try a hybrid approach: visit the 4S dealership for the first replacement to understand the situation, then maintain at smaller shops afterward. Remember safety first - always replace worn components promptly.
