Must Brake Pads Be Replaced at a 4S Shop?

Brake pads do not necessarily need to be replaced at a 4S shop. The steps for replacing brake pads are as follows: 1. Open the engine compartment to check the brake fluid level to prevent overflow during the replacement process; 2. Remove the wheel where the brake is located; 3. Unscrew the bolts of the brake caliper and remove the brake pads; 4. Install the new brake pads, tighten the guide bolts, and complete the replacement. Types of brake pads include: semi-metallic brake pads, non-metallic brake pads, carbon fiber brake pads, and ceramic fiber brake pads. The working principle of brake pads is to convert the kinetic energy of the moving vehicle into heat energy through friction between the brake pads and the brake drum, as well as between the tires and the ground, thereby bringing the vehicle to a stop.
I've replaced brake pads both at 4S shops and independent garages. 4S shops are expensive but offer better assurance, especially for new cars still under warranty - I'd recommend going there. They use genuine OEM parts, their technicians know the specific vehicle models better, and they perform thorough brake maintenance after installation. But the prices are really steep - labor costs alone can be double outside shops. Established auto service chains are actually decent alternatives, just make sure they use reputable brake pad brands like Ferodo or Bosch. Last time I got mine changed at Tuhu Car Maintenance, they recorded the whole process and let me keep the old parts, saving me nearly 1,000 yuan. Remember to replace brake pads when thickness goes below 3mm - don't wait until they're completely worn and damage the rotors.
Just replaced the brake pads for the family's old car, something I've been considering for a long time. The dealership quoted over 2,000 RMB for the whole service, but a familiar repair shop only charged 800 RMB. The experienced mechanic emphasized three key points: whether the metal content in the brake pads is too high and could damage the rotors, if the noise-reducing shims are properly installed, and whether the guide pins are lubricated with the right grease. Actually, repair shops can also perform computer diagnostics on brake data—the key is to find a reputable shop with a vehicle lift. After the replacement, I deliberately tested the brakes with a few hard stops in an open area—no strange noises or pulling to one side. Those 200 RMB roadside stalls? Honestly, don’t even think about it—scary stuff.
