Is it necessary to replace car brake pads at a 4S shop?
2 Answers
Replacing car brake pads does not require going to a 4S shop. Here is the method for replacing brake pads: 1. Open the engine compartment to check the brake fluid level to prevent overflow during replacement; 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 the replacement is complete. Additional information: 1. The working principle of brake pads is: by utilizing the friction between the brake pads and the brake drum, as well as between the tires and the ground, the kinetic energy of the moving vehicle is converted into heat energy through friction, thereby stopping the vehicle. 2. Types of brake pads include: semi-metallic brake pads, non-metallic brake pads, carbon fiber brake pads, and ceramic fiber brake pads.
As a veteran driver with ten years of experience, I find that getting brake pads replaced at a 4S shop is the most hassle-free option. Genuine OEM parts guarantee a perfect fit, and their technicians are intimately familiar with their own models. Plus, they often include a complimentary brake system inspection after the replacement. Although it costs about 30% more, my last experience at a small garage resulted in severe squealing noises, forcing me to go back for rework—factoring in lost wages, I actually ended up losing money. I recommend new drivers opt for 4S shops during the first maintenance, while out-of-warranty older cars can afford some comparison shopping. The key is to supervise the unsealing of new packaging and personally verify the anti-counterfeit code on the brake pads—after all, safety components are not something to take lightly.
