What is the service life of brake pads?
2 Answers
Automotive brake pads can generally last for 10 kilometers, while high-quality brake pads can last up to 15 kilometers. Below is more information about automotive brake pads: 1. Automotive brake pads, also known as automotive brake linings, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction block bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration. Automotive brake pads are generally composed of steel plates, adhesive insulation layers, and friction blocks. The steel plates are coated to prevent rust, and the coating process is monitored using an SMT-4 furnace temperature tracker to ensure the temperature distribution during the coating process and guarantee quality. 2. A good and efficient braking system must provide stable, sufficient, and controllable braking force, along with excellent hydraulic transmission and heat dissipation capabilities. This ensures that the force applied by the driver on the brake pedal is fully and effectively transmitted to the master cylinder and sub-cylinders, while avoiding hydraulic failure and brake fade caused by excessive heat.
Just helped a friend with a similar issue a couple of days ago. Honestly, there's no standard answer for how many years brake pads last—it all depends on your driving habits. For someone like me who just commutes in the city, changing them every four years is normal, but buddies who love mountain roads might need replacements every two years. The most reliable method is to have the mechanic measure the thickness with calipers during each service. New pads are about 1.5 cm thick, and they must be replaced once worn down to 3 mm. Lately, I've noticed cars with electronic sensors make it super easy to tell—just wait for the dashboard warning light to come on. You can also do a simple check yourself: there's a U-shaped groove between the thin and thick sections of the pad, and once that groove disappears, it's time to open your wallet.
