Should Brake Pads Be Replaced If There Is a Burnt Smell?
1 Answers
Brake pads that emit a burnt smell due to excessive wear should be replaced. Below is an introduction to automotive brake pads: 1. Overview: Automotive brake pads, also known as brake linings, are friction materials fixed to 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. 2. Structure: The heat insulation layer is composed of non-heat-conducting materials, designed to insulate heat. The friction block consists of friction materials and adhesives. When braking, it is pressed against the brake disc or drum to generate friction, achieving the goal of vehicle deceleration and braking. Due to friction, the friction block gradually wears out. Generally, the lower the cost of the brake pads, the faster they wear. Once the friction material is used up, the brake pads should be replaced promptly. Otherwise, the metal plate will come into direct contact with the brake disc, ultimately leading to loss of braking effectiveness and damage to the brake disc.
