Brake lining

Brake lining is a type of friction material that is used in the brake system of vehicles. It is a crucial component that ensures the proper functioning of the braking system and contributes to the overall safety of the vehicle.

History

The concept of brake lining was first introduced in the early 20th century. The initial materials used for brake linings were primarily asbestos due to its heat resistance properties. However, due to health concerns related to asbestos exposure, alternative materials have been developed and used since the late 20th century.

Function

The primary function of the brake lining is to convert the kinetic energy of the moving vehicle into thermal energy by friction. When the brake pedal is pressed, the brake lining is forced against the brake drum or brake disc, creating friction and slowing down or stopping the vehicle.

Materials

Brake linings are made from a variety of materials, each with its own properties and advantages. The most common materials used today are semi-metallic and non-asbestos organic (NAO) materials. Semi-metallic brake linings are durable and provide excellent heat dissipation, while NAO brake linings are softer and quieter.

Maintenance and Replacement

Brake linings wear down over time and need to be replaced to ensure the effectiveness of the braking system. The frequency of replacement depends on various factors such as driving habits, vehicle type, and the quality of the brake lining material. Regular inspection and maintenance of brake linings are essential for vehicle safety.
