Where Are the Brake Pads Located in a Car?
1 Answers
Car brake pads are located in all four wheels of the vehicle. There are two types of brakes: disc brakes and drum brakes. The brake pads of disc brakes can be seen from the outside of the wheels, and they are more effective than drum brakes. The brake pads of drum brakes are inside the brake drum within the wheel and cannot be seen from the outside. Brake pads are an essential component of a car's braking system, consisting of a steel plate, friction material, and an insulation layer. They work by creating friction against the brake disc when braking, thereby achieving the purpose of stopping the vehicle. The working principle of car brake pads primarily relies on friction, converting the kinetic energy of the moving vehicle into heat energy through the friction between the brake pads and the brake disc, as well as between the tires and the ground, to bring the car to a halt. A well-functioning and efficient braking system must provide stable, sufficient, and controllable braking force, along with good hydraulic transmission and heat dissipation capabilities. This ensures that the force applied by the driver on the brake pedal is effectively transmitted to the master cylinder and individual wheel cylinders, while preventing hydraulic failure and brake fade caused by excessive heat.
