How Brake Pads Work
Brake Pad Mechanism
The mechanism of brake pads is integral to the braking system, ensuring your vehicle can stop safely and efficiently. When you depress the brake pedal, a series of events are set in motion starting with the brake master cylinder. This component sends hydraulic fluid through the brake lines, creating pressure that activates the brake callipers. The callipers house the brake pads and, when pressurised, force these pads against the spinning brake discs attached to the wheels.
This contact generates friction on outer pad, which slows down the wheel's rotation and ultimately brings the vehicle to a stop. The friction also converts kinetic energy into heat, which dissipates into the air. This process must be efficient and reliable, as any failure in the mechanism can compromise your safety. Regular maintenance and checks ensure that the brake pads, along with the entire braking system, function correctly and keep you safe on the road.
Role in Vehicle Safety
Brake pads play a pivotal role in vehicle safety by under braking load and enabling effective and controlled stopping.
