Brake pads are a crucial component in a car’s braking system, responsible for slowing down or stopping the vehicle. They are located inside the brake caliper, which presses against the brake rotor to create friction and slow the wheel’s rotation. In this article, we’ll discuss how Nissan Altima brake pads work and their role in a car’s performance.
Composition of brake pads:
Brake pads are made of a combination of metal shims, friction compounds, and fillers. The most common friction compounds used in brake pads are ceramic, semi-metallic, and organic.
Ceramic brake pads are made of ceramic fibers, copper fibers, and other fillers. They are known for their low dust and noise levels, as well as their longevity.
Semi-metallic brake pads are made of metal shavings, such as steel, iron, and other materials. They are known for their durability and high heat resistance, but they are noisier and produce more dust than ceramic brake pads.
Organic brake pads are made of organic materials, such as glass, rubber, and aramid fibers. They are known for low noise and dust levels but tend to wear out faster than ceramic or semi-metallic brake pads.
How brake pads work:
When the driver presses the brake pedal, brake fluid is sent from the master cylinder to the brake caliper. The brake caliper then uses pistons to press the brake pads against the brake rotor, creating friction. This friction slows down or stops the wheel’s rotation, which slows down or stops the vehicle.
The brake pads are designed to wear down gradually over time and need to be replaced when they reach a certain level of wear. If the brake pads are worn too thin, they will not be able to create enough friction to stop the vehicle effectively, which can lead to dangerous driving conditions.
Role in car’s performance:
Brake pads play a crucial role in a car’s performance by ensuring the vehicle’s and its passengers’ safety. A car’s braking system is one of its most important safety features, and worn brake pads can significantly decrease the brakes’ effectiveness.
In addition to safety, brake pads also play a role in a car’s fuel efficiency. When the brake pads wear down, they can create more resistance, leading to increased fuel consumption. This is why it is important to check and replace worn brake pads regularly.
