What Is Caliper in Car?

In the world of automobiles, a caliper is a critical component that plays a vital role in the braking system of a car. Found in each wheel of a vehicle, the caliper is responsible for applying the necessary force to the brake pads, enabling them to clamp onto the brake disc or rotor. This action creates the friction necessary to slow down or bring the car to a complete stop.

Calipers come in different types, but the most commonly used in modern cars are disc brake calipers. These calipers consist of two main parts: the housing and the piston. The housing holds the brake pads, while the piston, when activated, pushes the brake pads against the rotor. This squeezing motion generates the friction needed to slow down or stop the car.

Calipers are typically made of cast iron or aluminum alloy, providing strength and durability. They are designed to withstand the high temperatures generated during braking, ensuring consistent performance and longevity.
