What is the function of the brake calipers in the braking system?

The function of the brake calipers in the braking system is to clamp the brake pads against the disc. When the brake pedal is engaged, hydraulic pressure is created, causing the calipers to move and press the brake pads against the rotor (or disc). This action generates the friction necessary to slow down or stop the vehicle. By effectively applying this pressure, the calipers play a crucial role in ensuring efficient and responsive braking performance.

Understanding this function is central to grasping how disc brake systems operate, as the interaction between the calipers, pads, and discs is vital for effective braking. Other components like the master cylinder and the actuation of brake lines are essential for generating the hydraulic pressure that enables the calipers to function, but the primary role of the calipers is specifically focused on the clamping action that regulates braking force.
