What is a brake caliper’s main function?

The primary function of a brake caliper is to press the brake pads against the rotor when hydraulic pressure is applied. When the driver presses the brake pedal, hydraulic fluid is sent from the master cylinder to the calipers. This hydraulic action causes the caliper to move and apply pressure to the brake pads, which then clamp down on the rotor. This friction between the brake pads and the rotor is what ultimately slows down or stops the vehicle. Understanding this function is crucial for brake system maintenance and repair, as any issues with the caliper's operation can lead to compromised braking performance.
