What happens when the brake pedal is pressed in a modern disc brake system?

In a modern disc brake system, the disc rotor is a main component that the brake pads squeeze against, creating friction to decelerate the wheel and vehicle rotation.
The caliper is activated by brake fluid hydraulic pressure produced from the vehicle's brake pedal and master cylinder, squeezing the brake pads against the disc rotor surface to create friction.
A caliper consists of multiple critical parts, including the caliper, mounting bracket, slide pins, locking bolts, dust boots, brake mounting clips, brake pads, and shims.
The brake piston is fed brake fluid through a banjo fitting, driving the piston forward towards the inside brake pad when the brake pedal is pushed.
Hydraulic brake pressure causes the caliper to move along the slide pins, pulling the outside brake pad against the opposite side of the disc rotor, generating friction and decelerating the vehicle.
When the brake pedal is pressed, the caliper receives high-pressure brake fluid from the master cylinder, pushing the piston into the inside brake pad and onto the disc rotor surface.
The braking process involves brake fluid pushing the piston, which in turn pushes the inner brake pad against the inside of the disc rotor, and then pushing the caliper along the slides, pulling the outer brake pad towards the opposite side of the disc rotor.

Learn about the components of a modern disc brake system, including the disc rotor, caliper, and brake pads, and how they work together to slow down a vehicle. Understand the hydraulic pressure system and how it generates friction to decelerate the wheel and vehicle rotation.
