Each caliper of the wheel has two brake pads, with the friction surface of these pads confronting the rotor. So, when brakes are hydraulically applied (In simple words, brakes are made operational with liquid oil) then, the caliper squeezes the brake pads together onto the spinning rotor to stop the vehicle.
