How a Brake Caliper WorksReceives Pressure: When you push the brake pedal, brake fluid flows from the master cylinder into the caliper.Pushes Pistons: The fluid pressure forces internal pistons outward.Creates Friction: The pistons squeeze the brake pads tightly against both sides of the spinning brake rotor.Releases: When you take your foot off the brake pedal, the pressure drops and the pistons pull back, letting the wheel spin freely again
