About Brake Caliper: The brake caliper fits like a clamp on a wheel’s rotor to stop the wheel from turning when you step on the brakes. Inside each caliper is a pair of metal plates known as brake pads. When you push the brake pedal, brake fluid creates pressure on pistons in the brake caliper, forcing the pads against the brake rotor and slowing your car.
