Cast iron, stainless steel. Aluminium metal matrix composites is also effective one..
disc brake components
The rotor is the disc in the disc brake system.

In case of cost..drum brake is better than disc brake.
A flywheel is made basically like a brake rotor, and the clutch disc is made like brake pads. The spinning flywheel is pressed against the clutch disc, which is made of hard steel--the idea being to get the clutch side of the trans to spin.
There are many purposes to using a disc brake. Disc brakes are mainly used in industrial drills because the disc brake stops the drill gently so it doesn't overheat.
pad brakes are disc brakes, it's known as changing brake pads for disc setup and changing brake shoes with drum brake setup.
The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper. The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper.
It looks like a hydraulic clamp. When hydraulic pressure is applied with the brake pedal, the caliper clamps the disc brake pads to the disc brake rotor to stop rotation.
With rear drum brake:-The brake drum may be out of round or may have a rust spot in it. -The brake drum may be cracked.With rear disc brake:-The brake disc may have extreme lateral runout or be mounted improperly. -The brake disc may be cracked. This would be dangerous-Combination of soft brake pads and a directional finish on the disc surface. A directional finish may go away with use and take the noise with it.Regardless of brake type:A brake disc or drum mounted to a bent hub flange or bent axle shaft can cause this noise.
Most modern cars have disc brakes on the front wheels, and some have disc brakes on all four wheels. This is the part of the brake system that does the actual work of stopping the car.The disc brake is a lot like the brakes on a bicycle. Bicycle brakes have a caliper, which squeezes the brake pads against the wheel. In a disc brake, the brake pads squeeze the rotor instead of the wheel, and the force is transmitted hydraulically instead of through a cable. Friction between the pads and the disc slows the disc down.Vented disc brakes have a set of vanes, between the two sides of the disc, that pumps air through the disc to provide cooling.
A disc brake kit is used to convert an older automobile's drum brakes to disc brakes. Your 2001 Gallant already has disc brakes. It would not require the disc conversion kit. When you begin to hear your brakes squeaking it is time to take your car to the repair shop for new brake pads.
