Drum brakes vs disc brakes

Let’s talk about drum brakes first. The drum brakes contain a set of shoes inside. If you press the brake, the shoes pressurize the wheels to stop. Due to the friction between the shoes and the wheel, the car stops.
But, it has a problem when you are on slop with a heavy load. If you press the brake, again and again, the brake shoes fade. This brake fade causes the brakes to work improperly.
Though disc brakes follow the same idea, the design of disc brakes is far better. Inside the disc brakes, there are a caliper, brake pads. When you press the brakes, the rotors clamp together to stop the vehicle.
The disc brakes can come in contact with air. So it doesn’t overheat easily. Which prevents the disc brakes from any damages.
