Brake disc, also known as brake rotor, belongs to the braking system of a vehicle. It is usually made of metals and it often works along with other parts to achieve its own mission. The main job of the brake disc is to slow or stop the vehicle. When the brake pedal is depressed, the brake caliper would squeeze the brake pads against the brake disc to create friction that retards the rotation of a shaft or to reduce its rotational speed or hold it stationary. In a word, brake disc is an essential part of braking system. However, because brake disc works in continuous frictions and is exposure to high temperature environment frequently, it will wear out or be warped over time and will eventually need to be replaced. As for when to replace, you need to be aware of some common and recognizable symptoms of a broken brake disc. First, brake disc produces squealing or squeaking sounds which can be heard when depressing the brake pedals. Second, excessive vibration comes from the brakes, which can be felt in the brake pedals when putting feet on it. Third, visual scoring or grooves on the face of the brake disc. For your reminders, the brake disc needs to be changed in pairs in front or rear. For more precise inspection, you need to measure the thickness of the brake disc every year to make sure your brake system works well. Genuine Hyundai brake disc should be a wise choice for you.
