About the brake discs

(Disc Brake Systems: The Basics).  (shared by RDBRAKE) Disc brakes are a type of brake that uses a disc-shaped rotor and a caliper with pads to slow or stop a vehicle. They are found on almost all modern cars and trucks, and for good reason. Disc brakes offer several advantages over drum brakes, the other common type of brake system. (How Disc Brakes Work) When you step on the brake pedal, hydraulic fluid is forced through the brake lines to the brake calipers. The calipers contain pistons that push against the brake pads, which are pressed against the rotor. The friction between the pads and the rotor slows the vehicle down. (Advantages of Disc Brakes) Better heat dissipation: Disc brakes are much better at dissipating heat than drum brakes. This is important because heat is a major enemy of brakes. When brakes overheat, they can fade, which means they lose their stopping power. Consistent braking performance: Disc brakes provide consistent braking performance, even in wet or dusty conditions. This is because the pads and rotors are always exposed to air, which helps to keep them cool and dry. Less brake fade: Disc brakes are less prone to brake fade than drum brakes. This is because the pads and rotors are always exposed to air, which helps to keep them cool. Easier to maintain: Disc brakes are easier to maintain than drum brakes. The pads and rotors can be replaced without having to take the wheel off. Types of Disc Brakes There are two main types of disc brakes: solid disc brakes and ventilated disc brakes. Solid disc brakes are the simplest type of disc brake. They consist of a solid disc of metal that is attached to the wheel hub. Ventilated disc brakes have a series of vanes or fins cast into the disc. These vanes help to dissipate heat more effectively. Maintenance Tips Inspect your brakes regularly. Look for signs of wear, such as worn brake pads or rotors. Replace your brake pads and rotors as needed. Don't wait until they are completely worn out. Have your brakes bled regularly. This will help to ensure that your brakes are working properly.
