Word: Disc Brake
Definition: A disc brake is a type of brake used in vehicles where friction is created by pressing brake pads against a round metal disk (called a rotor) that spins with the wheel. This action slows down or stops the vehicle.
Usage Instructions: - Disc brakes are commonly found in cars, motorcycles, and bicycles. - They are usually more effective than old-fashioned drum brakes, especially in wet conditions.
Example Sentence: "When I pressed the brake pedal, the disc brakes quickly slowed the car down."
Advanced Usage: - In high-performance vehicles, disc brakes are often made from materials like carbon-carbon or ceramic to withstand high temperatures and improve braking efficiency. - Some modern vehicles use electronic systems to enhance the performance of disc brakes, allowing for features like anti-lock braking systems (ABS).
Word Variants: - Disc Brake System: Refers to the complete setup including the brake pads, rotor, and hydraulic components. - Disc Braking: The process of using disc brakes to slow down or stop a vehicle.
Different Meanings: - The term "disc" can also refer to a flat, circular object in other contexts, like a CD (compact disc) used for music or data storage.
Synonyms: - Rotor Brake: Another term sometimes used to refer to disc brakes, emphasizing the rotating part. - Friction Brake: A broader term that includes any braking system that uses friction to slow down.
Idioms and Phrasal Verbs: - There are no specific idioms or phrasal verbs directly related to "disc brake," but you might hear phrases like "hit the brakes," which means to stop quickly or slow down.
Summary: A disc brake is an important safety feature in many vehicles, using friction to help slow down or stop.
