hydraulic brake
Definition
Noun: A hydraulic brake is a braking system that uses fluid pressure to transmit force from the brake pedal to the brake pads or shoes at the wheels. When the pedal is pressed, it moves a piston in a master cylinder, forcing brake fluid through lines to apply great force to the braking components.
Usage
The term "hydraulic brake" refers specifically to the complete fluid-based braking system. It is used to distinguish this technology from other types, such as mechanical or air brakes. * Most modern cars are equipped with a hydraulic brake system for reliable stopping power. * The mechanic diagnosed a leak in the hydraulic brake lines.
Advanced Usage
- Hydraulic brake fluid: The specialized fluid used in the system. It must maintain its properties under high pressure and temperature.
- It is important to change your car's hydraulic brake fluid periodically as recommended by the manufacturer.
Variants and Related Words
- Hydraulics (n): The science and technology concerned with the mechanical properties and use of liquids, especially under pressure.
- Disc brake (n): A type of hydraulic brake where a caliper squeezes brake pads against a disc (rotor).
- Drum brake (n): A type of hydraulic brake where shoes press outward against the inner surface of a drum.
Synonyms
- Fluid brake system
- Hydraulic braking system
Related Phrases
- Brake master cylinder: The component where the brake pedal's force is converted into hydraulic pressure.
- Brake caliper: The assembly in a disc brake system that houses the pistons and brake pads.
- Brake line/hose: The tubing that carries brake fluid from the master cylinder to the brakes at each wheel.
Noun
-
brake system in which a brake pedal moves a piston in the master cylinder; brake fluid then applies great force to the brake pads or shoes
