hydraulic brake: meaning, definition, pronunciation and examples

No. 'Hydraulic' describes how the braking force is transmitted (using fluid). 'Disc brake' describes the type of friction mechanism (a pad squeezing a disc). Most modern disc brakes are hydraulically actuated, so the terms are often used together, but they refer to different aspects.

Air is compressible, unlike brake fluid. This causes a 'spongy' feel at the brake pedal because some of the pedal travel is compressing the air bubbles instead of directly moving the fluid to apply the brakes, significantly reducing braking efficiency and safety.

Absolutely not. Only specified brake fluid (DOT 3, DOT 4, DOT 5, etc.) must be used. It is specially formulated to have a high boiling point (to prevent vapor lock), stable viscosity across temperatures, and compatibility with the system's seals. Using the wrong fluid can cause catastrophic failure.

Common signs include: a soft or spongy brake pedal, the pedal sinking to the floor, increased stopping distance, a brake warning light on the dashboard, visible fluid leaks near the wheels or under the car, or a grinding noise (which often indicates worn brake pads making contact with the disc or drum).

A braking system in which force is transmitted from the brake pedal to the brake mechanism using a fluid.

Hydraulic brake is usually technical in register.
