A brake system that employs vacuum or hydraulics, to assist the driver in application effort.

Brakes operated by mechanical, hydraulic or pneumatic power rather than by driver effort.

An automotive braking system in which the force applied to the brake pedal is amplified by means of engine vacuum or hydraulic force from a pump.

A brake system that uses assistance (usually from a vacuum) to augment the force applied by the driver.

Incorrect alternative to Power-Assisted Braking. Power brakes are correctly those in which a steady, high-pressure supply of oil actuates the mechanism. When the driver lightly touches a pedal, the mechanism opens the valve controlling the brakes.

A power booster that utilizes vacuum or hydraulic pressure to boost the braking effort of the driver. Tapered Roller Bearing - A bearing that uses a series of tapered steel rollers held between inner and outer races.

A brake system that uses a power booster to make braking easier.

use a vacuum to add additional force to the brake actuating mechanism. Less effort needed on the brake pedal.
