A power braking system consists of several distinct components, including the vacuum booster, master cylinder, brake fluid reservoir and lines, and calipers (or drums). Power brakes have been around in some form since the 1920s, and since the late 20th century all cars sold in North America have been equipped with power brakes.
A burnout (also known as a peel out, power brake, or brakestand) is the practice of keeping a vehicle stationary and spinning its wheels, the resultant friction causing the tires to heat up and smoke. While the burnout gained widespread popularity in California, it was first created by Buddy Houston, his brother Melson and David Tatum II at Ted ...
In the US it is commonly called a brake booster. A vacuum servo, also known as a power booster or power brake unit, uses a vacuum, usually supplied by the engine, to multiply the driver's pedal effort and apply that effort to the master cylinder .
When a driver steps on a brake pedal, the kinetic energy of the moving car is turned into friction between the brake pads and rotors (at 60 mph, there’s enough energy in a 3500-pound car to keep ...
The brake balance or brake bias of a vehicle is the distribution of brake force at the front and rear tires, and may be given as the percentage distributed to the front brakes (e.g. 52%) [1] or as the ratio of front and rear percentages (e.g. 52/48). [2]
The braided wires have negligible expansion under pressure and can give a firmer feel to the brake pedal with less pedal travel for a given braking effort. The term 'power hydraulic brakes' can also refer to systems operating on very different principles where an engine-driven pump maintains continual hydraulic pressure in a central accumulator.

(The pedal on the left is the parking brake). In modern cars the four-wheel braking system is controlled by a pedal to the left of the accelerator pedal. There is usually also a parking brake which operates the rear brakes only (or less commonly, the front brakes only, as in the Saab 99 and in the Citroën Xantia).
