Development status of automobile brake industry
With the development of science and technology and the development of automobile industry, especially the development of military vehicles and military technology, new breakthroughs have been made in vehicle braking, and hydraulic braking is another important innovation after mechanical braking.
The modern automobile brake development originated from the original mechanical control device, brake control the original driver just a set of simple mechanical device applied force to the brake, then the weight of the car is relatively small, relatively low speed, mechanical braking has been able to meet the needs of automobile brake, but with the increase of the car's own weight, and power for more on the mechanical brake device is very important. A vacuum assist device began to appear.
In 1932 the production of weight of drum brake 2860kg Cadillac V16 car four wheel with the diameter of 419.1mm, and a vacuum booster brake pedal control.
The Lincoln Company also launched the V12 sedan in 1932, using a drum brake operated by four soft cords to control the vacuum booster.
