Many different types of vehicle brake system, brake system, the traditional structure of the main types of mechanical, pneumatic, hydraulic, gas-liquid hybrid. Hydraulic brake technology is now the most mature and most economical braking technology, and apply to the current on most passenger cars. Currently, almost all cars use friction brakes, the drum and the disc can be divided into two categories. The main advantage of disc brakes at high speed braking when the brake quickly, heat better than drum brakes, brake performance constant good, easy to install as advanced electronic devices like ABS. Electromagnetic disc brake is a friction-type electronically controlled brakes, currently used in the trailer brake on a particular car, but with the cars development, high dynamic performance breakthrough in automotive technology, automotive braking systems will occur change, while the electromagnetic brake is the principle of electromagnetic resistance to the vehicle kinetic energy into heat consumption to achieve the brake, electromagnetic brake of the security, flexibility, simplicity, operability, will
