1.    High efficiency
2.    Brake chamber size is small, charging and discharging very fast
3.    Save energy
4.    Automatic clearance adjust mechanism to ensure can match with good braking force, stable direction and stable braking during using.
5.    using floating tellurium structure, torque output of braking is stable.
6.    Good braking mobility 
7.    reduce noise 
8.    improve thermal stability and high-speed braking performance because of small brake drum dimension, wide brake pad and good heat elimination condition, and create conditions for using small tires
9.    small variety of components, and numbers of components are small
10.    Good interchangeability and universality is convenient for making seriation
