EPB——electrical parking brake calipers, is the advanced products from traditional parking brakes, using an electrical motor to provide the braking force. 
We are also continuously developing this range for aftermarket. 
For those products, the quality of the motor is essential. Top-level motors are applied in our EPB calipers.
We also have several special tests such as clamping force test and life test to check and promise the quality and performance of both those EPB calipers assembly and individual motors.
