PURPOSE: A calibration device of vehicle braking tester is provided to improve the reliability of a brake tester by comparing a measured value with a target brake force value which is theoretically obtained. CONSTITUTION: A calibration device of vehicle braking tester(100) comprises a gear-box(102), a brake roller(104), a driven roller(105), a connection link(106), and a load cell(107). The gear-box is installed on the bottom surface of the device. The brake roller is installed in the gear-box and is contacted with the wheel. The driven roller is positioned corresponding to the driven roller. The load cell is installed between the end of the connection link and the bottom surface of the device.
