[0002] When a car is in use, it needs to be inspected regularly to ensure that all functions of the car are normal and can continue to be used. Depending on the age of the car, the time and items of the inspection will also change.

[0003] According to the items that need to be tested, a variety of automobile testing equipment has been invented in today's society, including automobile brake testing devices, speedometer test benches, automobile lighting testing devices, automobile chassis dynamometers, etc.

[0004] The automobile brake detection device is an auxiliary device used for automobile brake detection. It has been widely used in the field of automobile brake detection.

The clamping limit of the rear wheel turns on the first motor 27. Under the deceleration action of the reducer 25, the active roller 23 drives the front wheel of the car and the driven roller 22 to rotate slowly. At this time, the car is braked. The resistance received by the active roller 23 is transmitted to the inside of the torque sensor 24 to obtain the specific information of the braking function. The information is then converted into intuitive numbers and displayed on the brake data display screen 3. After the test is completed, the car is driven out from the top of the device, and the second motor 53 is output in the reverse direction to retract the wheel limit block 59 for the brake test of the next car.
