。 A plurality of brake tester units each including a pair of rollers on which a wheel can be placed, a roller drive means capable of driving the rollers, and a braking force sensor capable of detecting the braking force of the rollers; In a brake tester equipped with a controller that stores and calculates input signals and determines whether the braking force is acceptable or not based on a judgment value that stores this information in advance, the outer peripheral surface of the roller is provided with a low-friction peripheral surface. In addition to providing a high friction peripheral surface, a means for varying the circumferential speed of the roller is provided, and when measuring the maximum braking force of the vehicle, the wheels are placed on the high friction peripheral surface of the roller, and the peripheral speed of the roller is driven at a relatively low speed. On the other hand,
When determining the functionality of a vehicle's anti-lock braking system, wheels are placed on the low-friction surface of rollers.
A brake tester characterized in that the roller is driven at a relatively high circumferential speed.
