A brake testing apparatus comprises at least one pair of motor-driven rollers on which a wheel having a brake to be tested is mounted. A leaf spring is attached at one end to the motor stator and its free end is held between opposed abutments so that when the wheel is braked, a reverse torque in the stator induces a stress in the leaf spring.
