A vehicle spindle test fixture that permits applying a brake load torque to the spindle or test unit has a loading actuator that will permit high input force levels, while keeping the coupled mass that must be moved during the test operation at a reasonably low level. In testing a vehicle spindle ideally, the mass carried by the test spindle would be equal to the wheel and tire. Because of larger physical sizes, the linkage design problem has become more difficult. The present invention reduces the total coupled mass for brake torque testing by utilizing a unique linkage arrangement that reduces the size of the input used for brake torque.
