ABSTRACT:
A roller type brake testing device is disclosed which incudes two pairs of cradling rollers for supporting and applying a driving torque to two wheels of a vehicle such as an automobile. The testing device includes a pneumatic lift mechanism for selectively raising and lowering the rollers which engage the rear portion of the wheels and through which driving torque is applied to the wheels. The brake tester may further include an indicator such as a pressure gauge for displaying a measure of the weight of the axle supporting the vehicle wheels to guide the operator in applying the brakes to achieve a braking effort correlated with axle weight.
