On-Vehicle Brake Evaluation Test System
On-Vehicle Brake Evaluation Test System
Model 1420

The Greening Model 1420 On-Vehicle Brake Evaluation Test System provides the ability to measure and report disc brake rotor inboard and outboard surface run-out, disc thickness variation (DTV), and break-away and residual brake drag torque. The self-contained, constant speed drive system and in-line torque transducer enables repeatable sequence control and accurate reporting of drag torque values. The Universal Wheel Drive Adapter fits all wheels, independent of the number of wheel lugs. Our unique design provides constant speed independent of drive adapter alignment and eliminates the need for optical alignment devices.

An intuitive operator interface makes the system easy to use and automatically generates the test report in both graphical and tabular formats. The signal conditioning rack and other sensitive electronic components are mounted in a rugged, portable cart with heavy-duty lockable casters for ease of positioning.
