Pro-Cut's GYR vbs (validated brake service system) guides technicians through the entire rotor matching process, insuring that discs can be matched to industry specs. The finished metrics (rotor thickness and run-out) of each rotor are captured and saved to the on-board tablet and the Cloud. In addition, color-coded customer reports are available for print-out. The system includes a bar code scanner, tablet computer with GYR application and Pro-Cut in either the PFM 9.2 or Warthog model. The GYR vbs works in this sequence: The VIN is transmitted via barcode scanner and the GYR application pulls the rotor specs for the vehicle. The system then saves the metrics of each finished rotor.
