Step 1
Vehicle's front tires are positioned between the VIS-Check rollers. VIS-Check determines brake performance and measures:
- Axle Weight per Wheel
- Wheel Rolling Resistance
- Service Brake Application Timing
- Service Brake Air/Hydraulic Pressure
- Service Brake Release Timing
- Calculates Vehicle Stopping Distance
- Brake Balance Left to Right & Front to Rear
Step 2
Vehicle's front tires are positioned on VIS-Check Wear Detection Plates. A hydraulic jack lifts some weight off of the front axle. The plates move front to back and side to side. VIS-Check allows the technician to observe the dynamic condition and integrity of:
- All Front Axle Steering Linkage Components
- All Front Axle Suspension Components
- Engine & Chassis Mounts
- Wheel Bearing Movement
Step 3
Vehicle's rear axle tires are positioned between the VIS-Check rollers. VIS-Check determines brake performance and measures:
- Axle Weight per Wheel
- Wheel Rolling Resistance
- Service & Parking Brake Application Timing
- Service & Parking Brake Air/Hydraulic Pressure
- Service & Parking Brake Release Timing
- Brake Balance Left to Right & Front to Rear
Step 4
Vehicle's rear drive axle tires are positioned on the VIS-Check Wear Detection Plates. A hydraulic jack lifts some weight off of the inspected axle. The plates move front to back and side to side. VIS-Check allows the technician to observe the dynamic condition and integrity of:
- All Rear Drive Axle & Suspension Components
- Chassis Component Integrity
- Fifth Wheel
- Wheel Bearing Movement
- Driveline
- Chassis & Body Mountings
- Inspect trailer or Special Axle configurations as detailed above.
Step 5
Inspect trailer or Special Axle configurations as detailed above.
Step 6
VIS-Check machine operator prints out detailed brake performance graphs and reports for all wheel positions. The technician prepares a complete vehicle status report and makes recommendations based on the performance reports and dynamic visual inspections.
