Mobile Performance Based Brake Tester (PBBT)

EDR / HVEDR Data Analysis

Photogrammetry Analysis

PBBT’s allows a brake inspection to go above and beyond a visual inspection or mechanical inspection that is limited to the air brake chamber stroke measurement. The use of a Performanced-Based Brake Tester (PBBT) provides an actual quantitative measurement of the amount of brake force being generated at each braked wheel in 20 minutes or less.

The use of a PBBT as reported by the Commercial Vehicle Safety Alliance (CVSA) can help a fleet determine the following:

  • ● Evaluate which brake linings are appropriate for a fleet’s operations
  • ● The sources of uneven brake lining wear
  • ● Possibly determine the source of uneven tire wear
  • ● Root cause of air valve problems and other air system problems
  • ● Brake balance problems
  • ● Whether or not a vehicle involved in an accident had adequate braking capability
  • ● Whether or not the vehicle meets the minimum Department of Transportation (DOT) regulated brake performance standards

The Performance-Based Brake Tester (PBBT) is a dynamometer that can make direct measurements of brake forces at each axle end of a vehicle.
