Enhanced Braking

New federal braking regulations for heavy trucks

The primary benefit of PBBTs is that they provide an objective, consistent and standard measure of the as-is braking performance of a vehicle, says CVSA, whereas a visual inspection examines a vehicle for the presence and appropriate functioning of physical components. While a visual inspection can indicate a potential problem with a brake component, in practice the actual brake performance can never be determined by visual inspection.

One type of PBBT combines braking testing with a diagnostic tool for fleet brake and tire management - the VIS-Check Fleet Program PBBT, from service automation provider Vehicle Inspection Systems. Based on its VIS-Check undercarriage diagnostic system, the machine can be used to determine brake system effectiveness, as well as tire pressure, tread profile and wear by individual wheel end, on Class 3 through 8 vehicles.

Link-Radlinski is an independent testing and engineering consulting firm that develops and markets brake-testing equipment and conducts certifications testing for many original equipment manufacturers. Its ABS testing system has become the industry standard for end-of-line testing in truck and bus manufacturing plants in the U.S., Mexico and Canada, and its roller brake testers are used by a number of vehicle and brake manufacturers for research and development work. Link-Radlinski also has mobile and permanent brake and ABS testers and will travel to perform on-site testing.

Several other companies can provide PBBTs, PBBT test service and on-site vehicle inspections, including Hunter, Infinity and Maha.
