PC-BRAKE AIR is the premier accident reconstruction tool when the braking effectiveness of airbrake-equipped trucks such 10-wheelers, 18-wheelers or tractor-trailer-trailer combinations is involved. Left-to-right brake imbalance, disc, wedge or S-cam brakes, proportioning valves, temperature brake fade, push-rod force decrease due to push-rod travel, and all major suspension designs can be analyzed. Dynamic axle load transfer as well as inter axle load transfer are analyzed. The effects of longitudinal loading differences (liquid loads) can be analyzed in terms of braking effectiveness, axle loadings and brake lockup. Accident scene data in terms of wheel and/or axle lockup can be analyzed. Electronic computer data printouts can be analyzed more effectively in terms of brake application, wheel lock and change in speed (deceleration).

What if questions such as could the offending car have cleared the area of impact if the brakes of the truck/trailer had been in proper adjustment can now be answered accurately.

A critical question experts often are confronted with concerns the most probable deceleration and hence after impact speed - of a commercial vehicle with defective or poorly maintained brakes can now be answered scientifically.

Truck run-away accidents may be analyzed more accurately with respect to
the mechanical condition of the brakes.

 

Tractor-trailer jack-knifing can be analyzed accurately in terms of potential tractor rear axle lockup and loading configuration. The effects of inter axle load transfer of walking beam and four-leaf spring suspensions can be evaluated in terms of truck deceleration at first brake lockup.

PC-BRAKE AIR
is an expanded and fully updated version of the first computer program developed more than 30 years ago for air brake systems for commercial vehicles to have included dynamic axle load transfer, brake fade and push-rod travel effectiveness developed by Dr. Limpert while at the University of Michigan.
