A pinched brake hose can prevent an air brake from fully engaging. It is important to examine the entire brake system as part of any inspection.
Every wheel end assembly on a truck has an air brake. Each and every one of them needs to be checked during an inspection.
Ruhl Forensic has developed a working air brake model that shows the brake components and the effects of brake adjustment on stopping.
Air Brake System
Investigating a heavy vehicle accident includes careful inspection and knowledge of the air brake system. A full analysis of the brake system at the time of the crash can give insight into the vehicle’s performance, i.e. stopping distance, vehicle dynamics, etc.
Ruhl Forensic has designed and developed an electronic air brake tester that increases the amount of pertinent data that can be obtained from an air brake system evaluation. The electronic brake tester allows analysis of brake system timing which can be a crucial element in many loss-of-control situations.
The FMCSR requires the driver to do a pre- and post-trip inspection. Brakes are a significant part of that inspection. The motor carrier is required to document the inspections via a driver's Daily Vehicle Inspection Report, (DVIR). The forms show that the inspections are taking place and the maintenance is performed properly and documented.
Technical terms can confuse a jury when it comes to understanding how the air brake system on a commercial vehicle works. To assist them, Ruhl Forensic has developed working air brake models that can be utilized in the courtroom. The models demonstrate the function of the various brake components and the effect brake adjustment has on stopping a commercial motor vehicle.
