Electronic Repairs & Chip Transfer
- • Mecanica’s forensic electronics/electrical team has extensive experience in recovering data from damaged electronic assemblies including Electronic Control Units (ECU) whose memory chips may contain “blackbox” or Event Data Recorder (EDR) data.
- • ECU’s can be damaged due to vehicle crush or thermal damage from fire, or water damage due to submersion.
- • Mecanica’s electronics lab team are certified by IPC for 7711c and 7721c – Rework, Modification and Repair of Electronic Assemblies

Mobile Performance Based Brake Tester (PBBT)
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.
