New IPA #9107B Electric Brake Force Meter (3rd Gen) - Trailer

In this review the New IPA #9107B Electric Brake Force Meter (3rd Gen) is evaluated for technicians and vehicle owners who need to diagnose towing systems without a trailer. The bottom line: this tool is best for anyone who routinely services or troubleshoots trailer brake controllers because it reliably simulates trailer load and provides clear diagnostics, saving time and letting a single person test while driving. The review focuses on real-world use, practicality, and whether the patented simulation and long cord justify adding it to a mobile shop or home toolbox.

Key Features

• Trailer brake simulation: Accurately mimics trailer brakes so tow vehicles can be tested without attaching an actual trailer, which simplifies diagnostics and saves setup time.
• Patented compatibility: Works with both integrated and aftermarket brake controllers, improving the odds of getting reliable, controller-specific results during troubleshooting.
• Lighting and circuit tests: Tests all lighting circuits and electric brake systems to pinpoint wiring faults and faulty connections before they become road hazards.
• 25-ft cord for solo testing: The included 25-ft cord allows for one-person operation and test-drive functionality so the driver can simulate braking while observing controller behavior.
• Soft nylon storage case: Comes with a compact soft case for easy storage and transport, keeping the unit and cord protected between jobs.

Who It's For

The New IPA #9107B is ideal for mobile mechanics, fleet maintenance personnel, RV owners, and anyone who frequently inspects or installs electric brake controllers and wiring. Its simulation capability and long cord make it particularly useful when testing while driving or when a second person is not available.

This is not targeted at casual owners who never tow or who only need a basic circuit tester; those users might prefer a simpler lighting tester or multimeter. Professionals and hobbyists who require accurate brake-force simulation and controller compatibility will get the most value.

Pros & Cons
