Bowmonk BrakeCheck Truck & Trailer
The BrakeCheck TT (Trailer Test) is very similar to the standard BrakeCheck unit, but has the facility to display separate results for the truck and trailer braking efficiencies.
Please note that, as with any portable brake testing device, the BrakeCheck TT is not DVSA-approved for trailer brake testing. To gain DVSA approval a test device must be able to determine whether the wheels have locked up, which is not practically possible with a portable device. BOW820 - BrakeCheck TT Stores 99 Service Brake, 99 Hand Brake and 99 Trailer Brake tests into memory.
