The Bowmonk BrakeCheck Secondary is a purpose-built, portable brake decelerometer designed to measure brake performance on HGVs, PSVs, buses, and large commercial vehicles.

This model provides dedicated Secondary Brake testing, while also measuring Service Brake and Handbrake performance.

Each brake type stores one test result only, making this unit suitable for individual vehicle testing rather than multi-vehicle fleet inspections. Secondary brake systems are a separate legal requirement on many heavy vehicles and must be measured independently as part of a preventative maintenance programme.

The BrakeCheck Secondary is specifically designed to measure secondary brake performance accurately, while still allowing service and handbrake testing using the same device.
