Type approved vehicles require a brake reaction test. The brake reaction test ensures the time taken for the brakes on the trailing vehicle to be applied, after the driver has applied the brakes, is with in European regulations. Slow brake reaction times increases the distance a vehicle travels before coming to a stop. Common causes of poor reaction time are:
- Incorrect brake pipe diameters
- Location of valves on the trailer
- Distance between valves
- Incorrect air tank reservoir size
- Too many elbow fittings in piping circuit, excessively long air pipes.
Granning can organise and assist in performing brake reaction time tests on vehicles to comply with European brake regulations.
