Brake test on a single-axle brake dynamometer
Brake test on a single-axle brake dynamometer
We recommend use of a brake test dynamometer with controlled roller speed and a maximum test speed of 5 km/h.
Failure to so could result in braking intervention by the EDL system.
In this case the engine and the ignition should be switched off for the test. If necessary, run the engine briefly to ensure that enough vacuum is built up for the brake test.
