Brake test on single-axle roller dynamometer

We recommend use of a brake dynamometer with controlled roller speed and a max. test speed of 6 km/h.

Failure to comply with the above specifications can lead to brake application (EDL control).

In such cases switch off engine and ignition for test purposes. Run engine briefly if necessary to build up sufficient vacuum for brake test.
