Brake check on single-axle roller dynamometer

Brake check on single-axle roller dynamometer

The drive is provided by the dynamometer.

Important

● The dynamometer rollers must rotate at a minimum speed of 3 km/h and a maximum speed of 6 km/h.

Brake dynamometers offered by Workshop Equipment fulfil these requirements.

Brake check procedure

♦ Drive vehicle with axle to be checked onto rollers of dynamometer.

♦ Select “N” position or “Neutral”.

♦ Proceed as prompted by dynamometer.

Checking electromechanical parking brake

Checking electromechanical parking brake

Activate “test mode”:

Important

● No faults influencing function of roller dynamometer (e.g. rotational speed sender fault) detected

● Seat belt is fitted

● Rear axle on single-axle roller dynamometer

● No gear engaged

● Ignition is on (at least 3 seconds)

● Front wheels must be stationary (at least 3 seconds)

● Rear wheels must rotate for at least 3 seconds at a constant speed between 2 km/h and 9 km/h.

When entering “test mode”, the yellow electric parking brake and handbrake fault warning lamp -K214- will light up.

In “test mode”, the electromechanical parking brake does not close fully when the button is pressed initially.

The tension is increased gradually by actuating the electromechanical parking brake button -E538- two times in succession.

♦ Initial actuation: both sides of parking brake are actuated to the point of application

♦ Second actuation: both sides of parking brake are fully applied

Terminating “test mode”:

As soon as one of the preconditions for the “test mode” is no longer fulfilled, the “test mode” is immediately terminated, for example:

Important

● Front wheels: speed over 0 km/h

● Rear wheels: speed under 2 km/h or over 9 km/h.
