3.4 Ovality Test
The out-of-round of drum or disc brakes can be judged with this measurement.
The ovality can be read on the pointer deflection. The difference between the highest and the
lowest pointer value is then the ovality in kN.
3.4.1 Ovality test without Remote Control
1 Drive onto roller set with desired axle..
2 Apply brakes with average force (approx. 1 kN, vehicle-dependent).
3 Hold for approx. one wheel revolution
4 Ovality is read on the pointer deflections.
The difference between highest and lowest pointer value is the ovality in kN.
3.4.2 Ovality Test with Remote Control
1 Drive onto roller set with desired axle.
2 Apply brakes with average force (approx. 1 kN, vehicle-dependent) and hold.
3 Press ovality key on remote control and hold for 1 wheel revolution minimum.

Ovality key
4 Release the ovality key on the remote control.
5 Release brake pedal.
If brake force is not held constant during measurement or if ovality key is not pressed for
an entire wheel revolution false test values will be the result due to “artificially induced“
out-of-roundness.
The ovality value is automatically stored together with the respective axle when storing the max.
brake force.
