Abstract

The invention relates to a device and a procedure that distribute a braking effect in a vehicle. The vehicle contains a main brake (1a, b) that allows braking of the driven (3) and undriven wheels (2) of the vehicle, an auxiliary brake (4, 8) that allows braking of the driven wheels (3) of the vehicle, and a control unit (13) that is arranged to distribute the requested braking effect so that the auxiliary brake (4, 8) is activated in the first instance to provide the requested braking effect. When the braking effect of the auxiliary brake (4, 8) is insufficient, the control unit (13) activates the main brake (1a, b) to provide a supplementary braking effect. The control unit (13) is arranged to apply the braking effect of the main brake (1a) to the vehicle's undriven (2) wheels in the first instance and when a braking effect of a decided value (v) has been applied to the undriven wheels (2) the control unit (13) is arranged to apply the braking effect also from the main brake (1b) to the vehicle's driven wheels (3).
