A brake control arrangement and a method for braking a motor vehicle. Auxiliary brakes (8, 9) of the vehicle are automatically controlled during an initiated automatic braking operation so as to endeavour to restrict the vehicle speed to a reference speed. Frictional wheel brakes (2) of the vehicle are automatically activated to apply a braking effect on at least one pair of wheels when the following conditions are simultaneously fulfilled during an ongoing automatic braking operation: it is established that the vehicle speed exceeds a given threshold speed, which threshold speed is higher than the reference speed, and it is established that the braking power of one of said auxiliary brakes is restricted in such a manner that this auxiliary brake is not allowed to exert the maximum braking power exertable by it at the prevailing speed of the vehicle engine or the prevailing speed of the propeller shaft. |
