Zusammenfassung:	The invention relates to a device for eliminating the risk of vehicle wheel locking at braking. According to the invention, on the spring suspension (U) of the wheel (H) in question an accelerometer (G) is attached, which at the passing of the vehicle over road irregularities emits a decaying A.C. signal (S) with information on oscillations of the axle (A) and damping of the tyre. After having been passed through a rectifier (in FL) and a derivating circuit (DVR) the signal (Sd) is a measure of the variations in the tyre damping. A tendency of skidding (locking of the wheel), which sudden reduction in the ground braking moment of the wheel expresses itself as an abrupt reduction in the damping of the tyre, produces a spike in the signal. The signal (Sd) is fed to a means (R) controlling the braking force (B) and capable to momentarily reducing the braking force when a spike occurs. It is hereby ensured that the braking force always is maintained at a value eliminating the wheel locking risk.
