An anti-spin brake energizer includes a friction member pivotally mounted adjacent a brake rotor. A solenoid urges the friction member into engagement with the rotor in response to a spinning wheel condition. The engaged friction member wedges between a piston and the rotor and wedges the piston away from the rotor. The movement of the piston away from the rotor generates a fluid pressure signal in a chamber communicated to the brake to retard the rotation of the rotor to thereby eliminate the spinning condition. A relief valve communicates the chamber with the master cylinder to terminate the fluid pressure signal in response to deactivation of the solenoid and to permit return of the friction member to its rest position spaced apart from the rotor.
