Beschreibung
Zusammenfassung:	An actuation mechanism for a disc brake is provided. The actuation mechanism comprises:a non-rotatable yoke to transmit an actuating force from an operating shaft;a piston configured to be driven by the yoke to transmit the actuating force to a brake pad, the piston comprising a portion rotatable with respect to the yoke to cause the piston to extend; anda wear adjustment mechanism for adjusting extension of the piston to account for wear of the brake pad, the wear adjustment mechanism including a driving portion configured to be driven by the operating shaft, to transfer torque from the operating shaft to the rotatable portion of the piston to cause the rotatable portion to rotate and extend the piston,wherein a rolling element bearing is located between the driving portion of the adjustment mechanism and the yoke.
