The invention relates to a brake arrangement (300) for a tracked vehicle (V). The brake arrangement (300) comprises a brake housing (310). Said brake arrangement (300) is journaled in bearings in connection to a drive unit driven drive axle (40) configured to rotate a drive wheel member (DW). Said brake arrangement (300) comprises a set of ring shaped friction elements (350) arranged about said drive axle (40) and configured to be pressed together in the axial direction for providing a braking function. Said brake arrangement further comprises a ring shaped parking brake piston device (370) coaxially arranged around said drive axle (40) in connection to a radially outer portion of said set of friction elements (350). Said parking brake piston device is configured to provide pressure in the axial direction against said radially outer portion of said set of friction elements (350) based on a parking brake action so as to press said elements together for preventing rotation of said drive axle (40), preventing movement of drive wheel member (DW).
