Abstract: Disclosed is a brake arrangement for a tracked vehicle. The brake arrangement comprises a brake housing. Said brake arrangement is journaled in bearings in connection to a drive unit driven drive axle configured to rotate a drive wheel member. Said brake arrangement comprises a set of ring shaped friction elements arranged about said drive axle and configured to be pressed together in the axial direction for providing a braking function. Said set of friction elements comprises a first end friction element being the outermost friction element against which pressure is configured to be provided for said braking function. Said first end friction element has a thickness in the axial direction which is thicker than the remaining set of friction elements so as to facilitate distributing an even pressure on said set of friction elements when said set of friction elements are pressed together for efficient friction braking function.
