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.

A joint element provided with a swing dampener element and comprising a first joint part, a second joint part, and a swing dampener brake. The second joint part comprises a second end part which is detachably fixed to a first end part of the second joint part by a joint part coupling which is adapted to allow the second end part to be moved in an axial direction to a detached position in relation to the first end part, the detached position allowing replacement of active components of the swing dampener brake while the first end part remains bearing-mounted to the first joint part, the active components of the swing dampener brake comprising at least one first brake disc member and at least one second brake disc member.

A spring applied hydraulic release caliper brake includes a housing carrying springs acting on a piston in a default position. The housing further carries an adjuster, with an outer portion of the adjuster being in direct contact with an outermost spring of the springs. A released position of the brake includes the piston being in contact with the adjuster. The adjuster is adapted to rotate a predetermined amount to thereby cause the adjuster to act on the springs. This removes an amount of clearance between the piston and a stator, such that the removal of the amount of clearance becomes a new default position for the spring applied hydraulic release caliper brake.

A hydraulic fluid pressure operated torque transmitting assembly for use as a brake or clutch which utilizes hydraulic pressure operated cylinders in a housing moveable with respect to an axially stationary spring housing to move a pressure plate against rotating discs and reaction plates. Hydraulic fluid pressure disengages the torque transmission and loss of hydraulic pressure enables springs in the spring housing to move the pressure plate to engage the friction discs for torque transmission. Radially removable spacers permit the spring housing position on mounting studs to be adjusted for compensating for friction disc wear. The hydraulic cylinders each have a drain port communicating with an annular collector groove in the cylinder bore. The drain ports are interconnected through flexible conduits connected to a master drain port in the cylinder housing.
