PCT No. PCT/SE96/01570 Sec. 371 Date May 29, 1998 Sec. 102(e) Date May 29, 1998 PCT Filed Nov. 29, 1996 PCT Pub. No. WO97/20150 PCT Pub. Date Jun. 5, 1997The present invention relates to a brake device comprising a number of brake discs, brake pads and brake pad holders being arragned for mutual co-operation after axial operation by means of actuators for braking. The brake pads are being carried by the brake pad holders that are connected to a first frame member. Ring shaped brake discs are carried by a second frame member. Brake pad holders and brake discs ate axially displaceable journalled relative to each other. The two frame members are arranged to be braked relative to each other actuation of axially acting actuators. In order to provide efficient cooling of the parts that comprises the brake, there are a number of passages provided in the brake drum for leading air internally to the brake system when the drum and the wheel rotates in the direction of travel.
