An adjusting device is disclosed for the brake shoes of inside shoe brakes. The adjusting device includes two levers which are articulated on a carrier at a lateral distance from one another. The levers each engage on one of two adjacent brake shoe ends and are jointly in engagement with a frustoconical endpiece of an actuating member guided rotatably on the carrier in a threaded bore provided between the levers and extending in parallel with a brake drum axis. During the rotation of the actuating member for the adjustment of the brake shoes, the two levers are pivoted in directions opposite to one another, being supported respectively on one of two mutually opposite edges of the brake-shoe webs so as to surround these. The adjusting device is merely attached by its levers on to the brake shoe webs so it can also execute self-reinforcing floating movements of the brake shoes in dual servo-brakes.
