A coaster brake assembly which is coupled directly to a drive shaft. The drive shaft has a threaded driver integral thereon. A clutch cone having internal threads traverses in axial directions as it threads on or off the driver depending on the rotation of the driver. A brake cone is provided which has a smooth axial bore through which the drive shaft rotates. The axial movement of the clutch cone toward the brake cone operates to force brake shoes against the inside wall of the hub. A spring is provided to facilitate threading action between the clutch cone and the driver.
