If you have pulled the brake cover off so it now does not engage with the brake handle, you will have too lever it off away from the drum, this sounds bad but it is now the only way to remove it. Once removed you can either make a three legged tool to fit into the quadrant to load the brake, or remove the clutch and drum so as you can put the brake back onto the saw and use the hand guard to load it, with the clutch and drum removed it will fit freely back onto the saw. You could also remove the hand guard from the saw and use this as a loadind tool.
