Removed Mower deck. Bolts were rusted and had to soak bolts with penetrating lubricant. Bolt to one arm had loosen but did not hold brake arm. Had to remove assembly and finally removed bolt. Replaced self tapping bolt with new bolt and added 2 washers, lock washer and nut. After 2 hours completed project and mower works great
