A brake is primarily a safety device. There are already enough things that can go wrong with them. If brakes fail, the consequences (face plant, soiled underwear, hospital food, life in a wheel chair) are not really worth the small savings made, so I would just buy a new brake or at least the correct pivot bolt.
