NEVER EVER try to bend Universal Brake Calipers. Learned that lesson about 1974. I tried to toe in a Universal 61 on a customer's bike and the arm snapped clean off. Fortunately we had a box full of those calipers and I replaced the broken one.
I use an 8" adjustable wrench (Crescent wrench) with tape wrapped around both jaws to reduce damage to the calipers.
