Anything really wrong with sanding the back end of a non self timing brake until it’s timed properly? I plan on using wet/dry sand paper over a sheet of glass. How real a chance do I stand of screwing up concentricity if I go this route? Seems like a better option than shims or crush washers, right? Talk me into or out of this plan.
I've done that before and had no problems. Fine wet/dry over a smooth granite tile. Just be careful to go slow and use even pressure, rotating the brake between strokes.
