Sorry I get what you were saying now! Just so you know the spacers are part of avids tri-alighn system, they are not for spacing, but rather for alighning the caliper so when the pads touch they are flat. Other systems such as tektro, etc... use a slightly different systemm where the pads themselves can rotate slightly which alighns them, so the actual caliper is easier to alighn and do not need the spacers.
