I just noticed that my Felt bike's front caliper appears to have a bit wider opening between the pads than the rear caliper. Both calipers are in the "closed" position for normal use (the cam lever to help when removing wheels is in the down/closed position). As a result I have to pull the front brake lever a bit more than the right one before the pads actually make contact with the rim brake surface.
Do caliper brakes have an adjustment for how far apart the pads are? I read through the rim brake page on Sheldon's site but didn't see anything about adjusting the pad opening on caliper brakes.
