my brake lever seems to have quite a bit more play in it between riding in to work this a.m. and taking a trip out on the highway. the lever is almost to the grip before the front brake really starts to bite well. is this part of the whole 'breaking-in' process, or should i have my brakes looked at. pumping them didn't seem to have any effect and it's chock full of fluid. . . air in the line maybe?
