Last night I was laying in bed and a horrible thought popped into my head. I have just switched from Shimano to Campy and I haven't taken the time to look at my brake adjustments. I was picturing myself getting a flat tire and not knowing how to adjust the brake, so I could remove the wheel and fix the flat. This morning before work I took a quick look at my bike and sure enough, it's not like my old Ultegra brake. There's no lever that expands the brake so the wheel can be removed. I'm sure it's there somewhere, but I didn't take the time this morning to figure it out. How do you adjust the brake, so you can remove the front or rear wheel to change a flat? Thanks a lot.
