Clicking noise...mmm...well, it might just be a bit of valve noise, probably not anything serious. Lasts maybe a min? If it's loud though, that would be problem.

A bit of noise first time using the breaks for awhile. If you had rain, went through a puddle, etc then it could just be a bit of rust on the rotars. When ever it rains and my cars out I get some noise. Do you use your parking brake? Perhaps it's not releasing fully and making some noise.
