Yes and no. There is, depending on the cable. If you get an OEM cable, than it is just three or four slow pushes of the pedal, and then make sure the FW adjustment is still good. It should be checked for proper adjustment every few days for a few weeks when it's new. A non OEM cable will never get through the "brake in period", it'll need to be checked for adjustment every few days until the day you break it.
It's nothing like breaking in an engine or a clutch though- like Hissen said... just put it in and drive the wheels off it. It needs to be checked on regularly, not babied
Jess, good point about checking the adjustment frequently. i managed to omit that one.
Sirsureshot, it is common knowledge that people are a little groggy when they first wake up - sometimes they dont read and comprehend as well while in this 'waking up' or 'break-in' period.
it was great advice, though.
