disc brake question.
 

i haven't been on this site in a while.

i just upgraded because i think i got a great deal on a 2014 specialized roubaix expert DI2 hydraulic disc brake bike. the only reason i bought this bike was because it has electronic shifting, i always wanted a bike with this, and was in my mind CHEAP, $1500. it is used but seems to be a solid bike. it has some paint scratches and it looks to have been in storage for years so it needs a serious clean up.

my current bike that i ride is a 2010 specialized roubaix elite


my question is regarding the disc brakes. first the front brake seems to drag a bit and the second is the brake lever go 3/4 of the way to the bars before they work. this seems to me as excessive travel. are they supposed to go that far before engaging? and how do i adjust the pads to stop the drag? or better yet where can i find info on how to service the brakes?


the 3rd question once i have everything sorted out. is travel. i have a seasucker bike rack where you remove the front wheel to put it in the rack. do i have to worry about the brake pads falling out during transport?


THANKS for the replies in advance.

1, center the calipers... youtube is your friend
2. probably needs to be bled... youtube is your friend
3. no.. they are held in my a pin/screw.

THANKS for the fast reply.
i have been doing some google searching and centering seems to be the solution.

also with my searching it seems to suggest the brake fluid should be flushed out due to sitting for so long.
