dumb question number 9999

ok so i guess a bit more info is needed. i replaced the front brake lines cause they went bad due to dry rot, well there i did check everything else and it did seem to be fine. also it does tend to go back to straight, the pull is pretty much just when i first apply the brakes. although i did just find out i cant re-register for another month cause the DMV screwed me again so well its off the road i might as well replace it all anyhow.

also just cause im curious, is it possible that since i replaced the line the pressure blew the wheel cylinder after i checked it?
