Something weird going on after lift install
 

I just installed a 3 inch teraflex lift and I took it out for a ride after getting it all together. I installed the extended brake lines and when driving it it feels as those at random times pressure is being applied to the brakes. What do you guys think this is? I bled the lines do you think there could still be air in them causing this problem?

If you had air in the line still your pedal would be soft and go to the floor. When you did the install did you over extend any of the lines or during reinstall did you pinch one of the lines? I would recheck those and see if you have anything obvious.

Check to make sure those hoses aren't twisted. I've seen people install calipers and have the line twisted when bolting the caliper back up. It could restricts the flow. Just double check

Your steering wheel isn't off center, and the ESP is applying the brakes is it? Do you feel it going around corners?

Did you re-center the steering wheel? Is there a lightning bolt icon blinking in the dashboard when you feel the brakes come on?

Steering wheel is off center. I don't see the light flashing but I will check and I it doesn't really matter if it's on a corner or straight

This may save you some time:

To center the wheel, change the length of the relay rod (some call it a drag link). Its runs across the Jeep parallel to the tie rod and has an adjusting clamp about 3" long with two bolts.

The tie rod has a knurled plastic adjusting collar. If you mess with the tie rod accidentally you'll need to set the toe-in also.
