When I had the lift installed, I also upgraded to Rock Krawler stainless brake lines front and rear. Under moderate braking [harder then normal but not emergency], it seems the Jeep pulls to the right a little. It's controllable, butt noticeable. I checked the tire pressure, and all the tires are right around 32psi or so.

Any ideas?

 

Maybe some air still trapped in your right front line? I'd try bleeding them again.

 

X2. Bleed the oposite side from your pull. If the front left is what's pulling then re-bleed the front right.

 

I was having the same issue.
Bled them well after the installing 6" longer lines and 3 weeks later bled them again after it was pulling during braking. Found air bubbles in the left line only. Seems ok now.

 

it doesn't show in your profile what lift you have, but also check your track bars to be sure the axles are centered on the jeep. a slight difference can also cause pulling.
