So i have read one or two post where people have called the jks brakes mediocre and in sufficient. Well i will say that after having a deer jump out in front of me today, they are very good lol. Granted i only have 32's i have the heaviest 32 known to man aka trail grapplers. I hit em hard and felt all the blood swoosh to the front of my face. Just wanted to have a positive post.
