I got a 2010 jeep jku and I got 2022 jt brake calipers and rotors for free that only had 10,000 miles on them so put them on the jku fits good but bled the brakes an don’t have a good brake pedal anyone know if the booster and master cylinder out of a jt would fix it or know of a good booster an master cylinder to buy thanks

 

Need to upgrade the master cylinder. You can buy the J8 master cylinder and booster to make it work. The whole kit has been on back order for awhile but you can buy the parts individually from Mopar.
