2000 xj. 5 inch lift. 4.10 gears. 33 inch tires. Overall poor braking performance. I did the rear grand cherokee disc brake conversation.the Jeep had poor braking when I got it. I've tested the booster per service manual. It is fine as with the master. I did the proportioning valve inner parts swap.im using the same type of pad and rotor material that I had on my 87. My 87 had napa rotors/pads and 95/96 XJ master and booster had fantastic braking.i went into the jeep parts catalog (i work for a dealership and have that access) and found the master is the same on an XJ with drum and a ZJ with disc.
