I have a 1990 jeep cherokee. It has the 4.0 liter motor.
It has a 8in lift on 35" Mickey Thompson tires. Bought it with the disc brake swap of the rear. Was having trouble stopping.( soft pedal). The first thing done was to bleed the brakes. No improvement. The 2nd was to replace OEM brake booster and master cylinder. Bled the system no improvement in stopping. The next, I looked up was to do a swap to dual piston calipers. So I bought WJ knuckles Explorer sport trac rotors and dual piston calipers for a WJ. Changed the knuckles and now the rotors are same bolt pattern but studs are to big for rotors. I am stuck I need to know what to do. Do I drill out the rotors and hope it all goes back together. Do I look for what master cylinder would bolt on and be able to increase fluid volume to make jeep stop. Please help with answers
