Don't waste your $$$ trying to fix anything ... nothing is broken. This is a pi$$ poor design and the only way to potentially improve the situation is to install an adjustable proportioning valve. The problem with doing this is there just may be a reason why Jeep designed the rear brakes to suck.
I would not expect replacing parts with the same parts would do anything unless one was originally bad . The Discs on mine came from something else and I bet to improve it safely will require parts for a vehicle other than a TJ . Adjustable proportioning valve mounts inline to the rear brake line only giving you the option of reducing the effects of the rear brakes which don't help unless you can provide a need to reduce it , unless I misread it and I think I have read they are not legal on a vehicle that goes through state inspection in NJ anyway . Sorry I am still not convinced their is not a way to improve it . Seeing how the brakes are tested at the NJ inspection station I would guess that if they can't be improved on I need to put drum brakes on the 8.8 by October
