SOURCE: Brake line hose has hole in it
The only real solution to your problem is to replace the damaged line, bleed the brakes, and check for leaks after you are done. The line should go up to the frame, and go into a small metal bracket that is welded to the frame. The hose is usually held in place by a small metal clip, and a steel brake line will thread into the end of the hose assy. where it terminates in the frame mounted brakcet.

The proportioning valve most definately can be the problem. Did you change it or is it the original? (A disc/drum system uses a 70%front/30%rear braking ratio, whereas an all-disc system is alot more even). I would first bleed the master cylinder. Then I would 'gravity bleed' the rest of the system by opening the bleeders on all 4 wheels. Do not at any point let the m/cylinder go dry. Also, do not touch the brake pedal.
Continuously check all 4 bleeders, when clean brake fluid with no bubbles at all is running from a bleeder, close it. When all 4 wheels are done, recheck the fluid level and you should be OK.
Pump the pedal to 'self-adjust' the rear calipers, then re-check the fluid level.
Any problem after that means you either have a loose connection (it's possible for a tiny leak to let air in, but not let fluid leak), a leak, or you need a new (disc/disc type) proportioning valve. I would try Summit Racing myself. Good Luck!

You say they replaced basicly everything that involes the rear brakes.
Every step they took to find the problem could lead to the solution,BUT did they check the inboard brakes. The brake system on a jeep that has rear rotors have inboard shoes for the parking brake.
You could have a parking brake cable that is frozen (this will cause a drag on the inboard brakes. Do you use the parking brake? Maybe the parking brake shoes are adjusted too tight?

SOURCE: rear brake light are not working
The CLK HAZ STOP 20 Amp Fuse protects the Stop and Hazard Flasher circuits and is located in the fuse panel under the left side of the instrument panel.
Even if you can't find it, try your Hazard lights to check it. If fuse is OK, check Brake Switch on top of the brake pedal. It is a Normally Open switch, check for power coming in, if OK, disconnect electric terminal and check it for continuity, if none, replace.
