No Rear Brakes! -- 2000 Jeep Cherokee Sport?
~70,000 miles; Auto Trans; 4wd; no leaks
Started off getting new pads and shoes (front disc, rear drum). Found that there were no rear brakes (noticed on wet pavement and tested on gravel) but likely preexisting. Multiple visits to independent shop, got the following new parts: 4 brake cylinders + hoses, rear brake kit, master cylinder, proportioning valve.
No improvement. The shop had no idea, so I took it to a registered Jeep dealership. They spent 6+ hours and all they found was that the rear drums were cut too thin: replaced both. No improvement. All they could suggest was replacing everything again.
The original shop started over with genuine mopar.
Emergency brake functions properly. The peddle is firm - lines bled multiple times with "good output". The system has been replaced in full twice, but still no rear brakes. The peddle is a bit higher than before work began, but the problem may have existed before this work. No squeaks/noises.
I NEED HELP! Thanks

You know what is weird about your situation, I own a Jeep Liberty Sport 4x4 and have had brake issues with it for over 2 years now!! When i took it in to LesSwabb to get my brakes done again this summer, the guy said it's a common problem in newer jeeps

Ok, do you work in the jeep yourself? If so, can you YOURSELF try to bleed the brakes? IF fluid comes out of the bleeders while someone else is PUSHING the brakes and the pedal goes to the floor, the above parts are working.
Let me ask this, how do you KNOW the rear brakes are not working. They will have less stopping power than the front due to ABS and the proportioning valve and that is normal.
With the rear end up and supported by jacks, MAKE SURE YOUR ARE IN TWO WHEEL DRIVE!!!! Start the engine with the brakes on and put into gear. Do not accelerate for safety, Can you hold the rear tires from turning? Let go of the brakes and then can you stop the tires from spinning with pedal application?
One last point, but a stretch, have seen the INSIDE of brake lines rust closed, but if you can bleed, this should not be the case.
If the above proves you have brakes, and have ABS, reask how to improve the rear brakes in an ABS Cherokee and I can help there too. YOU MUST HAVE ABS.
Good Luck

I believe your problem is in the proportioning valve. Get an adjustable proportioning valve similar to what they use on drag racing cars. Then you can set it to the amount of rear brake bias you want.
