Cherokee brake problem?
I have a 2000 jeep cherokee 4wd, with a rearend from a 97 grand cherokee. I had to change all four rotors calipers and master cylinder (lines all good and new flex lines) but i still dont have any pressure? Changed the master cylinder 2ce and bled all the brakes i dont know how many times. The front brakes stick but the rear dont. Any ideas?

Is there a proportioning valve on these things or is it in the master cyl? I know on other vehicles you have to install a disc/disc prop valve if switching from a disc/drum set up. Otherwise the rear will not get enough pressure. If it's in the master did you get a master for the donor or a stock replacement for yours?

Yes there is a proportioning valve. If you went from rear drums to disc you will need the one from a grand with rear disc. The internals can be swapped and it will do fine.

No the master cylinder is same. It would just need a proportioning valve. But make sure that the rear calipers are on correctly and not upside down.
I just did an entire brake swap and upgrade on my 1990 comanche. I went to rear disc and had to get the proper proportioning valve to get the correct amount of pressure to the rear.

I have a extra proportioning valve but I'm not too sure it will help. I'll give it to you, all I ask is you pay shipping. Less than $6 for a flat rate box from the post office or I can throw it in a envelope. Your choice.
