I've done more than a few searches, and haven't found an answer to my problem.
Here's the summary.
90 XJ, brakes were fine until axles were swapped. Swapped in a non disconnect HP D-30 of the pre-90 era, just like the axle it replaced. Disks and calipers went right on. Also swapped in a D-44. After bleeding, the brakes would lock if really stomped on, but barely.
I got it home and bled it some more, but really didn't get more peddle. I put on new drums, and new cylinders in the D-44 so every brake part was new. Better but still not enough pedal. Fixed the YJ e-brake cables so they would work, and adjusted the e-brake to 4 clicks, better but still not enough pedal. Replaced a caliper that had the bleeder screw broken off, and put speed bleeders on all four corners. The caliper was used and had been sitting around, but it was full of fluid. Bled some more, still not enough pedal. Replaced the brake booster. Nada. Replaced the master cylinder, better but still not right. I've bled close to 3 quarts of fluid through the system.
Today, I tried replacing the front brake pads at the suggestion of my neighborhood mechanic. No better, actually seems worse. I'm thinking that the used caliper I put on isn't working as well as the other caliper, but it does work, it holds the wheel when the brakes are pushed. All of the flex brake lines are braided stainless steel, nothing is leaking significantly that I can see, brake fluid does not decrease noticably when I use it, but I don't really drive it much. It stops, but not as quick as it should.
Don't bother bemoaning the poor brake system in the XJ, mine when it was working right would lock up all four wheels without trying real hard. It should work just fine for 31's.
I'll probably replace the one caliper, but I can't see how that would magically make the peddle correct.
I'm open for suggestions. I'd like to get the brake stuff over with so I can move on to all the other crap I need to get done for Colorado Fest. It would be nice to actually try out the NP 241J and the TeraLockers and the MTR's on a trail. :laugh3:
