Thanks for the help getting this 98 XJ 4.0 back up and running! I posted that the ground connection on the block, just by the ignition coil, wreaks havoc on everything from the gauge cluster to the transmission. Cleaned all those up and it runs like a top. However, I have a ruptured metal brake line just below the master cylinder at a bend (it's the one that goes to the right rear brake). I've seen a cool option at rockauto.com https://www.rockauto.com/en/moreinfo...hwTWD4lee50VpE
It looks like a pretty straight forward replacement. Before pulling the trigger on this, I was wondering if anyone has any better ideas?

I know it's been stated before in other threads, but those grounds on the block by the ignition coil are....critical.

 

Looks like a good kit . just be care full bending the lines

 

There is only one main line off the proportioning valve going to the back going to the back brakes.
Goes to a rubber hose and that "junction box" on the rear diff.
Then out to both rear brakes from there.
At least in my '00.
Oh and without ABS which I know nothing about how that is set up.
So I am wondering exactly which line you are talking about.

 

Thanks guys. I got four lines coming off the master cylinder, and they're all metal to the wheels. It's a 98 (early 98, built in 97), no ABS. I should get the brake line kit I ordered Wednesday and see how it works out. Ad says a "tube bender recommended" and I have one. Once I got everything running, I was going to bleed the brakes after replacing the brake fluid. I sucked out the old brake fluid with a turkey baster, put in new fluid, and started to pump the brakes when I could see mist coming out the engine compartment. It was brake fluid! One of the metal lines failed at a bend just under the master cylinder. Hopefully it does the job and gets me back to a daily driver (I didn't drive it for a while because I was doing home inspections and my vehicle for that is....don't laugh...or laugh if you want...an '02 F-150 with the 4.2 V6, 5 speed manual transmission, manual windows, and manual locks that was a grandma purchase with only 65k miles).
My XJ has only 235k miles on it, and the motor and transmission are still strong as a mule. I put new brakes on it all around a year ago, and when I was in Italy with it ordered all new major suspension components from rockauto and had them installed. It's been driven through from Texas to Rhode Island, Chicago, Jacksonville FL, Italy, France, Spain, Croatia, Slovakia, Germany, and some other weird places. I bought it new off the lot in Bastrop, TX in January 1998 so I just can't let it go.

 

I am working on my jeeps brake lines currently. That would be the line that runs from the master cylinder to the rear axle. If it is broken you have no rear brakes. My suggestion is if one line went the others aren't far behind. In my opinion it might be better to replace all the lines and hoses. That's what I'm doing. There is a kit on rockauto from dorman that had all the lines pre bent.

 

All metal to the wheels! I doubt that. If you have a suspension, steering, there has to be flex in the lines. There should be hose at each wheel or to the axle.
