So my car has 2 brake lines going to the rear end and my 12 bolt rear end has a splitter built in with only provisions for only 1 brake line inlet. So how am I supposed to run my brake lines with the new rear end? I guess I could use the stock brake lines from the 10 bolt, but why the difference?

Also my 12 bolt is a 3-channel ABS-only rear end and the wires coming from on top of the pumpkin have been cut. What do I need to do? Can I just leave it, ABS harness disconnected? Do I need a new sensor/harness? If I leave it the way it is, will I still have front ABS?

 

Use the brake lines off of your 10 bolt.
To have ABS or TCS/ASR at all you'll need to get axle reluctor rings pressed on (if your axles will take them) and move your backing plates with sensors to the 12 bolt also.

 

I'd actually rather not have traction control, all it has done is embarrass me at the track when I forget to turn it off. And it looks like I'll be doing an ABS delete this week anyway.

So just use the stock brake lines? I'll see it I can get some kind of splitter to combine the two lines into one cause the brake lines are formed better to the 12 bolt and are bolted down differently than the 10 bolt, but as a last resort I can use the 10 bolt lines.

 

I installed a Moser 12. 3 channel ABS with the pick-up in top of diff case. I modified the stock 10 bolt brake line bracket to secure to the case gusset plate. Made a bracket with pinch bolts so I would not have to drill thru the diff case gusset. I also deleted the abs. I had to run an American size 1/4" brake line to the rear. The stock was metric and did not flair well (allways leaks). The brake ecm is gone now. Splice the light-green wire w/ 12 volt source for SES inst-light OFF. (97ss 383-D1 MM6) B.
