Attention 89-92 Rear Disc Owners...help Please

Ok, this may be someplace on this board, but I have searched until I went cross-eyed. Does anyone have a picture of how and where the 89-92 PBR e-brake cables run? Specifically, how the brackets mount in the drive shaft tunnel. I have all of the parts, but I can't for the life of me remember how, or where, those brackets mount (it's been a while since I pulled them out of the car). If somebody has a picture of the tunnel that shows where they mount, please post it here or e-mail it to me. I played with them for over an hour and couldn't figure it out. Thanks in advance!

JamesC has some real nice pics of his rear brake brake install, maybe you can pull up the thread he started on it. I also have pics in one of my albums, click the link in my sig and go thru it. Other than that, they come off the brackets on the caliper, run over the axle with one on each side of the driveshaft, and into the adjuster bracket. You'll also need to use those little "S" shaped hooks to keep the cables off the exhaust or you'll burn one on it. Take a look at my rearend install album, that should do it.

After looking through the pics in that album I have just one more question. Did you just use the brackets that were in your car? I got all of the parts out of a parts car, including a bracket on each side from above the driveshaft. It seemed to me that the brake cable was way too long to use the brackets in my car. I'll give it a "re-look" tonight and see if maybe I had a little case of rectal cranial inversion. Thanks ed, you are the brake king. On a side note, I can't find the post about the C4 HD 13" rotors, are they fronts or rears that you use up front? I've had a guy ask and I can't remember for the life of me.

Yes I did. The only thing I changed on the car during the rearend install was the rear (went from '88 9 bolt to a '89 9 bolt), used the correct PBR brake cables, and swapped to the 1LE prop valve. It bolted right up. The cables will have just a bit of free length to them, they shouldn't be tight so to speak. But when installed in the brackets, you should have enough length to make it to the adjuster bracket above the driveshaft.

13" C4 HDs use the front HD rotors, the 12" C4s use the rear rotors as I do them.

I have them in place and the sheath is fine, it just seems that the cable itself is way too long, but like i said, I might just have had my head up my ***. I will be looking at it tonight when I get home so that hopefully I can drive it this weekend.

I did have to adjust mine a bit. I had to move the adjuster bar up towards the front of the car to take up a little slack in the cables. My car is an '88 so the bar can move with the adjusting nut. It's my understanding that '91-92 cars have no adjustment in this area like the earlier cars do.

Well I got it figured out last night. I tried like hell to get them to work in the stock 87 locations, but it just set them about an inch too far forward, the adjuster ran out of threads, and the cables were still about an inch from snug. It also put them in a bit of a bind, especially on the passenger side. I took another look and low and behold, I cracked the code. Those other brackets I was stumped by, bolted into the 87 retainers and pushed the point at which the cables anchor to the car rearward about 2 or 2.5 inches. Once I figured that out, yahtzee, the cables layed right in place. It also routed the cables over the diff without binding them. Anyway, thanks for the help Ed, I really appreciate it.
