They're red the orange color is from the sun and my cheap camera. They are from Energy Suspension, the first link.

I've been sidelined for most of the last week waiting on parts. I ordered a set of SS brake lines for the front and rear, but I wanted some for the rear calipers as well. I found what I needed at Summit Racing. Earl's brand right length, right ends everything except they are out of stock til Dec. 1...then Dec 7...now Dec 12. I canceled the order and tried to figure out how to use the rubber lines I have. Most of the rear disc conversions I've seen online have either left the line dangling or welded the bracket to the housing. I wanted to do neither, so here is what I came up with. I reversed the lines from left to right and mounted them with the loop the bottom. I then ground the mounting tab to fit. Not what I wanted to do, but the loop is a good inch above the housing bottom and should work out OK...

The hard line installed. Still needs to be tweaked a little, but you get the idea...

Clearance shot. I shouldn't ever be an issue...

After drizzling rain all day Monday, today turned out pretty nice. I got inspired, so my son Jake and I yanked the old D35 out. A before shot...

Here's a couple shots of the factory 'load sensing valve'. I plan to bypass this and run a XJ proportioning valve until I upgrade to a dual diaphragm booster and newer model master cylinder. Then I'll switch it out for a ZJ 4 wheel disc unit.

No more D35, or much of anything else...

A forgotten part. The shackle bushings are shot, gonna have to order some tonight. Scrounged around a little and found an Energy Suspensions part number (2.2111G), be here in a few days.

Last stop for the old D35.

I hopefully will have all the parts together for the 8.25 install after I finish my 8 day stretch at work, that begins on Thanksgiving day.

Now if I can only make up my mind on a diff cover.

I was actually thinking about welding mounting tabs, but might try the way you did it.

I think the line should be ok, remember you'll still have the tire and wheel partially protecting that area.

My vote is for Riddler, those things are BEEFY!

Nothing wrong with zip ties. That fix crossed my mind a time or two, but as this project has evolved I'm unfortunately becoming more and more anal.

That is their 'Load Sensing Valve', from what I've read at it's best it worked poorly. I really don't understand the concept, definitely a MJ thing.

My first choice is the Riddler cover. I've just been looking for one I like better, no luck yet.

My educated guess would be as load increases, it would increase braking power?

In theory, I'd say you are correct, or maybe brake bias? Don't know. When we pulled it today I had my son press the pedal with the rear hose disconnected and the fluid just barely trickled out. When it was new it probably worked very well, now it's just scary.

**RockRodHooligan** · 11-24-2009, 09:43 PM

Yeah, it sounds like a novel idea, but too complicated compared to just putting better brakes on it, which is probably why you don't see it anymore, just big brakes lol.

Nice build so far! Oh yeah, get a Riddler diff cover.

Thanks, I'm ordering one Weds.

And why not a d44?? Isnt the 8.25 wider and less strong? You plan on wheeling this thing at all?

Actually many modern small pickup trucks and SUVs have that load sensing proportioning valve. The problem with the MJ's is that they have not been available since 1992 and the rebuild kits are long gone. 20 year old rubber parts just are not that reliable. It is much more simple to get a normal proportioning valve or use the factory MJ's 50/50 split with the load valve removed.

In theory, as the load increases in the bed more braking bias would be sent to the rear brakes. That IS the MJ's proportioning valve.

Nice work on the truck

The 44 is really only marginally stronger than the 8.25. Kind of like the 8.8 vs. Dana 44 argument.

Ok that helps, one day I do want an MJ as a DD/parts hauler/beat around truck, so now I know a little more about them. Though now that you explain it, it does make sense to do the proportioning valve like that, no point in having much braking power to the rear if there isn't any weight in the rear to keep the tires planted.

I'm not going to get drawn into some kind of diff debate on this, all the explanation needed for my choice of parts is outlined in my posts.
