Rear Brake Lines

[teebes]

Splitting this out to a separate thread. With the longer rear control arms on, the rear brake lines seem to be doing ok, but are dangling from the former frame mounts.

I'm starting to look for longer lines, mainly for peace of mind. I found a local place that will make custom length braided steel lines, but they do need the originals first. I'm going to order up some replacement lines from a local auto parts store for the mock-up and to ensure they can find the necessary fittings.

So far, I've found the following details of our brake lines from AutoZone, of all places

Part Num:70857
Part: Driver side, rear
Brake Hose Assembly Length (In): 13
End 1 Fitting Material: Treated Steel
End 1 Type/Size of Fitting: Banjo - 10 mm
End 2 Fitting Material: Treated Steel
End 2 Type/Size of Fitting: Junction - (2) 1/2-20

End 1 Fitting Material: Treated Steel
End 1 Type/Size of Fitting: Banjo - 10 mm
End 2 Fitting Material: Treated Steel
End 2 Type/Size of Fitting: Female - 1/2-20

Sometimes simple things like this makes me miss the stuff we had in our shop when I was in the air force.

Why don't you just get an extended bracket to move them? A lot of lift company's supply them for certain lifts... which reminds me I've never checked my lines since I've lifted it and I've flexed my rear completely out.

I hope you can get this done, I thought there was something weird about the fitting, but I may be wrong. You are prolly right that you can use the safety margin when you head out in the desert.

I thought I remembered reading on the OS that the fittings are hard to come by/ different from other platforms... Hopefully it works out tho.

I ordered up a pair of stock replacements yesterday, I'll take these down to the shop and let them give 'em a once over. It will be a while though....

Just take the rear brake lines off... who needs em anyway. Just carry an anchor and throw it out the window when you need to stop.

There isn't one for us I'm sure, he's got Heep on the brain. But maybe he's onto something. It might be easier to extend the hard line, which has a standard fitting.

Good points...

One thing to note, on the drivers side rear, we have two steel lines merging at the end of the frame side of the brake line. Could still be done, will take some bending of the current lines though:

[SteveTB03]

Well you know how some brake lines are on a bracket or its attached to something on the frame or body that keeps it safe right? Well my lift I got from RC for my jeep has a drop down bracket that will move the brake lines down to accommodate for a lift but still keep it out of the way and safe.

Ill take pics when I get home of it.

Dropped off the OEM samples at the local shop. Asked for their stainless steel setup with a clear plastic coating. For length, I requested 5" longer than OEM. Their brake line guy was at lunch, so fingers crossed we get some good news by tomorrow.

[Zero]

This is great news! I hope they can make something for us. Broken brake lines are never good.

[Saxis]

Bah... brakes are for QUITTERS! When in doubt, power out!

Reverse + stall converter = adequate brakes.

Hey Greg... is it tomorrow yet???

here are some simple 1"extension brackets i made up.with some gentle coaxing you can make this work for an extra inch of play. if you need any more room you would have to get into either extending the rubber line or the metal line. still working on this idea so far so good.i put a nut(or a 1/4" spacer)
under the mounting location on the brake line to get the clearance so everything lays flush on the new bracket. kinda an idea.

Has anyone had issues of the rear brake lines (hand brake) being the limiting factor when installing Z71 rear springs? I went to install them this morning I noticed that after removing the rear shocks, putting the chassis on jack stands and lowering the rear axle (almost completely), the rear brake lines looked mighty tight. The Hanyes manual says nothing about the brake lines it only mentions to be aware of the trailing arms on the frame. My concern is that if the brake lines already look short, are they going to present a problem after installing the springs and a 3/4" spacer? Or should I just lower the axle partially and then use a coil compressor to remove the springs. The manual says nothing about needing a coil compressor to remove the rears, although I do have one. I just don't want to rip my brake lines off.

[Blackout]

The stock ones should come out pretty easily. Getting the Z71's and spacers in you need to love it a little. Instead of using a compressor for those (I was sick and tired of it after the fronts) I just GENTLY used a prybar and slight downward pressure on the axle to slip them in. Wasn't too difficult. If the brake lines are too tight, I'd compress the springs a bit.

Countless number of us are running the Z71 rear springs with spacers, I'm running the 2" BDS kit with the Z71 springs. The Z71 springs are the same height as the stock TB springs. There is a clamp that holds the brake lines toward the top of the assemblies, unbolt the clamp to alleviate some of the tension on the lines. You can use a pry bar to get the stock springs out, or the bottle jack to help push the axle down a little. I did 1 side at a time, others have done the whole axle.

[SteveTB03]

When I did the rear springs I just undid the lower sway bar mount and the lower shock mount and dropped the axle all the way until I could kick the springs off the axle then I literall kicked them back into the mount
