Rob1989 Posted June 5, 2017 Share Posted June 5, 2017 So today on my way to work I blew a house. Called AAA got towed home. As the guy is taking it off the bed we both noticed break fluid dripping from the rear axle. The hard break line going into the little square piece on the axle is were the link is coming from. Any idea were I could get a decent new line from or any other way to fix the issue? Link to comment Share on other sites More sharing options...
Eagle Posted June 5, 2017 Share Posted June 5, 2017 I'm confused. Did you blow the rubber flex hose from the rear chassis to the axle, or did you blow one of the hard lines from the block on the axle to the rear wheels? Link to comment Share on other sites More sharing options...
Gene Posted June 6, 2017 Share Posted June 6, 2017 Hi Rob, Not sure where you're located, but if your vehicle has seen road salt over the winters, you're probably in for a major job. All the rear lines may be rotted out. I'm guessing, from your description, that it is the hard metal line that broke, not the rubber hose. The rubber hose would be much simpler. There are numerous threads about rear brakes. There are two lines that come from front to back, one being the main braking line, the other being an emergency circuit to give full pressure to the back if you lose front brakes. There is also a height sensing valve connected to the rear axle, to help to adjust the amount of force the back brakes have. In my case, Western Pennsylvania/Western Maryland winters, about every seven years I would have to totally redo the rear brake lines. These are not available premade, you have to either piece together preformed sections (if I recall, 5 foot +5 foot +1 foot will reach the rear axle) or buy a 25 foot coil and a double flare tool, and make up your own lines. http://comancheclub.com/topic/38551-rear-brakes-main-hardline-broken-above-gas-tank/?hl=rear+brake+lines&do=findComment&comment=477933 http://comancheclub.com/topic/33072-rear-brake-lines/?hl=rear+brake+lines This would also be the time to replace the rear rubber hose, as well as wheel cylinders. Bleeding rear brakes is a subject unto itself, there are numerous threads about this, it's complicated and time-consuming. http://comancheclub.com/topic/52319-proper-brake-bleeding-procedure/?hl=brake+bleeding Finally, there are threads about simplifying the rear system. http://comancheclub.com/topic/51268-load-height-sensing-valve-delete-bypass/?hl=rear+brake+lines&do=findComment&comment=522799 Good luck!

SBpunk Posted June 7, 2017 Share Posted June 7, 2017 The hard line is really easy. Even if you're not comfortable flaring the hard lines you can buy the "easy" flex line (think that's what its called) from NAPA. If you ask they'll flare it right there. Just bring in the old line. For the rubber line look into getting an extended one from a chevy (google it on naxja for the exact years) it will give you some play room and bolts right in.

Gene Posted June 7, 2017 Share Posted June 7, 2017 The hard line is really easy. I hope that's the case! Every time I had to touch the rear brake lines, I had to replace everything, from the proportioning valve (under the master cylinder) back to the axle, and the lines over to each wheel cylinder. At least in our neck of the woods, the long lines, especially where they pass between the frame and the gas tank, are what rust first and worst. If this should be just one isolated line, and there's not much rust on the nuts or fittings, agreed it would be much much easier. Bleeding is still a bear!

SBpunk Posted June 7, 2017 Share Posted June 7, 2017 Check out Motive Products power bleeder number 0105. Best 60 bucks I've ever spent. I use attachments for different vehicles but I never have to worry about my brake system. You can check to make sure it has a good seal (no leaks) and you'll be able to bleed all 4 brakes including your height sensing valve by yourself. I deleted mine awhile back and its been great but some people like them. Link to comment Share on other sites More sharing options...
SBpunk Posted June 7, 2017 Share Posted June 7, 2017 Correction 0103. The other one was for my grand wagoneer. https://www.motiveproducts.com/collections/domestic-bleeder-kits/products/chrysler-dodge-mopar-bleeder Link to comment Share on other sites More sharing options...
Gene Posted June 7, 2017 Share Posted June 7, 2017 Hi SBpunk, Thanks for the link. I had been looking at one of these for a reasonable price, anything that I had found had been about three times this much. That certainly will make bleeding easier.

Gene Thanks for the tip I put in my I've got to have that file. Upgrading to the 96 Grand booster soon so I could use it. Have 3 cars that could use a change in fluid and I live alone, awesome.

HOrnbrod Posted June 7, 2017 Share Posted June 7, 2017 I just bought one from Amazon for $42 shipped. It doesn't have the correct master cylinder adapter, but I have plenty of spare caps and hose barb fittings, so I'll make my own. I've been meaning to get one of these for awhile now; thanks for ringing my bell. :cheers: Link to comment Share on other sites More sharing options...

I had been looking at one of these for a reasonable price, anything that I had found had been about three times this much. That certainly will make bleeding easier. Gene Anytime. I upgraded to 96 XJ booster/MC, deleted my rear load valve and have 8.8 w/ disks in the back. Thing will put you into the windshield if you're not careful. YJ lines up front and chevy in the back (soft lines) so plenty of room for my little 3 inches of lift. Overbuilt hahaha. Eventually I want to get some Black Magic pads. Worth the money but for now the brakes work great on my tire size and soooo much more left to do. Good luck and let us know if you run into any problems. Hornbrod and Eagle have pretty much rebuilt my jeep via forums so awesome resources if you need it. Link to comment Share on other sites More sharing options...
54bobby Posted June 10, 2017 Share Posted June 10, 2017 i'm the op's pop. the line that blew is the one that runs from the small metal block on the drivers side rear axle across the pumpkin and into the passenger rear wheel cylinder. what is the size of this line?

Jeep Driver Posted June 10, 2017 Share Posted June 10, 2017 I make my own, doubt you'll find a ready-made part. I'd remove the line, carefully as to not distort it's shape, take it to NAPA or a good hydraulic shop and have them make you up one. 3/16...........IIRC..........one end will be flared already, they/you will have to bend to shape and cut and flare the remaining end.

Hi 54bobby, Be ready to replace more than just this line. When I had to relpace "A" rear line it turned into replacing "all" rear lines. Hope that is not the case for you! There is another thread going about brake lines you may want to take a look at that. Nevermind, you started that thread! Good luck! Gene Link to comment Share on other sites More sharing options...
