Rear dual brake hoses

[donjetman]

Today I installed new dual rear brake hose setup Genuine GM# 176-1525 - $63 amazon.
Gravity bled the brakes afterwards.

Preventive maintenance or were they leaking?

Very nice. I think most people overlook those two brake lines.

preventative.
I changed the other 4 hoses when I did the front & rear brake jobs.

Good write up & pic. I never would of known about those little suckers unless I saw it pic & part #

The 14-bolt axle has a different part number but I misplaced mine and kept the original lines when we put the 14-bolt in. No issues, not sure what the differences are.

I’m spitballing it but prolly the bracket or length of hose.

Same bracket, I'm figuring hose length but not sure if longer or shorter. Next time we do rear brakes I'll change it out unless circumstances demand sooner. Last set went 85K miles.

@donjetman, if I may ask, what tools did you use to crack the hardlines loose from the upper ends of the hoses? I have that new hose assembly for my 2013 Escalade. However, when I was laying on my back under it, I could not get my fat hands and any kind of flare wrenches up there to crack the hardlines loose.
I will gladly take any advice you have for doing this job.

Thanks!

There is the set called JOUNCE from GM . Then the aftermarket just shows
individual center lines... IDK what the diff is.
The indiv lines are diff lengths (longer) for the 9.5 rear end.

You might want to tag @donjetman like this if you want to be sure he gets a notice that he's been mentioned...

Here's what I used:

My vehicle doesn't have any corrosion, that helps.
And I have a lift.

Move any/all evap lines out of the way.
Have the master cyl full and leave the cap on.
Leave the 2 L brackets attached to their mounting points until you have the 4 fittings broke free. Don't totally undo them (4) yet, just crack them (4) free to minimize fluid loss.
Work quickly so as to minimize brake fluid loss from the master cyl. When I started the job fluid was at the MAX line, and when I finished it was at the ADD line. This makes bleeding the brakes easy.
I removed the bottom 2 first, attached the new 2, set the other loose end up on top of the cross member to minimize fluid loss (gravity), while undoing the top 2 fittings.
Remvove the ole hose assembly and a connect the top 2 lines.
Reattach the new assembly L brackets.
Refill master cyl.
Gravity bleed brakes. I did all 4 calipers starting at the furthest from the master cyl.

If you let that master cyl run dry/get air in it you will need a tech2 type 2way scan tool to bleed the brakes. I don't own such a device.

Excellent! Thank you very much for the advice.
I have a pressure bleeder and a Tech 2.
I don't have a lift. But I know someone who does...

Appreciate it!

I forgot
"REMOVE THE SPARE TIRE" first.

I'm good. My Escalade has the twin exhaust tips through the rear bumper cover. No spare tire.

@donjetman !!!!!!
I’ve been looking for these racking fracking brake hoses for 6 months! You’re doing God’s work, my friend! Thanks for posting!
