Brake line routing guidance
 

I'm trying to install an In-line disc brake conversion kit in my 64 c10. The old lines I took out we're a total mess and are no help for a pattern. I think have have the lines that run behind the cross member to the passenger side front brake and along the frame rail to the rear brakes somewhat close, but I can't figure out how the lines that run up to the proportions valve go??? Can someone that has ran their lines lately point me in the right direction? I just have the lines kinda zip tied together until I know I have the routing somewhat close.

Ahhh the memories of cussing and frustration. Looks good so far. The 3rd pic should have both coiled lines running to the prop valve. hard to tell they way the pic was taken if the forward one is a coiled one also. I used andale clamps ( rubber padded metal strap clamps) and ran a bolt/nut through holes in the frame to secure my lines. The zip tie trick you are using worked well for me also to hold them at one end and position them so they didn't swing around.

If you ordered the lines from CPP, They will email you a line drawing as to how they should be laid out. That helped me a lot.

Here is the line drawing from CPP. This is how I did mine. Hopes this helps

I found this pic I saved a while back. Hope it helps.

Not to highjack but I was wondering if you switched the u bolts on the bottom control arms to the 3/4 ton ones? If you havent you might give it a thought since you can get at them easy right now.

Re: Brake line routing guidance
 

Thanks for the pictures and the drawing; now I know I'm heading in the right direction. As for the U-bolts for the lower control arms, they were upgraded to the larger size.

Here we are a decade later and I'm still running into the same issues with the same brake line kit... glad I checked here before I lost my cool and chucked that line in the creek! LoL

Re: Brake line routing guidance
 

At the beginning of this video, I show how I ran mine. Still not completely finished, but I had to do some sitting and thinking too. Mine are pretty much like the ones above.

Hey Bob what kit is that in the picture?

Re: Brake line routing guidance
 

Hey thanx for the link, after talking further with CPP and reviewing some of their photos they sent me, I finally figured out that they straighten the tubing bends to reduce the size of the box they need. Once I figured that out, I'm hoping to get it installed without further issue!

Beautiful chassis btw!

Re: Brake line routing guidance
 

Thanks,
I am sure I will be doing some bending to mine too.

Re: Brake line routing guidance
 

Has anyone run into an issue with the CPP kit regarding the rubber lines rubbing against the caliper / spindle? I cannot seem to figure out a routing that doesn't rub. I just now ran across a photo on the internet where someone put a loop in the rubber line... not sure how that would work long term, but it didn't look like it rubs.

Re: Brake line routing guidance
 

Mine are long too. I ask the same question and others suggested the loop. When I tight everything down on my suspension and finish the brake lines, plan to try the loop too. Someone also commented they found shorter hoses for a different year, but I can't remember if they included a part number.

Re: Brake line routing guidance
 

Does anyone know where to get the 90 degree brake line fittings like in this image from earlier post in this thread?

I looked everywhere for them when i was redoing my front lines and people at the parts stores looked at me cross eyed when i asked. They all only had the tee fittings with 3 attachment points.

Re: Brake line routing guidance
 

I imagine Inline tube would carry them. I found some fittings I needed on amazon as well.
I was able to bend the line off the frame to match the line coming across the crossmember, and used a straight connection (not sure if your application would allow this).

Re: Brake line routing guidance
 

Yeah thats what i ended up doing just bending the lines but i plan to redo all the lines soon so my OCD would appreciate the 90 degree connections LOL

Re: Brake line routing guidance
 

Aren't those 90's available in hardware stores plumbing sections? I remember making metal pipes (brass = led = we were idiots) when I was in high school decades ago and using a 90 degree like that from an Ace Hardware store.

Re: Brake line routing guidance
 

I've put 21k on mine so far with looped hoses, no rubbing and they're holding up no problem.

Re: Brake line routing guidance
 

In regard to the rubber lines rubbing, I did phone CPP and ask the question.

They noticed in my photos that my suspension was still at full droop (jackstands under the frame) and said that when I put the vehicle under load, the suspension geometry moves the spindles outward as well as upward and that should solve the issue I was seeing.

I placed the jackstands under the control arms and sure enough, it was not rubbing, except a very slightly during full lock turning. I'll continue to keep an eye on it once its back on the road, and maybe have some hoses made custom?

Found this on Napa Online not sure about size for your application. Says they come in brass, Stainless steel, or carbon
