Brake hose help!

[ghalperin]

I'm putting ECE drop spindles and Delco calipers on my 67 C10 frame. I would like to find the correct hoses for the front. I purchased 71 hoses, but they appear to be too long. Does anybody know what I should get and where? How long should they be?

Something does not look correct.

I think your cross member is on incorrect. Need to swap it around 180 degrees. The hose mounting bracket on the cross member should be towards the front of the vehicle.

See picture of my setup for a 1972 drivers side.

Its a drum brake truck getting discs on for the first time I would imagine. Hose brackets aren't in the same place I do not think.

Thanks, but the cross member only goes one way. My C10 is an early 67, built on 9/15/1966. That's where the lines mount and I'm not changing the line routing.

Drum brake trucks mounted the hoses and lines on the rear side of the crossmember.

When GM went to disc brakes in 71 the entire layout changed and the lines and hoses go to the front of the crossmember.

There is absolutely no way the crossmember is backwards.

The easy button is calling ECE and telling them you need a pair of front brake hoses for converting a drum truck to discs. They sell special conversion hoses for this exact scenario.

Glenn,
I'm finding the same issue as you are. I purchased a complete front crossmember and really dropped the ball!! I didn't ask the guy what year truck this crossmember came off of! I ASSumed they were all the same!
My truck is a 1972 and the brake hose connection is on the front side of the crossmember, and the one I bought is on the back side. (I kept the old one for reference)
The hoses came with the assembly but weren't connected to anything when I picked it up. Only when I went clear through the assembly and attempted to connect the lines did I see the difference.
I haven't made the change yet, but the plan is to cut the existing brackets off of each crossmember, and bolt the ones off my original crossmember to my new one.
The plan is to do this swap this weekend... I'll check back and see what you came up with for a workaround and hopefully have pictures to share.

I just did a disc brake conversion on my 68. The brake hoses you need are part number 88466 at autozone. $9.95 each, they are the same ones ece sells for $50 a pair. They connect directly to your existing brake lines and your new calipers with no adapters needed.

Sweet! My local Autozone has them in stock. I just ordered them and will pick them up in the morning.

Now can you help me with the proportioning valve and the rear hose to connect the 71 rear end?

Thanks for the suggestion, but I already called ECE. All they had was some generic 16 inch hoses. They recommended that I had custom hoses made up. My local hose shop will make braided stainless for $35 each, but its up to me to tell them how long they need to be. I'll start with the $10 Autozone hoses and go from there.

That's a change for them. They absolutely used to sell them. But, Zepp is right, they were 50 bucks per pair ten years ago. It sounds like the Autozon route is a big savings.

You need an inverted flare adapter to connect the brake line to the valve at the rear. I searched every fastener store around and NONE had the correct one. I purchased a set of three that cpp sells and the 9/16-18 was the one I needed. Here is a pic of the adapter on my truck. I also had to bend the oem hard line but that was easy to do even by hand.

[leddzepp]

This is the adapter pack I purchased.

Front brake hoses as mentioned above, sorry pics are sideways.

I see that you have the hose going up from the caliper. Was that necessary for tire clearance?

I picked up the hoses from Autozone.



Thanks for the tip on the adapters.
I'll Run up to CPP today to get them. Where did you get the proportioning valve?

I have this brass one.

Does anybody know what brake hose I need to install my 72 rearend in my 67 frame? The stock hoses are way too short.

Is the 72 hose longer ? I've done that swap a pile of times but I can't remember what hose I always used. Whatever it was it was simple and never a holdup, so I probably used the 71-72 hose or 73-87 hose.

Thanks. The 67 and 72 hoses look to be about a foot too short. I'll order the 73-87 hose.

Although, my neighbor has a 75 K10 and his hose looks pretty short for my needs as well.

After some filing on the bracket, I was able to get the hose flange to fit.

[midniteblues]

I did the kids 67 the same way your doing it.

Then when I started mine I figured I would eliminate the small issuses and just use a complete 71-2 c member.

Glad I did as everything fit together so much easier and I dodnt have too figure out which parts fit what.

I save every fitting I can off anything as long as it's still useable.
Oe fittings are much better quality than replacement ones and they clean up easy and fit new lines perfect if you can flare them.
There is a few odd ball fittings, that one in the back of the valve can be one of them.

I also save all the fittings, I should have sent them to get zinc plated. I'll send them next time.

Yesterday, I took my proportioning valve and brake line to the local Hose Man and they ordered the correct adapter fittings for me. I'll get them on Tuesday. I was going to get them at CPP yesterday, but they close at noon and I wasn't ready.

I ordered the complete set of hardlines from Inline tube as well as the three flexible lines.
I'm having trouble getting the manifold on the rear brake line to connect to the hardline! They aren't the same size!
I'm also finding that the banjo bolt for the front won't thread into the rotor...

I made a huge mistake thinking that the front crossmembers were all the same. I bought one that was rebuilt already and failed to ask the young man what year truck it was off of***
I've noticed that the mounting tab for the connection between the hard line and hose is on the opposite side of the one on my 72, so I'm pretty sure it's not off of a 72!
I'm going to have to call Inline tube and see if I can figure out what I have because I can't get ahold of the guy I bought the parts from...
If anybody reading this knows him or how to contact him that would be greatly appreciated.

His name is Andres Ham, he lived in Spring Texas when I bought the assembly.

Otherwise anything that would help with identifying what I have would be appreciated as well!

Can someone post pictures of the way this manifold block over the differential is mounted please!
What I took off was a stud style bolt that was one of the differential cover bolts. The new block I bought has a much larger hole through it, and it doesn't look like it's close enough to mount in the original location.
