brake line nightmare.. pics inside

[78Suburban]

Does anybody even know what part number this brake line is? Its for an IFS truck, and I thought it would fit mine.

Its for 10mm caliper bolts, so I decided to drill it to 7/16. I was going to get some new copper washers to go against the caliper and bolt. I'm afraid that I didn't drill the hole perfectly straight on one of the lines, as you can see in the pic. I also can't figure out which lines I'm supposed to use on which side, or even exactly how they're supposed to line up against the calipers.

THE REAL PROBLEM IS that the fittings on the end of these new extended brake lines are simply too thin. The caliper bolt bottoms out before it clamps the line down. So what do I do now? Stacking washers if asking for a leak. I thought about cutting a little off my hollow caliper bolt, but I'm starting to feel like my brake system is going to be very ghetto rigged... not a good thing!!!

Can I make these lines work? If not, what extended lines can I get for my '78 k20 corp 10, which has a 7/16 fitting??

somebody please help!!

For the ones I used, the napa part number is 38872. Here is a writeup I did on this:

I had to cut the banjo bolt on my Dana 44, but I think they will just work with the 10 bolt and dana 60. Regardless, they work great on my blazer.

I used 1984 Chevette lines on my rear disc conversion. They are about a foot long and cheap.

This is for front brakes, not rear

I'm thinking of grinding the hollow caliper bolt shorter, so that it will grab onto these thinner brake line fittings, is this a bad idea?

Do my holes I drilled look like they're straight enough that they'll even have a chance of sealing (I'm getting new copper washers tomorrow)?

As long as you dont cut off too much and clean the bolt, I dont see why you couldnt just cut some off. Building, not buying is the name of the game, and you can do it safely too.

1. Aslong as the copper washer covers your hole, which it will, you wont leak. Thats what seals it..

2. Take a grinder, cut off wheel, hacksaw, band saw, something to cut down the banjo bolt, but dont take a ton off.

Like I said, I cut mine off. Just like 3/8" or so with a hack saw. Then I ground the cut end to a taper and cleaned up the treads with a die. Works great.

If anybody else needs a short 7/16 bolt, this one is absoultely perfect!!!
