Did I run my disc brake lines wrong?

'75 D44 chevy front disc brake conversion

Should I have run the banjo bolt toward the front of the vehicle and wrapped my flexible line like in this tech article:

Or are my flexible lines just too long and I should just swap with shorter ones that won't rub the tire?

I've got mine pointing straight up and looping over to the hard line.

They look too long to me. Can you run them any differently?

 

[techlaf]

I thought that notch in the caliper "told" me where to run/orient the line. Is there any problem with running the line with a loop and the banjo bolt line oriented straight up like Justino suggested?

mine are a little shorter, maybe if you flip the caliper end of the line,it may direct the line away from the wheel or just replace with shorter lines.

you need to reroute. I can see where the line has been rubbing the tire, that is not good.

Personally I would rotate the banjo so the line points back toward the ball joint. That keeps it away from the tire and since it is pointing toward the pivot point it only has to bend to match the steering angle instead of needing to accordian with the travel. Be sure to check for clearance through out the entire steering arc, not just straight ahead.

It does, but for the original application. As long as there are no bosses or ridges that get in the way, there really isn't any reason not to re-orient it if it can help.
It's probably a safety thing, when used in it's original form, to keep the hose from spinning the bolt loose, but a rubbed-through hose sure won't care if the bolt is tight or not!

I'd agree though, that your hoses are longer than needed. Can you play with it a bit to see if a shorter one will work and won't leave you with some other kind of headache?
If so, I think that would end up being your best route.

Your banjo bolt looks different than what I used...not saying mine is right or yours is wrong. My lines are pointing straight up though. My bolt/box end has two wings on them, and the wing sits down in the notch on the caliper which holds mine in place and points the line up. Think of it as an upside down "T" and one of the wings fits in the notch. I bought my lines from JBG.

 

[DirtDonk]

Good catch Cortez. I'd completely forgotten about the wing/tab. On the last one i worked on the stock-type GM rubber lines terminated in a block that had that additional wing(s) to line up in that slot.

I like braided, but if you ever have trouble with the bolts loosening up over time techlaf, maybe go back to a stock-type hose with the factory end on it.
You probably won't have a problem, but just in case...

it appears like the flex line is about twice the length it needs to be. I figure it should be just long enough to start to go "tight" with full lock in whatever direction that is. Looking at the chevy tech page, it looks like if a 45 deg banjo fitting was used on the caliper (pointing to the frame fitting), that would setup the line to be flexed better both full lock left and right and keep it off the tire.

 

[techlaf]

Do you have a good source for the 45 deg banjo fitting or braided SS lines in shorter lengths?

My lines have been rubbing the tires and burnt the vinyl coating off of them. They're probably fine, but I'd feel better changing them.

if you smoked the line you probably burned the brake fluid as well,,,
