Front Brakes 67 disc

Can someone answer something for me? I took a look at the front brakes I have (I didn't put them on) and I have a hydraulic hose from the caliper (single) to the steel lines going to the proportioning valve. Are there supposed to be caliper lines in addition to the hydraulic hose on each side? Kinda need to know in a hurry as I am going to NPD shortly and would like to go only once this weekend.

Each front caliper has its own hard line and its own flexible rubber hose. The hard lines go from the distribution block under the master cylinder to a frame mounted bracket at each front wheel. The flexible rubber line goes from the ends of these hard lines to the calipers. I hope that answers your question.

A single, larger hard line goes from the distribution block to the rear axle. This line runs underneath the car on the driver's side.
I'm not sure. I found caliper lines that are short and look to be braided (ricks) as well as the hydraulic hoses. not sure if I need one or the other or both.
OK - I think I figured out your question. Assuming the steel lines (hard lines) are in place, you need flexible lines to hook them to the calipers. The factory used black rubber hoses. The braided lines you are talking about are an "upgrade" that would be used instead of the black rubber hoses. Unless you are building a show car, stick to the black rubber hoses.
MB's post reads she may have 69 calipers (single piston) on the front rather than 67 (four piston). The car could also be a changeover from drum brakes.

A good check is the hard line at the frame where the rubber hose attaches. Disc brakes have the hard line ending on top of the frame rail where drum brakes have the hard line going over the edge and pointing down. If she gets a rubber line for disc brakes, it may be too short in length, having to loop down then come back up to the caliper. Disc brake hose came from the hardline on top of the rail and fastened to the upper control arm, a straight shot, so to speak.

I would recommend getting the braided hose as it would not expand when brakes are applied as in rubber hose, a firmer pedal feel. If braided is gotten, MB can cover the braid with 2:1 shrink tubing to protect the braid and protect hands from scratching.

Just my thoughts, if I'm wrong, educate me. I hope MB has a good present opening at NPD.
At the caliper, each side has a very short metal brake line, I think they are about 9.95. These are AFTER the rubber line going into caliper, hope this helps.
Hey Everett -

I asked the question last week - braided or rubber - didn't get a ton of replies, but Don, (ZZ430Droptop), said to go with the rubber as he has never noticed a difference in pedal feel. A bit more research and some views were that the braided hoses don't allow for inspection of the hoses as the braids cover up the real hose underneath.

After all that, I bought braided!! but because I'm doing a swap and needed custom lengths is all.
Thanks for the link and other info. But see you still made the correct choice as a properly built braided hose is Teflon inner lined hose and the braid protects it from the ultraviolent rays to prevent dry-rotting.

If my choice, I'd still get stainless braided. Can't hurt.
Had a blast...expensive but fun still the same. Everett, you are correct. Brake change over from drum to disc and these lines are too short. I'll be sending them back. Since that is the case, what are my options???

BTW, the baby got new fenders and cowl hood....
You should a tape measure and measure the length of the hose now(?) or what may be needed and if you have a good parts person, there should be a listing of part numbers for longer hoses with the same ends for the application, if you have rubber hoses. Braided lines are, I believe, are more limited to stock replacement. At least I haven't seen/read of the braided hose manufacturers follow the same route.

And yes, you want to buy a ready made hose as it has been tested to SAE stds and for liability reasons.

I don't know if NPD has this option, but most local parts stores do, since they deal with more variety of parts.
And the drama continues...just got back from the local Autozone with the line we took off the caliper. Guess what? It came from a 72 vette. This project gives new meaning to the term Hybrid. Goodness gracious. Now I don't know if anything else will fit.
Can anyone tell me who has front brake hoses at least 18" long with the same ends as the performance lines in Ricks #J717S (this is similar to what we took off my car)

We placed an order with ground up for 69 disc lines and the caliper bolts. Seems my lines are vette lines but the calipers match every 69 single piston caliper photograph I have looked at. Your opinions? (as always highly valued)
Most every caliper I've looked at has Rick's J379S hose. Your J717S is for drum brakes. Banjo fitting with a banjo bolt through it sealed by two copper washers, (J379S)

Were the brakes working when you bought the car? A drum hose won't fit a caliper, or so I thought.
That's what I thought. AS for whether or not the brakes worked I don't know. I wasn't overly concerned as they were to be replaced anyway, but what a hodge podge of stuff to put this thing together. We bought J379S and this will be put back together properly. Eventually, when more $$ becomes available I'll change it back to 67 system, but for now all parts but lines are still good.
Your opinions? (as always highly valued)
Thank you, I apologize for being rude and not acknowledging. I'm learning also.
You have not been rude in any way, no apolgy necessary. I highly value all of the opinions I get here. I look at what everyone tells me and use the best option given, according to what the checkbook or visa card says I can do. With the help of you and everyone else who responded, I think (hope) we have resolved the problem.
Cool! You're welcome.
