Front Brake Line Adapters

Have a 1964 G10 Panel. I have been replacing all of the brake lines, cylinders, shoes, etc. On the back of the front wheel cylinder there is a brass adapter block between the cylinder and the flexible hose. It uses a banjo bolt with copper washers at both ends of the block. I replaced the brass washers and reinstalled the adapter.

I can't get these connections to stop leaking! I have slowed down the dribble, but still unable to get a leak proof connection. What am I doing wrong? It's keeping me awake at night!

just curious-?? did u get the proper copper washers?? ones needed have some circular rings on them that seem to crush when tightened! NAPA will have them.

I've learned to try an not let van issues keep me awake anymore, they always work out...let it go, its not your health, only an old van....LOL Doni will know. I have a '64 too, I'll have a look. I haven't done my brakes yet but a PO did and although the lines look original, the hoses don't look that old and my mechanic said they looked fine....he's not the one crashing his van when they fail though!

Did go to NAPA and got a good match with the copper washers. Should not let this stuff get to me. Never was very good at plumbing.

It takes 3 washers,,,,,1 on the brake hose, 2 on the bolt,,,,,,maybe the hose or wheel cylinder is cracked,,,,,,,you could just test the hose by putting a normal nut and bolt with washers through the block and see if the hose/block assembly leaks,,,,,,

Both sides are leaking. Do have the 3 washers installed. New from NAPA. Cylinders are new as well as the hose. I will try the bolt idea to try and narrow down the problem. Thanks.

Note: When the new wheel cylinder box say :"Made in China," if does make me wonder it that is the issue.

Could be they did not tap the threads deep enough into the wheel cylinder,,,,,the bolt should be able to go about 1/8" deeper than the block,,,,,,look in the hole,,,,,there should not be a seat down in there,,,,,the banjo bolt is just a plain old fine threaded American bolt,,,,,,,

We also use the braided brake hoses on our vans,,,,,,

what place did u get the wheel cyl's from ??????? NAPA? made in china??

This probably is not the issue here, but really inspect the surfaces that the washers must seal on. Any line or dent can create a leak. I have normally run into this problem with remanufactured calipers caused by rough handling of the cores. But it is something that could apply and to be looked for.

All good advice. I will check all these items and let you know what I find.

Thanks for the help.

Thanks to all of you for your help. Looks as if "donivan65" nailed it. Bought a couple of new cylinders from the local NAPA store. Installed cylinders were not tapped deep enough for the banjo bolt to fit snug. Looked and felt tight, but the bolt was bottoming out in the hole. After my happy dance is done, I will get the new ones installed.
Will let you know if all is well to continue on to another step in the restoration.

Thanks again,
Doug

,,,,,don't be dancing if you are still running that suicide 1 line master cylinder on your van......

Thems some heavy words Don! Dual master is HIGH Priority on these vans!

,,,,,looks like he is jumping right in there on the van,,,,,,brakes surely is the #1 priority,,,,,no way that those 1 line master cylinders and 50 year old hoses and metal lines are safe,,,,,,

I agree. Lesson learned. More plumbing in my future.
