Technical 1953 Chevrolet 3100 / master cylinder / brake line

Hiya folks.

vehicle in question:

1953 Chevrolet 3100 series(half ton) pickup

I am trying to replace all of the brake lines as I had a rupture last year, I have all of the lines removed, finally.

I had to take the MC off the truck in order to get this brake line loose.

I have questions about the line that goes into the back of the brake master cylinder, it has a thread on it, then it passes through the brass piece on there.

Can I buy a new brake line with this thread on it? I've never seen a brake line quite like this before, so I'm guessing the parts store people will be equally confused.

Any help on terminology or a parts source is appreciated, thank you.

maybe you could upload the photos to the HAMB so we can see them more easily?

but you just need to take it all apart. The threaded thing going through the brass piece is a banjo bolt, the fitting itself is a banjo fitting. Generally we re use all that stuff, after spending an hour getting it freed up from the rust.

be sure to use new copper washers.

 

Here are the photos...

 

A typical brake line is threaded into the banjo bolt. Yours looks like a one piece deal because the tube nut is rounded off.

 

Now you went to all that work , you might as well rebuild/replace master cylinder if it's been sometime.

 

replace with a dual master? ditch the banjo bolt completely

 

Totally agree, though you'll need to make a bracket. We used a 4 wheel drum AMC unit on one project and worked out great, just needed a "custom" bracket anyone could make up to fit the holes in the car. Just pick a master, AMC, Corvette, Mustang whatever is close in size and weld up something stout to fit between it and the car.

 

Thanks for the replies folks, I wasn't sure about that brake line coming out of that hollow threaded bolt or not... being a separate piece. I was leaning towards it being separate, but wasn't sure.

Thanks for the information.

I put the bolt in a vice and took a pair of vice grips to the corroded brake line side, where the nut was rounded off... after a few attempts with the old metal on the brake line flaking off, finally got down to some good metal with a grip and the brake line nut broke loose. Then I was able to take it apart and clean it up.

Thanks for the tips folks.
