Good Morning, so I think I have narrowed down the lack of fluid at the rear cylinders to be a brake line failure. When the rear line was disconnected from the proportioning valve, I disconnected the line at the rear passenger cylinder as well as at the proportioning valve. I was not able to blow any air through the compressor from either direction through the lines. However, at the same time I could not find any leaks of air coming out of the line anywhere. The air hose would blow off when it reached approx 15-20 psi. When I connected vacuum at the rear brake line, I had no vacuum at the line by the Proportioning valve. With all that being said, I am presuming the rear rubber hose has collapsed. I figured while I was changing out that, I would replace the steel lines as well, but I am baffled as to the clips in the picture. Can anyone share what they are, how they come off, and where I might get them. I did not see anything like it on Inline Tubes website.

Thanks, Timothy

 

They are just pieces of steel spot welded to the axle tube. You carefully bend them up to release the tube and carefully bend them back down to retain the new tube. Yes, they can break off if rusty or over-bent. That's life. These cars were designed to be cheap to assemble and last a few years. No one ever intended for them to be around half a century later.
